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.

This tv is a LCD projection it has
a red blue and green LCD pannel that the light shines though The green one is bad. Comon problem for these set.

Call panasonic. They have a Tech service Bulletin that adresses this problem. They will only sell the customer the device that fixes this problem and they will quiz you to make sure it will fix it before they sell it to you.

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine.You can find it here: http://www.discount-merchant.com/PANASONIC-521A2C52-p/1177904.htm Have a blessed one!

Hi,
I'm afraid, it is problem of optics unit block (light engine), there are 3 LCDs red-green-blue for color picture formation and blue LCD sounds bad, please call local TV tech for fix.
Thanks.

PANASONIC..PT-52LCX15. STARTED TO A LIGHT COMES ON THE SCREEN. THEN TWO LIGHTS. FINALLY TV DONT COMES ON. I PUT ON THE TV, AND ON BOTTON START BLINKING AND TV DONT COME ON..I TAKE OUT THE TV LAMP..IT LOOKS GOOD NOT BURN. SHOULD I REPLACE IT??

There are many causes for spots on top of an LCD rear projection tv, you are probably in the first two cases, both require part replacements and repair job.

If the spots are faint blue, green or pink shadows, then it can be a problem with the anti polarization panel placed on top of the LCD.

Similar spots (colored shadows) may be caused by a problem with the light engine, in that case the fix will be expensive.

If the spots are bright lights, like an aura, that is a problem with the color wheel.

Problems on the light tunnel can cause static gray shadows.

If the spots are static dark stains than that is lcd liquid, the LCD panel must be replaced.

I had about six green spots and two blue spots about the size of baseballs. Panasonic came out and fixed this for me for free!! They said they "reprogrammed an eprom". I bought the TV in Nov. of 05 and this is Jan 09. Go Panasonic!!

I received a new blue polarizer unit from Panasonic. I installed it and it fixed my problem!!!
