Screen has developed several patches but only on blue images

The color static, if we are talking about the same thing, is usually a digital signal interference. Check cables, and digital converter if used.

I've also had a popping noise on our 50" LG plasma TV, however the picture has not gone, but has turned grainy and colors are weird. Can this also be a blown fuse or a more severe problem (ysus board or similar)?

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

hi i have replaced power controls boards in more than a few of these & this needs to b done by a expert .

Its either the XYZ circuits, power supply, or bad ESR conditions starting to develop. Have your local shop repair it for you....

The set is 4 years old, and usually problems in Plasma tv's develop before then......

This is a problem in one or more boards in the TV.
If your TV is still under warranty please call Samsung to get if fix at not charge.
parts for your tv are not cheap and labor is not eider.

Do you normally leave this set on a specific channel...such as CNBC or BLOOMBERG tv...etc that maintains a regular scrolling image???

If so...on sets that are a few/several years old...the projection tv screens can develop what's called a "burn" or "burned image" on the screen...similar to wearing a path in your carpet from heavy traffic areas. Newer models do not have this issues...but many older ones do.

Philips 50 inch plasma tv no video but has sound

I have a samsung 42 in plasma television which is three years old, it has a blue flickering light to the right of the television, sometimes can see some at the top in the middle, hope you can help with this problem, is it repairable.

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.
