No picture on my lg50pc1d plasma television

SOURCE: vertical flickering color lines instead of pictures

Soory man there is no deflection yoke or vertical output IC in a plasma TV set.LOL This person has a problem with whats called the substain power supply or bad caoacitors in the main supply. there is also a possibility that the set has a bad tuner. Only performing test on the set will determine the problem.

If it is only one pixel in width then you are most likely looking at a panel issue. In most cases a bad panel means it will be cheaper to replace the TV. Try resetting the TV by unplugging for 2 minutes first.

The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

very possible the YSUS board is going bad .If YSUS is going bad .I would also replace XSUS board since they are same age..Also whenYSUS is replaced make sure you make pot ajdustments as old YSUS and also with XSUS board

The LCD Panel failed. There is no easy fix but try to get the T-Con board to fix the issue. However, this part is usually only available with the whole LCD Panel. This is usually the most expensive part in the TV and the whole TV needs to be taken apart to replace the panel.

Might be economically viable if you can find a place that carrys the T-con but Dynex parts are usually hard to find. The LCD Panel part alone will exceed the cost of the TV.
