How do you a Clean a Flat Screen TV?

Answer 1

Televisions are complex devices and modern ones use automated production to ensure the quality of the components that deal with the high data throughput found inside them. Fixing a television now requires information and tools only available to commercial repair centers.

Older CRT televisions are somewhat simpler but anyone asking this question should be warned that they contain lethal voltages which can remain present for days or weeks after the television has been switched off. If you are not qualified and experienced, avoid remove the case of any television.
A TV repair is best left to the professionals.

Answer 2

Sadly, the days of tinkering in the back of a television to fix it are well and truly gone. Even independent TV repair companies are limited to replacing modules in LCD and Plasma screens. Anything more intricate and they have to go back to the manufacturer. Without the right parts, manuals and test equipment, there is simply no way to do it yourself.

Even worse, repair costs are so high these days, that often it just isn't worth getting a repair done because it can be more than buying a new one.

It depends on the type of television and what is wrong with it. You would likely need to know basic electronics and have access to service manuals to do this.

If it is a CRT television, one of the first things you have to make sure you do is to discharge the CRT. To do that, you would have to have the unit unplugged, and you would run a wire from the "2nd anode" (the big wire going to the back of the picture tube and looks like it has a suction cup on it) to the chassis ground (just follow the wires connected to the springs grounding the picture tube).

If it is dead, you should check the fuses inside. But you should visually and electrically check the areas surrounding the fuses to see if other things need changed. For instance, you should check nearby diodes to make sure they are not shorted.

If the edges of the picture is moving around in a CRT television, that could be a capacitor in the vertical refresh circuitry.

Arcing can be very troublesome and may happen in a CRT television. That could be a sign that the flyback transformer (feeds the "suction cup thingy") is going bad, or the flyback's wiring is shot. You can sometimes fix this temporarily with some sort of "dope" or tape to act as insulation.

Intermittents are one of the worst problems to troubleshoot. That is when it works sometimes and not other times. That can be caused by a break in the circuit board or a bad solder junction, and they can be very difficult to find.

Answer 4

In which way? This depends on what you need fixing. The easiest way though is to buy a new one. It also depends on brand and product. or try switching the white wire ,take the bendy bit out swap it around and put it back in again

Answer 5

Throw out the tv. An area in the back stores electricity and you can get shocked if you mess with it. When tv's had tubes, they were repairable. Electronic circuit boards aren't worth the effort or cost in most cases.

Answer 6

You can find a product that helps repair the scratch, or make it look less noticeable. It will be very pricey to fix it your self. Look in your TV manual, call the number and they should be able to tell you.

Answer 7

You can clean a flat screen TV by taking a dry soft cloth and wiping. Do not use water because it will leave marks on the screen.

Answer 8

It's possible.
