you can try toothpaste. use on the scratched areas in a circular motion for around 5 minutes. This can reduce, and remove scratches from plastic, and even glass. Wipe of with a clean soft fabric or tissue paper lightly moistened.

Another solution is scratch-out. Which is used to repair spiderweb scratches in the clearcoat on automobiles. This is a polymer coating on cars. Your screen is also a polymer. follow the directions carefully, and don't get too aggressive with it. If it doesn't work, what you lost?

The poster above is obviously inexperienced with this type of thing.

Hello
I don't understand your TVs problem. You only posted "Audio Output". What do you mean by that? What is your TVs problem. Please clarify with details. [email protected]

Hi,

I am sorry to hear this. There are only ' limited ' tricks you could apply as deep scratches are usually very hard ( or nearly impossible ) to remove. You could use few tricks to lessen their affect. You could try to use Meguiar's PlastX which is a plastic scratch/buffing product. This is the best available product on CRT monitor.

Note - As i mentioned the effect could be minimized but cannot be repaired. Other stuff available in the market could harm the screen and make it even worse.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hi
Typically, all lcd screens have a protective film coating that is scratched is not the matrix. If the scratches are not deep you can try them polished tool for polishing cd drive. If you scratch deeper and you will not be able to remove them yourself, contact a service center to replace the protective cover the screen it will cost a low price

Is it the screen itself or the protective screen that is scratched. If it's the protective screen, then you can just remove that, but be warned the lenticular screen is now prone to scratches from kids, dogs or a clumsy significant other. But if you feel comfortable with no one bumping into it, then you can remove the protective screen and actually get a better picture quality with no glare.

If it's the actual lenticular screen (one behind the protective screen) then your in trouble and it will cost a pretty penny to get fixed. You can switch it out yourself once you buy a new one, but have two people handy, the instructions on how to replace should be in the owners manual.

HELLO

Sorry - there is NO fix for it! When an LCD/Plasma screen gets bashed or scratched it's damaged forever. A new screen will cost more than a new TV.

Press and hold menu button on your TV and menu button on your remote at the same time.

You must determine whether or not the scratch is on a protective fromt screen or the panel itself. I don't know your specific model, but some of the LGs have a front glass behind which is the actual panel. If that is the case with yours, you can replace the front glass. If it is only the panel, then there is no way to repair other than replacing the panel which is VERY expensive.

If you wish to try something, go to a local auto parts store and purchase a windshield repair kit. This will contain an optically transparent epoxy that can fill in the scratch and make it at least less noticable similar to filling a scratch or crack on a windshield.

try to check the menu your the timer is on.if not resolder the main board of your tv.

as you have seen inside that no power & no light. problem seems to be in power supply. 1 check fuse. 2 check switching ckt. 3 check for loose contact or print break. 4 now if you get power on & still tv is not ok then check for hor. output transistor in hor. output stage. if you are not tech person please do not try to fix it as high voltage is there inside.

Try toothpaste first. take a cuetip, get a little on it, and rub in circles, if it's a longer scratch you can just use your finger. Rub in a circular motion for a few minutes. Clean it off with smooth cloth or tissue paper lightly moistened. Make sure that it's a very soft cloth or you can scratch it further.

the other thing to try is a product called scratch-out for cars. It removes scratches from the polymer clear-coat of cars. follow the directions carefully, (rub on, let dry, rub off with clean cloth), if it doesn't work, you are no worse off.

Is it a hissing sound ? If it is a hissing sound and you can smell ionized air (ozone) then there may be some high voltage leaks (corona discharge) in the High voltage supply coming from the flyback transformer. This happens when there is a path to ground because of dirt dust or spider web, or your surrounding is humid.
