Hello, I have somewhat of a strange issue with my new Panasonic PX77U plasma (the costco model). I've tried looking for info, but its a difficult problem to search for. Here goes...

Occasionally (so far just twice), I've noticed a stuck white pixel at the very top of the screen towards the right corner - but only on ESPN HD. When I change channels, the pixel goes back to normal. Flip back to ESPN HD, and there it is - on the top row of pixels. When I adjust the aspect ratio while on ESPN HD, the white pixel adjusts with it. That led me to believe it was a broadcast issue - however - both times I tried turning my tv off and on quickly, and the white pixel vanished.

I've never encountered anything like this, and I don't know enough about TVs to know where the problem is (whether its the tv, cable box, broadcaster). Has anybody experienced or heard of anything like this?? Any help would be fantastic. Sorry this is so long, but it seems like a strange issue to explain. Thank you!

Edit: After looking at it again, when the white pixel shows up, the entire top row of pixels left of the white one are near black. Turn the TV off and back on, and they all go back to normal. Again, they only do this on ESPN HD...

So does that mean I'm the only person who has ever experienced this?:(

A truly stuck or dead pixel would not be stuck or dead on only one station. A couple of thoughts: First you can get either test discs or even an inate program to the plasma on some that will allow an all white screen. That is useful in identifying any dead or stuck pixels.

Also, you may have an overscan situation, althought based on the pattern, it isnt likely. Lastly and as an aside, some DVD players will "CROP" video signal data. For instance, the Denon 3910 inately has some pixel croppping issues that are known. Perhaps your cablebox or card has this tendency ( if you are using one or even a DISH type receiver) based on how espn is sending their info, this may become more noticable on their stations.

Bottom line..if you dont see this on DVDs or consistently, its unlikley to be the fault of your TV as far as a dead or stuck pixel.

My last thought is that if ESPN is transmitting if you will in HD resolution but your display doesnt match, you may be seeing the result of downscaling ( or upscaling)-- this really shouldnt happen as data should be upscaled or downscaled to fill all pixels....but ya never know.

Thanks for the response. Perhaps I could stop by charter to switch out my HD cable box and see if the issue persists. Its just strange since it comes and goes. Right now my only solution has been to turn the tv off and on again, so maybe I'll get somewhere with charter. Thanks again.
