No picture but sound

Plasma is 2 years old. Turned it on today. Have sound on all channels, but no picture. Can't use menu solutions because the screen is black. HELP PLEASE. Too expensive to fix at this point, but hoping it's a programming problem.

Re: No picture but sound

I believe this is an expensive part to fix. If you interested I might have someone that would purchase the plasma from you.

Our Panasonic 50" TH 42PX75U

well it sounds like something fried inside the tv. In my experience, this sounds like your y-sustain board went bad. it could be your video board also. considering todays value of the 50" panasonic plasma, it will be cheaper to replace it, unless you are willing to spend around $300 to get it fix at a shop.
good luck

I turn on my 50PF9956 get sound but no picture. For 2 weeks before it started taking longer to get the picture. I tried the menu with nothing

The plasma picture tube technology lasts only 24 months before it burns itself out, requiring a new
plasma picture tube. The LCD and LED technologies do not suffer from this short life span.
If your Philips 50PF9956 is over 2 years old, you've got all the use your plasma can give.
Fix: new plasma display - the electronics controlling the plasma display are most likely fine - just
like the electronics providing audio to the speakers. Your set's only problem is a burnt-out display.

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.

Vertical colored lines on screen-no picture

It's definitely possible. I'd have it checked by a repair center for something like this.
