Panasonic Viera TH-42PX80U Plasma TV Logo

White dots floating across screen of Plasma TV.

42" Panasonic Viera Plasma Tv. It has these white star-like dots that float across the screen from left to right. Just started doing it out of the blue. Even when the cable box is turned off and the tv is on they are still there on the black screen so it's not the cable signal. Tried turning it off and back on but they're still there. Any ideas?

Turn everything off and disconnect from mains.
Wait a few minutes.
Disconnect HDMI cable.
Turn on TV and DVD.
Connect cable.
If this does not work use a cable of different spec.
I had the same problem and now mine works .
Good luck.

1.You may have the magnet of a speaker too close to the TV.
2.Turn off other electrical devices in the house one at a time.
3.Faulty cable.

SOURCE: plasma TV with vertical lines

Help! My Plasma by Magnavox is putting black verticle lines on the right side of the screen - comes and goes - and I replaced the entire Direct TV-HD unit - wires, everything - and had TV company repair - and it still came back. The TV repair refuses to take TV back because it does not show up when they come. Although I videotaped it and showed them which has the date and time - they still refused to take it - and tried to get me to sign a paper saying it was working while they were there - which of course I refused to sign - so they left and nastily said they will not be back-find someone else. I still have the lines - and do not know what to do! Can anyone help?

White dots when Panasonic plasma TV turns on disappear after warm up.

White spots or dots showing up on your TV's screen could be the result of a bad or damaged processor or due to some overheating occurring the summer time or cold weather temperatures during the winter time. TVs can be affected by electricity surges or spikes as electricity supplies vary throughout the year. Or power outages and brown outs and black out can also cause spots to be on the TV screen too.

Try the following troubleshooting steps.Check power cord and power outlet, possible light switch problem.
Check if you TV savy check the P board if the P board is not good check the fuses on the P board.
If the P board is OK check the A board.
To check these Unplug the TV , Disconect A5 A6 and A7 on the A board and plug the TV in and see if you get a white screen if this is the case your P board should be OK.
