Green and Blue spots on screen

Those Rear LCD TVs get bad light engine on some. Causes fuzzy spots size of quarter. Or sharp small bright spots looks like road map or 'stars'. Need new/rebuilt light engine.

either panel going bad or power supply voltage set wrong you need a good tech to help ya

This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.

I had the same problem, first a blue spot then a green spot showed up. I contacted Panasonic Customer Support. They sent someone out and they fixed the TV for free. They reprogrammed the EEPROM chip in the TV. It is a defect. My TV was almost 4 years old and out of warranty.

So long as it is not happening by something you have done. It will be fixed free of charge. Call them, it solves the problem.

Sounds like a possible Bad Light Engine hopefully you have a extended warranty otherwise look for a costly repair

You have a bad optical block, the block has a 2 year warrnty but you will have to pay labor to have a tech change it

I have a similar problem, what is the fix?
