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.

The most common cause for the loss of picture is a bad Horizontal Output Transistor (HOT). but I would suggest you get a detailed estimate. I think that this would cost you about $60.
The horizontal lines means the vertical amplifier or deflection system has failed. There are over 100 components in this section and any one of them, or most of them can be at fault. However, the most common failure is the VOT or vertical output transistor (which is often buried inside a chip).
The repair will cost around $250 plus or minus.
FEW TROUBLESHOOTING STEPS YOU CAN TRY:
ONE: Do a hard reset (just to make sure there is nothing in the coding that is fowling things up). Unplug the power cord; leave it disconnected for 4 hours. That will restore everything to factory defaults when you power it back up.
TWO: Do the "whacking test" by banging your fist on a few strategic places to see if there are any cold solder joints or loose wires acting up inside the set.
If the above steps don't solve ur problem then I suggest you to go for a repair..
