    Hi, so I took apart the unit, wiggled every cable, tried the tv, same problem, after the tv is turned on for a few minutes the left half of the screen starts changing colors in vertical lines which match the background colors playing on the tv. This continues for a moment then the left half goes completely white. I tried disconnecting and connecting the wires again. Still nothing. Anymore ideas??

Hi,

OK I would like for you to open unit and in the middle of the panel is the T-CONN board, it has the LVDS cable going to it and the main board. First try to wiggle the LVDS cable to make sure no loose connections while set is on. Next disconnect LVDS from T-CONN board make sure to not let the cable touch any metal turn set on and see if screen lights up and with a clear screen. If not OK some models won't let you check this way. But if it does the panel is not faulty it is OK, LVDS or main board or T-CONN issue. So let's hope it's the CABLE, LVDS is loose. If you isolate inside the unit you may find your problem much quicker.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    Thanks for your response!!

    As it was not OK, this confirms a hardware failure. If you have experience in repairing electronics, could read schematics and would be able to take all the precautions, i could provide you with a link where you could purchase a cost effective service manual and i would provide you few pointers how to go about troubleshooting further ( advance ).
