Help! Plasma has red and green dots

damn, so is my 50" Samsung Plasma dying a slow death? It's especially noticeable when the screen is darker. You can see a bunch of green and red alternating pixels. Any ideas on how to fix it?

I dont want to and cant afford to buy another plasma. Thanks for the info guys!

It is probably a voltage adjustment - I have seen it on quite a few plasmas. Mostly Philips brand, but we have had a few Samsungs through the shop for that problem.

There is a Tech tip for Samsung Authorized Service Centers. If I remember they list it as a "diffusion" problem.

If the adjustment doesn't hold, then the panel needs replacement but most of them have been good after the adjustment.

How do I "adjust the voltage"? Do I need an authorized tech here? Any suggestions as to where to get it done for a decent price?

Thanks

Sounds like a voltage problem to me.

If seen this on samsungs before.

Oddly though, it was LCDs that I saw it on.

Thanks

The voltage adjustments are on the power supply boards. It is best to use a Samsung Authorized tech that way if they haven't done it before they can look up the info on Samsung's ASC website, so it is done correctly.

I would say bring it to me, but I'm in Abilene. You can call 1800SAMSUNG and they can direct you to the nearest Authorized Service Center or you can check online.

It is a fairly straight forward procedure, so I wouldn't see it costing more than $100/labor if that is all it needs.

On the LCD sets it is generally a loose/partially plugged in cable - we have had a handful of those that we just reseat the cables and they work like a champ.
