Question about Televison & Video
I have a samsung 51 inch plasma Ps51d450a2m , has been working fine for about 6 months . All of a sudden I have red dots on dark part of the screen , they come when the screen goes dark and disappear but come back any time screen is dark . Any idears
Usually either the main board or the power board--if set is 6 months old---no warranty?

The driver board is going bad it sounds like and if you do not call up and get it fixed under warranty, as it should still be under a warranty, then its going to be a nice hefty repair bill. Good Luck Ps Please dont forget to rate this thread

Did you get this problem resoslved? I had the same issue a few months ago. I tech came by and took my TV to the shop, a few days later he said it was fixed as they needed to make some adjustments.....The TV has been fine up until a week or so ago and now the red dots have appeared again. Was wondering what happened to yours.

You can get rid of the red dots by adjusting the V-scan voltage down, it's on the panel sticker inside the unit, you can find the test point on the DC to DC pcb, and the adjustment pot is on the same board, lower it as you watch the screen and only lower it enough to rid the screen of the dots

I have been having the exact same problem. TV on for 30 min with terrible static, then all of a sudden it is perfect again. I've also inherited a bit of a humming noise from the tv as well. It was suggested to me in this forum to have a tech come and adjust the v_scan and v_set settings down a few mhZ. No idea what this means, but I assume it's a power setting and the tech will be able to take care of this. I will post my results when i have the tech in.

I had a mass/earth cut and it does that on my screen. What I do is I plug it where the electricity is ok
