    So your saying that i need to replace the T-con board and that will solve my problem??

  • hotrod6 Oct 16, 2010

    This set has 2 backlight inverter boards right? They should be good since the backlight is lit right? I dont see any bad caps on the PS board.. I found a T-con board so if i replace it it SHOULD work right?

  • hotrod6 Oct 16, 2010

    Thats great!! Could you tell me where that board is located? I see the main board and the power supply but dont see that board.. If i can locate it i will accept the answer as you have been VERY helpful!!!

The most obvious board is the T-con one, the one that converts the raw data image from the processor (which works, since you have sound) to the actual data displayed by the LCD pixels. It will be reasonably priced, around $250 for a new on and $150 for a SH one.
The problem will be in finding it - i have been unable to locate one for you in all my bookmarked parts sites.

    Yes, that should be enough. But to be absolutely sure the tv must be tested.

  • Azrael SRL Oct 16, 2010

    Yes and yes. The only other part that could have caused the image loss is the processor, but if it would have had a part of it dead then the rest would have also malfunctioned - but you get sound - so yes, replacing the T-con board should fix your tv.

  • Azrael SRL Oct 17, 2010

    The LCD panel should have some very wide flat cables plugged into it - these cables come from the T-con board. Here is a document to help you with that http://www.scribd.com/doc/25276757/E4095...

It must be the picture tube. How old is the TV?

Lcd tv screen just went black, stiil have sound can it be repaired and is it worth it


There are a number of reasons for the screen to go black. Basically, the inverter section has failed. This can be fixed either by replacing the inverter board or repairing the board. Replacing the board, while easier, is more expensive. I would suggest that you get a detailed estimate from a shop that performs component level repairs. They should be able to determine whether or not the board is repairable. Without seeing the board and taking measurements inside the set, I can not make that determination. Armed with the estimate information, I should be able to provide you with options.
