I have a 50pf9630a_37 Philips plasma tv. the top third and bottom third of he screen has pixelated distortion but the middle is fine. I'm trying to determine if the TV is worth saving.
Optional Information: Make: Philips Model: 50pf9630a/37 Already Tried: Looked for blown caps.
Thanks for the question!Does the same issue occur if you use a different video source like the DVD player, VCR, game console, etc.? Or just on the cable programming?Best,Dan
yes - it even does it when I just am in the internal menu mode.
Do the distorted areas blend into the good area, or are there well defined edges in between?
There is a fairly well defined line - the tp third distortion is consistent across the entire screen. the bottom distortion is not nearly as complete. But they both have a distinct line where they meet the middle third where the picture is clear.
Any way you can get me a picture of this? Email it XXXXX@XXXXXX.XXX and they'll forward it to me.
Okay give me a few minutes
Ok.
OK I sent the picture
Were you able to see it ?
They haven't forwarded the photo yet, but I will let you know as soon as I see it.
That is a picture of the Philips Menu screen
Ok, at this point we should go ahead and remove the TV’s rear panel. Now stand behind it and find the scan drive and the sustain board. They are on the left and right hand sides, respectively… large boards with heatsinks attached.Now, turn the TV on (so you can hear the audio) and let it play for 30 minutes.Now touch the heatsinks… are they all hot?
Yes they are getting hot
Ok. In that case, the most probable cause of the issue you're seeing is a defective plasma panel. Typically, the root cause is cold or broken solder joints on the panel itself. This is not reparable. The panel would need to be replaced. The bad news there, is the panel isn't available anymore... and even if it was, it would be far too expensive to consider replacing. Typically $1000-$2000 for your model.Sorry to bear such bad news, but I hope this helps. Let me know if you need anything else.Best,Dan

Allen,Just checking in. Did you decide to replace the TV?Best,Dan
yes - I just dropped the dead one off at Best Buy to their recycling program - I got a Sony 3D 55" for about 1500 and I added the extended warrant and 2 pair of the 3 D Glasses - total was about 2,000
Excellent! I'm happy to hear you're all squared away. Don't hesitate to let me know if you need anything else.Best,Dan
