SOURCE: 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.

Good day.
If you already replaced a new inverter board and T-con board and the problem is still there.Try to play the video on the DVD,if the video is OK check the cable connection and try to run auto scan.
If the problem is still there check the input supply of the system board or main board it should have 5vdc and 12vdc,if it is OK replace the system board.
Review this manual page 4-1 abnormal display http://www.scribd.com/doc/36875894/Olevia-232-S12-SM
I hope this solution will be helpful.Thank you for using FixYa.
yes it could be a t-con board but could also be a 12V power supply output failure. The Video processing board, and LCD panel uses 12V
