canon 70d lcd screen not working made in china

Today after noon, I have worked for two hours and turned off the camera at location. On the way home i have turned on the Camera, but back LCD stopped working. Able to boot the camera and took couple of pictures without back LCD working.

1. Turned on the Camera, Took the battery and SD card out of the camera. After 5 min, I have kept the battery and SD card into the camera and turned on: LCD not working. Able to take pictures.

1.) Press the "INFO" button on the back of the camera. Press it repeatedly and it should cycle through the different modes. One of the modes is actually "LCD OFF", so that could be the culprit.

2.) Also make sure that the rubber "eyecup" padding has not slid up 1/4 inch and covered the "display off sensor" that turns the display off when you put your face up to the camera. If that rubber eye pad (or dirt or makeup or your thumb or anything else) is covering the sensor, then the display would turn off thinking you have the camera up to your face.

If you own a Canon camera and are facing some unwanted errors related to its memory card, then you have come to the right place. While Canon cameras are quite reliable and are widely used the world over, they can be a bit unpredictable.

For instance, users often complain of memory card errorson Canon cameras. Don’t worry – this will be the last guide that you will read about memory card issues on Canon. We have listed all the commonly occurred errors on Canon and have provided their solutions as well. Let’s get it started!

A lot of times while working on Canon cameras, users get unwanted errors. There could be a hardware or a software reason behind these common issues. While some of them can be related to your memory card, others can be triggered by something else. Here are some of these common Canon errors with their quick solutions.

Users mostly get the Err 02 displayed on their camera screen when there is an issue with the memory card. Ideally, the camera is not able to read the memory card or access its stored information. Here are some ways to fix this memory card error on Canon.

If nothing else works, then format the memory card. You can do it by visiting your camera’s settings. Also, you can attach it to your computer and do a quick format as well.

We get the Err 04 on our Canon camera when the memory card storage becomes full. This means, the camera is not able to save the new photos and is running out of space. Thankfully, it can easily be fixed in the following way.

If you are not able to delete the contents of a memory card, then make sure it is not locked. The left slide should be up (and not down). If the lid is up, then it means the card is unlocked and its photos can be deleted.

The Err 10 on a Canon camera occurs when there is an issue with the file system of the memory card. There could be a software-related issue with it as well.

Switch off your Canon camera and remove its battery. Wait for a while and insert the batteries again. Now, switch it on and see if it resolves the issue.

Besides the above-listed memory card errors on Canon, users can encounter some specific problems as well. For instance, your attached memory card can be inaccessible or even be corrupt. The good thing is that most of these problems can easily be resolved. Here are some of these common memory card errors related to Canon cameras with their easy fix.

Too many times, the photos and videos stored on the memory card become inaccessible. That is, users are not able to view them or even transfer them to another location. If ignored, this can lead to a permanent loss of data.

If not, use a dedicated data recovery software like Recoverit Photo Recovery. This will help you retrieve the inaccessible photos and videos of different formats from your memory card.

A Canon camera can’t always read all kinds of memory cards. If you have attached a corrupt, non-compatible, or damaged memory card, then you might encounter this issue. If the card can’t be read, then the camera won’t be able to store your photos.

A corrupt memory card is one of the major reasons for this. Also, if the card is not compatible or runs on a non-supported file system, then it can lead to this problem.

Sometimes, while transferring data from one source to another, users face unwanted lags. The processing speed of your card or camera could be affecting this.

To resolve this memory card error on Canon, simply unmount the card from the camera first. Now, check the position of the lid. If it is up, then it means the card is unlocked. If the lid is down, then the card would be locked.

While the situation might seem like a nightmare, chances are that you might end up losing your stored photos or videos out of the blue. In this, users are not able to access their stored photos/videos anymore.

If you have lost some (or all) of your photos/videos from your Canon camera, then you should use a data recovery tool. A good recovery software will be able to retrieve all kinds of lost and inaccessible data from the SD card.

Recoverit Photo Recovery is compatible with Windows as well as Mac. Here’s how you can recover your photos from Canon using Recoverit for Windows. Mac users can turn to the page:

1Firstly, the software lists all detected data storage devices for you. So please unmount your memory card from your Canon camera and connect it to your computer in advance.

Your Canon camera memory card will be scanned thoroughly to search for all your lost photos and videos. We also offer a deep scan mode in case you need it.

Make sure that you only use a compatible memory card. That is, the memory card should be supported by the camera and should not exceed its supported storage capacity.

By following this guide, you would certainly be able to resolve the common memory card errors on Canon. We have covered a wide range of solutions here so that you can get rid of every major kind of memory card error on the Canon camera.

As for now, lens is mechanically completely sorted and working after just one evening of tinkering and practically for free. With some critical findings about inner works of this lens.

I have a Tamron 17-50 that have some “fractal” patterns on the front element. I treated it as fungus, and as it didn’t dissapear, so I guess it is a cement issue. I bought another 17-50 with broken electronics as donor, and I plan to change the front element, as it is much easier than reparing the electronics (probably a broken flex circuit). Do you know if I need to do any adjustment to the front element after replacing it?

I don’t know, how exactly the Tamron 17-50 is, but You can find out quickly: if there will be a possibility of turning the front lens after loosening of the 3 screws , then has an axial adjustment, which normally adjusts the focus on infinity to be on the same position for 17mm and 50 mm. If not, another methd for Tamron is to use some washers under the 3 scruws, which go in from the outside. BE CAREFUL BY LOOSENING, as they are NOT ALWAYS of the same size – they adjust by some Tamrons (150-600 for ex) the tilt of the front lens – so the right-left and up-down side focus.

Hello, I have been reading some from your blog and I would like to say thank you for such a great resource. Sadly, there is few out there. I, myself have been tinkering with my lens and tried to restore the ultrasonic motor that was working poorly. While cleaning it, I accidentally broke this plastic/acrylic half moon ring that is moving in a circular motion and being read with some sort of sensor with a small plastic piece on it as well. I believe you call it “optical encoder ring(I might be wrong here?). It tried to put it back together with glue and polish it but that made the “encoding (?”) disappear. What would be your best suggestion on how to move forward now? It would be really sad if I had to throw away the whole lens because this little plastic thing is broken and there is no spare parts
