The tv was working fine until this morning, then the picture went out but the sound is still working.
TV is only 3 years old, no real electrical problems
If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it. Good Luck.
