The first LaserJet was a high-speed replacement for text-only daisy wheel impact printers and the noisy dot matrix printers. By using control codes it was possible to change the printed text style using font patterns stored in permanent ROM in the printer. Although unsupported by HP, because the Laserjet used the same basic PCL language (PCL Level III)HP 3000 multiuser systems.

HP LaserJet 4 Control Panel: the two-character ready code "00" is a carryover from the original LaserJet display shown above, but the display now features 16 alphanumeric characters, allowing 13-character descriptive messages (after the number and a space). Many options, such as font selection, paper size and tray selection, I/O settings, and test prints are also available at this control panel through a menu system.

The 1992 LaserJet 4L marked the transition between a control panel evolved for an informed operator and one evolved for a casual user. The 4L"s predecessor, the IIIP, had an array of buttons and a cryptic numerical LCD. The 4L shipped with 4 LEDs, each with an icon to indicate a different condition, and a single pushbutton whose purpose varied depending on context (i.e. Hold down during printing, the printer will cancel the job. Hold down when off, the printer will power up and print a test page including total number of pages printed. A short press would provide a form feed or tell the printer to resume from a paper jam or out-of-paper condition. The actual application of the button was supposed to be far more intuitive than any possible written description – basically, the button tells the printer "whatever you"re doing now, do the next most logical thing"). This interface was supposed to be easier for new and casual users to understand and use, but it was also much less powerful, as in any case there is only one thing a user can make the printer do. Until the user becomes familiar with the printer"s behavior, they have to guess what that one thing is, or else consult the manual.

Before the 4L, the control panel typically had buttons with names like Online, Menu, Shift, Continue, Reset, +, -, and Form Feed. It also included status indicators like Online and Ready. Users without a technical background, especially those who had not used a printer before the late 1990s, might not understand these indicators, or might think they are conflicting or ambiguous. It may not be intuitive to new users that a printer that is ready but offline does not print, and while being able to take the printer off line (effectively disconnecting it from the computer) without shutting it down can be very useful, this distinction may appear as an extra complication to users who want to casually use the printer merely as an information appliance.

With the advent of the HP LaserJet 4000 in 1997, the control panel was completely redesigned. The Shift button, which might have been confusing, was gone. There was a Menu, an Item and a Value button. Each of these might be clicked left or right. There was a Select button, a large green Go button, and a small orange Cancel Job button. Configuration through the control panel was easier and more intuitive: menus could be navigated with the Menu button. Then, items within the menu selected with the Item button. The Value button – which had - (decrease) and + (increase) indications – could be used to select a specific setting or value. The Select button was used to select or confirm a particular choice. The display was adapted to a blue-backlit two-line LCD display.

Newer models such as the LaserJet 600 series now include a full color LCD display. Two directional arrow buttons and a Ok button replace the multiple menu navigation buttons of the 4000 series.

TV repair costs between $60 and $350 with most spending $207 on average for LCD, LED, plasma, and 4K TVs; costs are higher if repairing older DLP, projection, and HD TVs. TV problems like display issues, powering-on problems, or sound issues can be fixed. Pickup and delivery fees may apply.

For example, the price of a new Samsung 40-inch LED TV is about $400, yet the cost of a replacement display panel for this model is about $380. This price is only for the replacement part and does not cover diagnostic costs, labor costs, or travel or shipping fees.

Unless you are trying to fix a TV from the ’80s or earlier, cracked TV screen repair is not feasible; the entire display panel must be replaced instead. The cost of a replacement TV display panel is more than the cost of buying a new TV, and that’s before labor and other service costs.

The cost of TV screen replacement is generally the same as or more than the cost of buying a new TV. Therefore, replacing a broken or malfunctioning TV screen is not considered a viable option. If the TV is under the manufacturer’s warranty, the manufacturer may replace the entire unit.

TV manufacturers do keep replacement TV screen panels on hand to support products under warranty in case the screen malfunctions, due to manufacturer defect.

If you still want to replace a damaged or malfunctioning TV screen, your best option is to find a used replacement panel or a broken TV of the same model on which the screen is still functional. You might find one on eBay, and you can hire a technician to change out the panel.

The cost of a used replacement TV panel ranges from $50 to $350 or more, excluding shipping, depending on the brand and size. Note that the chances of finding exactly the part you need in excellent condition are slim, and the cost excludes the cost of installation by a repair shop.

Whether your TV is LCD, LED, plasma screen, or 4K (Ultra HD), the cost to fix common problems ranges from $60 to $350, depending on the repair type and the brand of TV being repaired.

TV motherboard replacement costs between $200 and $350, including parts and labor, or about $275 on average. Motherboard replacement parts range from $35 to $199and labor costs from $60 to $125.

When an inverter component goes bad, it is usually replaced rather than repaired. In some cases, the capacitors on a converter board fail, and a technician can fix it by replacing the capacitors rather than replacing the entire inverter component. However, if an entire inverter board replacement is not available for the model of TV being repaired, replacing the capacitors may be the only option for TV inverter repair.

A flat-screen TV bulb replacement costs between $60 to $115, with most homeowners spending $84 for parts and labor. The price for replacement bulbs ranges from $18.50 to $80.

If an older model LCD TV or projection TV powers on and has sound but no picture, this may be due to lamp burnout, which is both common and expected. In this case, replacing the bulb will fix the problem. An experienced technician should be able to replace the bulb quickly and easily.

TV backlight repair costs $100 to $122, including replacement parts and labor, at a repair shop. In-house repair costs are more due to trip fees. The price of backlight replacement parts averages around $2.50for each LED and between $20 and $25 for each CCFL strip.

Repairing a TV power supply board costs $23 to $234 for parts alone. Completely replacing the power supply board costs $250 for parts and labor. If one capacitor has failed, the cost for replacement capacitors is low. However, it’s more cost-effective for the technician to replace the entire board rather than spend time trying to diagnose and replace faulty capacitors one by one.

TV capacitor repair costs $60 to $129, including parts and labor. The cost for the replacement part ranges from $0.06 to $14, with the labor portion ranging from $60 to $125 per hour. TV capacitors protect the circuit from getting too much power, filter signals, and facilitate changing channels.

Flat screen replacement glass is not available. The only option for flat-screen TV glass repair is to try optical glass glue, which costs $1.70 for a 5-ml. tube. This may be an option for TV glass repair if the crack is only a few inches or less. TV panels are built as one unit at the factory, with the glass adhered to the display panel.

A TV fuse repair costs between $61 and $136, with most spending $99 on average. The cost of the replacement fuse itself is $1.50 to $11, while labor ranges from $60 to $125 per hour. Additional fees may apply.

LCD flat-panel repair is not considered cost-effective. If the glass is cracked or the display is physically damaged, it is cheaper to replace the entire TV than to repair or replace the display panel.

More popular TVs are usually less expensive to repair because repair shops order replacement parts for them in bulk, which allows them to buy those parts at a lower cost.

The cost of flat-screen TV repair ranges from $42 to $359. You cannot fix a broken screen, but the price of a new flat-panel TV starts from around $249 for a 1080-mp (non-4K) LED TV from LG to as much as $14,999 for an 85-inch 8K LED TV from Samsung. A TV referred to as a “flat TV” or “flat-screen” TV might be any of the following:

LCD TV repair typically costs $60 to $85 for diagnostics testing, and $200 to $300 to perform repairs. LCD TVs use backlighting, which may fail. Newer LCD TVs use LED strips for backlighting. Older ones might use CCFL. If CCFL backlighting fails, a technician can replace it with LED backlighting.

An LED TV is just an LCD TV that uses LED backlighting, which all newer models do (older models use CCFL backlighting). The cost to replace one LED backlighting strip ranges from $100 to $122, including parts and labor.

With modern TVs, repair entails component replacement or replacement of capacitors, for which high levels of certification are not necessary. Generally, TV repair shops will let you know if their employees have certification.

First, check that the connecting cable is securely in the socket on both ends. If that doesn’t work, try substituting another data cable if you have one, or test it with a replacement cable.

Circuit breaker - Check the circuit breaker for the power outlet that the TV plugs into. You can check the breakers by opening the door to your breaker panel and looking for circuit breakers that are in the OFF position.

Power cable - Check the power cable. If it is a removable cable, you can test it by substituting a power cable from another piece of equipment in your home, or you can buy a replacement cable for this test. The cost for a replacement TV power cable ranges from $2.50 to $10.

Lamp burnout -In a projection TV or older LCD TV, no picture may be caused by lamp burnout. In this case, a technician can replace the bulb quickly and easily.

The right parts - It can be complicated to determine which component of a TV is failing and causing the TV not to work correctly. If you buy a replacement part and perform the repair yourself, the TV may still not work, either because you replaced the wrong part, the part was old and not working properly to begin with, or you did not perform the work correctly. Buying multiple replacement parts can become costly.

In most cases, a flat-screen TV can be fixed. The exception is a physically damaged display panel or screen. Most other issues including failing speakers, backlights, or power supply. Burned out fuses and damaged input ports can also be repaired.

Accidental Damage is any damage due to an unintentional act that is not the direct result of a manufacturing defect or failure. Accidental damage is not covered under the standard warranty of the product. Such damage is often the result of a drop or an impact on the LCD screen or any other part of the product which may render the device non-functional. Such types of damage are only covered under an Accidental Damage service offering which is an optional add-on to the basic warranty of the product. Accidental Damage must not be confused with an occasional dead or stuck pixel on the LCD panel. For more information about dead or stuck pixels, see the Dell Display Pixel Guidelines.

The LCD glass on the display is manufactured to rigorous specifications and standards and will not typically crack or break on its own under normal use. In general, cracked, or broken glass is considered accidental damage and is not covered under the standard warranty.

Spots typically occur due to an external force hitting the screen causing damage to the LCD panel"s backlight assembly. While the top layer did not crack or break, the underlying area was compressed and damaged causing this effect.

If your Dell laptop LCD panel has any accidental damage but the laptop is not covered by the Accidental Damage service offering, contact Dell Technical Support for repair options.
