lcd screen turns white factory

2023-01-03 12:32:11

I had the same problem. Did the same test and then replaced the screen. Still same results, any ideas. So far I replaced the screen, motherboard, and the inverter.

If you’ve replaced LCD, motherboard and inverter but the laptop still has the same problem with video, then I would assume the problem is related to the video cable.

I’m new to this and have only handled a few different models/brands but it seems to me that most lcd video cables have different connectors (where they connect to the motherboard). Is the connector on the back of the lcd the same so that you can swap any lcd for testing or do they all have specific connectors on the back as well?

Different LCD screens have different connectors. If you want to test your laptop with another screen, you’ll have to remove the screen from your laptop and compare connectors.

You said the screen is black. How black is it? Can you see anything at all, maybe a very faint image? Did you test the laptop with an external monitor? Can you get see external video?

Mine is a Compaq, when I move the screen forward of backward it flickers and gives a damaged image when get my hands off of it it works well,,,, can u assist me please… and thanks in advance

Test your laptop with an external monitor and find out if the external video goes bad too when you move the laptop LCD screen. I’m just trying to narrow down the problem and find out if it’s related to the LCD screen or something else.

Hi from Italy, my brother’s notebook, an Asus L3TP L3500, has a white screen since 4 years: Many people look into it to find what’s going wrong: at the end, after many years and many repairers, this is the response:

Thanks CJ. Do you know how many different kinds of connectors there are? I would buy a cracked screen of each kind to use for testing if there were just a few different types.

I’ve got a similar problem toFathi (13) but mines an acer. When I apply pressure to the keyboard area or bend it slightly the screen goes flikery and messed up.

HI, I WAS WONDERING IF ANYONE COULD HELP ME LEARN HOW TO REPLACE MY LAPTOP RIBBON CABLE FOR MY SCREEN FOR A HP DV8000. I WOULD LIKE TO DO THIS JOB MYSELF BUT I DO NOT KNOW HOW TO TAKE APART THE LAPTOP TO DO SO.

on a HP dv4000, I can barely see windows on the black lcd screen, no backlight, with an external monitor only works if the lcd cable is disconnected from the motherboard, is the problem the motherboard? need advice……..

3. If 1 and 2 do not help and you still having the same problem, most likely it’s related to the LCD screen. If that’s the case, you’ll have to replace the screen.

Do you know how many different kinds of connectors there are? I would buy a cracked screen of each kind to use for testing if there were just a few different types.

Be careful when you buy a cracked screen for test. If the screen is cracked badly, it’s possible you will not get any image on this screen, so it’s not really good for test.

Would it be totally safe to assume that at least the same model, but different cpu speed, would be usable for testing whether a larger lcd would fry the system?

I have a c400, it has heating issue and 12 inch lcd. There is a c800 with a 15in lcd (I believe). I want to put my c400 in a totally custom case, and need to find out if a c800 lcd plug is the same as on my c400… and whether the system can take the strain of the larger panel (battery life is nothing to me)…

i Got a Problem With my toshiba Laptop When i Turn it on it Turns Like orange Pink Color N i Tried My Computer screen didnt Work either. and if U Can Help Me Fix this Problem N thank You.

I just want to thank you for your advice on making sure that the video cable is securely inserted. That fixed the white screen trouble with my HP laptop.

I have a question well i came up with an idea but I don’t know how do able it is. Is there anyway to connect the LCD of the laptop to the external VGA?

Can you tell me if i can test on this laptop a 14?lcd (from a nc6000). The connector on the motherboard is the same but all i have is a series of coloured lines.

My LCD is completely white, i have disassembled everything and re attached the cables, still white. Tried an external monitor and that works. Am i safe to assume the LCD panel is dead?

The only way to find the culprit is testing the laptop with another working screen. If you still have the same problem on another screen, it’s bad motherboard.

Really nice usefull information.. thanks for the nice work. I have an issue with my laptop display. the display is fine in the first half the screen and the rest of the screen is just white.. i tested external monitor and it works fine. Please advice.

Hi. I have a problem where the screen is normally white, but I get an intermittent display depending on how I move the laptop. It generally works best when I tilt the laptop backwards.

Usually it’s bad connection between the video cable and LCD screen. Did you try reconnecting the cable? Just remove it from the connector on the back of the LCD and then connect back.

If reconnecting the cable doesn’t help, it’s possible that you have bad cable. Could be faulty LCD and even motherboard, but I would try replacing the cable first. It shouldn’t be very expensive.

Ok guys, this is driving me nuts. I have a HP Pavilion dv6000 and it works fine. The backlight works but I do have a screen problem. The bottom third of my screen looks like a large bar code. It doesn’t display anything except a bunch of vertical lines. When I plug into an external monitor, everything is fine. Any suggestions?

Ok i know this is kind of a stupid question but could you tell me the name of the connector that would connect into the video card. I am working with an Inspiron 5100 (yes i know ancient) but i am taking the screen out and converting it to be used somewhere else anyways if you know the name please tell me.

The new screens ie LED screens dont have an inverter. I have heard that most laptop companies want to use these new screens. I still havent seen a white screen on an led yet. Thanks for the comments

Do you mean loose connection between the video cable and LCD screen? I guess it’s possible, try reconnection the cable. If no help, probably it’s the LCD screen problem.

My screen had a one pixel vertical bar down the middle of the screen. then one day it just all of a sudden went completeley white. However,when I move the screen to certain angles It flickers back into a seeable image of the login screen before it again fades slowly to white.

I sent it in to hp for repairs, and they told me it was going to be a lcd screen replacement based ON the vertical bars that they saw. I just want to ask if its possible that the vertical bar was the catalyst that set off the entire screen breaking, as it seems that only that bar was there one day before, and one day later the screen completeley broke (without being subjected to any heat or pressure. (They are trying to charge me 450$! and I think that my case should be covered under my 3 year warranty! Especially because it was a 2k business notebook at the time of purchase)

In my case, toggling back and forth from external to internal screen I can manage to get the video back on my laptop screen. Sometimes I turn it on and it is white, some other times it is normal, and some others, I lose the video while working! Any ideas on that? Fiddling around with the screen, repositioning it or moving it in anyway does not bring the video back.

I have a similar conundrum. The Toshiba Satellite A105 started with a white screen now – nothing at all. I read to try pressing on the outer edges of the LCD screen – no change. I connected it to an external monitor and it worked great. When I unplugged the monitor and tried to go back to just the lcd screen, now I have nothing – black screen. I tried removing the battery and ac power and pressing the power button for a minute. After I put everything back, I turned it back on – still black. I removed the screws that held the top half of the laptop (kb, screen, touchpad, etc…) to the bottom to try to see where the screen connected to the main board. I removed and reseated the cable, verifying that there were no bent pins and everything lined up. When I put everything back together and tried turining it on nothing – still black. I checked the cable again – no bent pins and everything was aligned – still black.

I know the problem could be the screen, the inverter, the cable or the mobo. Since I have a limited income and if I tried all 4, I would be at the cost of a new laptop. Can anyone help?

hi I dropped my laptop bought a new screen and replaced it and it just shows a white screen I took it apart again and saw damage to the data conenction ribbon how much about isit to repair thanks

Ive got a Hi-grade EAA-89 laptop a few days ago. when i switched it on the screen just went white with a few vertical white lines across the screen after i leave it on for a few mins, the screen seems to split into two halves one being white and one dark grey/black.

2) during the boot up procedure if i press FN+F3 with an external monitor plugged in it will switch over to the other monitor however the picture seems fuzzy sometimes with random distortion shooting across the screen for a few mins but then windows runs fine.

3) But if i press Fn +F3 with no monitor connected then it seems to switch over somehow and display the picture, however this only lasts during the DOS/BIOS selection (ie: how do you wish to start windows………..) as soon as i select any option to get into windows then it goes white again ????

I PHONED A FEW COMPANIES WHO IMMEDIATELY TOLD ME IT WAS THE SCREEN BEFORE LISTENING TO ALL THE SYMPTOMS WHICH TELLS ME THEY WANT £150 OUT OF MY POCKET, SURELY IF THE SCREEN WAS DEAD I WOULD NOT BE ABLE TO VIEW THE DOS BOOT SEQUENCE? I WAS THINKING IT MIGHT BE THE POWER INVERTER BOARD IE: IF WINDOWS TRYS TO DRAW MORE POWER THEN IT CAN PRODUCE, OR POSSIBLY THE GRAPHICS CARD THAT WOULD EXPLAIN THE FUZZY BITS WHEN AN EXTERNAL SCREEN IS CONNECTED.

I have a question about what to do with an LCD that will not display. I have a Compaq v2424nr and my LCD stopped working, but if I plug in an external monitor it works fine.

If I tap on the button that puts the computer into standby when you close the lid the LCD screen blinks to the tapping of the button, it tries to turn on but won’t and the screen looks ok (a little reddest as it flickers). I have changed the settings for the display and nothing works.

I have read through the guides and I am ready to tackle the repair, but where to start? I took the computer into a shop and for $40 they said it was the LCD and could replace it for $525 (way to much).

I checked the standby button (lid close button) to see if it was dirty or loose. The rubber extension for the button was clean and the switch itself does not seem loose at the circuit board. But if I play with the switch (tapping it down) I can get the screen to flicker.

You mentioned that the screen turns on for a moment and it has reddish tint, right? It tells me that most likely you have a problem with the backlight lamp but I cannot be sure without testing the laptop with a known good inverter.

You said the repair shop quoted you a new screen, apparently it’s a problem with the backlight lamp which is located INSIDE the LCD screen. I assume they already tried a new inverter, you can ask them. Most repair shops will not replace backlight lamps and they quote you a new LCD screen instead.

If you have no experience, there is a really good chance to damage the LCD. But if your repair is successful, it will cost you less then $20 instead of $525. Proceed on your own risk.

I have an older laptop (Gateway SoLo), the connector to the LCD was a different size so I couldn’t try that without taking the LCD apart further (i didn’t check to see if the cable to the notebook card was the same, figured it was also different).

Yes the screen flickers (only for a second) as the laptop is turning on or switching between displays, and as I play with the switch. I did call the shop after I found out there was an inverter and bulb that could also be wrong, but they didn’t remember if they checked the inverter, just said they found the LCD bad…

when you said you have a test LCD does it have to be the same LCD what matches the model of the laptop or can you use any laptop LCD to test these problems

i have a problem with an Acer Aspire 3610 screen, when i switch the computer on the screen goes full white and then fades into the normal view slowly and with blotches, and the mouse arrow cursor moves really slowly, here’s a video of waht i mean: http://uk.youtube.com/watch?v=8QqJ-21yCJc

He is still working perfectly as long I DO NOT MOVE THE LAPTOP OR THE SCREEN. THEN THE SCREEN IS BECOMING OF DIFFERENTS COLORS WITH LINES OR SQUARES, WITH OR WITHOUT THE POINTER APPARENT ON IT. SOMETIMES THE SCREEN TURNS BLANK.

I CONNECTED AN EXTERNAL MONITOR AND IT WORKS FINE (TOGETHER WITH THE LAPTOP SCREEN) AS LONG I DO NOT MOVE THE COMPUTER OR THE SCREEN OF THE LAPTOP. THEREFORE I PRESUME THE PROBLEM IS NOT IN THE SCREEN OF MY LAPTOP.

I presume the fault is coming from a short or a loosed connection between the SCREEN and the COMPUTER (because of many years of opening and closing the laptop) or A LOOSE CONNECTION IN THE MOTHERBOARD (VIDEO/VGA).

HI, my sony vaio VGN-CR25G laptop LCD screen turned completely white. But I’m sure that the OS is running, Keyboard is working; everything else is working except the LCD screen.

Unfortunately, I cannot tell which one is bad without testing the laptop with a known good screen. One day we had two laptops in our shop failing exactly the same way as yours. One of them had a problem with the LCD screen and the second one a bad motherboard.

Hi, I seem to be having a similar problem. My screen is completely white but when I put pressure on the top part of the laptop screen (where I’m told the connectors are) I can get an image on my laptop. It is too painful to keep putting pressure with one hand on the top part of the screen. Do you think this is simply a problem with the connection? Everything else works fine as I am actually using my laptop and typing this with one hand.

I have a similar problem to Joseph, in that squeezing the plastic on the sides of my Inpiron E1505 LCD fixes the problem, for a while. It seems to happen randomly – the image will fade away to white, sometimes slowly, sometimes more quickly. Rocking the LCD screen back and forth or squeezing the sides seems to help. Any ideas?

Nope, the model was different but it looked very similar to the original LCD installed into the laptop. Same size, same type of connector on the back. It just happened that I had that cracked screen under my bench.

Yep, it might work as a temporary solution. Also, you can use a piece of pen eraser and placed it inside the display assembly between the LCD screen and cover. When you assemble the display back together, the screen cover applies pressure on the LCD screen because there is a piece of per eraser between them. Might work too.

I have a similar problem where my toshiba M302 screen goes totally blank or the picture becomes unsteady. When I use pegs to hold the sides it becomes temporary steady.When I remove the pegs, it goes blank again. As a lay person, I was told it was a fibre problem. I am yet to find a solution to it.

I have a customers Vaio CR510e. The LCD is white with little black spots. When you lightly tap the LCD you can see video. Connected to an external monitor everything works fine. What do you think? Someone suggested the video cable from the MB to the LCD.

Over the course of a few weeks, my LCD display has been acting off. I could turn the computer on, but whenever the screen refreshed completely, it would come up white with faded lines. Sometimes, depending on the angle of the lid, the screen wouldn’t come on at all.

good day i need help.. i have compag presario 2100. the problem is when i turn on the screen appear pure white but after 15minutes waiting i see on screen working fine but if i restart it back to white again then wait another 15minutes.. i check all the video cables but it plug properly.. thank you please reply

Im in a bind. My screen is completely white. I have the toshiba satellite. Can u help me fix the problem because, i have so much memory on it. For me just to take it to a computer repair store is 100.00. Thats for the estimate. And no telling how much to fix the screen. I really do not want another laptop. I love this one. Please help me out of this crisis.

I have a Sony VGN-S150 laptop. One day when i pressed the power button, the screen went “white” (gray-bright actually)and held there,HDD still running, nothing else, and my laptop could not start, even the boot logo.

But the interesting thing is, when the laptop not responding, if i turn off (by press-n-hold power, wait for HDD stops) and then turn on immediately, it will work as normal ( boot, starting windows,…), but the screen gets white again if at screen saver mode (turn off display).

I have a compaq presario 1500, the monitor is white but works with a external hooked up. How do I fix this problem? I see someone fixed it but was still white and the screen needs replacing. But I need to make sure if it can be hooked up on the inside first. This would help very much. Thank you for reading this.

THE main PROBLEM: OK i have an inspirion 1520 with 8600mgt. i was playing a video game but then my graphics drivers crashed, so i went to start> shutdown and i restarted the computer. when i turned it on again everything was ok so i turned on the game again. this time graphics driver crashed again but this time i had to shut down by holding down the power button for 10 seconds. now when i restarted the computer, the screen is BLANK AND BLACK, nothing shows up..no bios boot page, no windows logo, nada. i reckon that the system still runs b/c i can still hear the windows sound when i log into my account (yes i logged on blindly). also i can turn up and down the brightness, but i just can’t see anything, CAN ANYONE PLEASE HELP ME? i update my computer regularly and had the newest bios, i was running windows xp sp3/

I have HP Pavilion ZD8000. it boots Ok but there ia 3inch vertical line to the left of screen. After copmletion I can see WindowXP logo and finaly for moment or two I can see mosuse pointer the the screen goes completely white. I have tried external monitor and it shows some red and orange bars. Can you help me as if motherboard was faulty, I should not get all bootup info, windoXP logo etc. Please can you diagnose from this info , problem with my laptop. The inverter works OK.

It hasn’t got a white screen but it has developed a thin vertical line an inch in from either side of the screen which is various colours depending upon the background colour. Thinking it might be the cable or possibly screen, but getting an external monitor would be cheaper than replacing the laptop screen…but if the screen eventually dies completely, would want to know that the external one will work without needing to get into windows first…

I’m actually asking this on behalf of my Mum who doesn’t live near me so I haven’t actually seen the screen. Yes it sounds like she has a 1 pixel line down the screen – two of them either side. I thought it might have been the cable, but perhaps it is the screen. She is taking it to someone to look at today. I thought I’d ask about an external monitor as getting the internal laptop one is going to be expensive as it has to come from overseas…she hasn’t got access to an external monitor otherwise I would already have got her to try, hence my question.
