Why does the screen turn white after 10 minutes?


Probably the t con board have problem. the power regulator ic on the tcon board make this problem. As ist an smd ic you have to go for a new tcon board, because its not possible to replace the ic with normal soldering irons. you need smd rework station for that purpose. And also on more thing in some tvs the t con board is integrated to the lcd panel. if so its not possible to replace only the t con board , you have go for a fresh lcd panel. it would be a costly repair. because the panel is the costliest part of the tv. Any why check the video to understand which one is the t con board. if you find one in yours then try to replace it with new one. hope your problem will solved

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..

LNS4692D - TCON Board (seems there is a systemic issue)


You have to be very careful with the flat ribbon cables and be sure not to have an electro static discharge to the board while handling it but it is not that difficult of a repair. It is the board that is located at the top center of the back of the lcd panel. Depending on your problem, eg. line in picture, no picture with backlight.... it unfortunately only fixes about half of the units. The other half need lcd panels which are very expensive. hope this helps.
