Facing TV Problems? Ask a TV Technician.

This is a very simple approach.
(Please click on high lighted words)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. GOOD luck friend
