If you have a sound and no picture, especially if it flickers then it rules out the main board and CTRL board being bad. You will want to replace the Y-Main board, but when you replace the y-main board you should always replace the upper and lower ybuffer boards because they can short out your new Y-main board.

My panasonic model #TH-50PX75U wont turn on, it powers up but the led light stay on not blinks any time.


Unplug the power cord. Press and hold the power button for 30 seconds, repeat. Plug it back in and try to turn it on.
If this doesn't work, it would be time to call in a repair tech. Is the TV still under warranty? Extended warranty?

Just yesterday, my Panasonic TH-50PX75U HDTV Plasma Television has only the lower half displayed. The upper half "flickers" but for the most part, dark grey/black. wtf


There are several possibilities here. Four different boards are involved in the horizontal scan of a plasma tv. The most likely order of failure for what you describe is; SC board, Su and SD, and finally the SS. These are Panasonic's names for what are more commonly known as the Y Main (or Y-Sus), the upper and lower Y buffer boards, and the Z main (or Z-Sus). Sorry I can't boil it down any further for you,... would have to measure voltages, etc.

Are you using component video cables? If so, check that these aren't loose on either end. Next I'd consider that whatever video cable/input might be bad, and switch cable or cable type... i.e. switch from component to HDMI or vice-versa. Then change up the source (cable box versus DVD player). If you're still seeing blue at this point, the TV internals are the bad.
