Hello,
it possible that the problem is the the TCON board, you can try websites Shopjimmy.com,Ebay.com to buy a refurbish board for the replacement.

Also note that
The T-CON (Timing Control or LCD controller) board (on the LCD panel assembly). It transfer the universal image signal of TTL and LVDS signal to specific TFT (Thin Film Transistor) LCD.
This is the interface board that talks to the Logic board and the LCD panel to produce pictures on the screen. White/gray glowing screen when it fails or not getting the voltage from the logic board (the 5 or 12vdc is supplied by switched transistor on the logic board). Notes: T-CON board is mounted under the metal cover shield.
Common failures:
Scrambled pictures, Lines, multiple pictures, color smears/blotches, rolling pictures after warm up.
Blown surface mounted fuse.
No pictures, very dark screen almost like there is no backlights.
Hope this helpout..

Vizio tv repair picture blurs and darkens for five seconds and then goes normal for five seconds and continues this cycle. i changed the tcon board and no change.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

You cannot test the T-Con bd with a meter. However if you have the luxury of having another same model tv, you can install the bought T-Con bd and see if it is good or bad. Since you said the Menu and channel flashses, then I would replace the Main board.

Sony bravia LCD KDL52 TV: blurred picture with color bands


It is most likely the TCON board (located at the top right against the LCD panel). When these boards have problems, they can act up when cold or warmed up.

You will want to check with any extended warranty company you might have, or Sony's part website for the availability of the TCON board.

The problem here is, sometimes those TCONs are not made available separately and need to be replaced with the screen.

If you have to replace the panel, buy a new tv. You'll save yourself a costly repair.
