PramitP :

Hello, Welcome to Justanswer.

PramitP :

My name is XXXXX XXXXX I will be glad to help you.

PramitP :

Can you tell me how old the TV is?

Customer:

my tv is about 3 years old so out of garantee

PramitP :

That is what I wanted to know as it seems to be a panel problem.

PramitP :

It is a dark shadow which covers images or do you get only color distortions?

PramitP :

Does it happen on other sources too, like a DVD player?

Customer:

It covers images but at the moment i do not know if it happens when we play a dvd

PramitP :

Ok, this sounds like a backlight problem. There are two possibilities.

PramitP :

One could be a fault in the inverter board. This is the board that is responsible to supply power to the backlight

PramitP :

It has many tiny components on it like capacitors and resistors whose values will have to be checked so as to confirm the cause of problem.

PramitP :

The only other possibility is the panel itself.

PramitP :

In that case the repair would be very costly, infact more than the cost of the TV itself.

PramitP :

So, what I would recommend is, get a service technician to examine the inverter board. It most likely seems to be a problem in this case. You can get it fixed or replace the baord if that is the case.

PramitP :

If you have any other queries then I would be glad to assist you further.

Customer:

nevertheless, it is worthwhile to let it examine by a technician?

PramitP :

Of course it is. It seems to be an inverter board issue. If that is the case then your repair should be done within $150-$180. You can continue using the TV then. But in case the panel is bad then it is wiser to go buy a new TV.

PramitP :

What you can do maybe, if take it to a local service center and ask for only a diagnosis especially of the inverter board. If that is fine then it is the panel. This way you will end up paying only the diagnosis costs which is less than $50 at a local store.

If you have any other queries then I would be glad to assist you further.
