I have a green spot in the upper left corner when watching tv . Is there a repair for this problem?


The spots are caused by errors in the eeprom affecting the optical engine data. The fix is easy but it will have to be done by an authorized Panasonic shop. Call your toll free customer line at panasonic to find out, but I'm sure the repair should be covered under warranty regardless of the age of the unit. Thx

TV issue


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.

LG DLP Projection TV Green/Brouwn vertical Bar


Hi there.

The excessive heat from your lamp has burned one or 2 polarizing lenses.
To replace this you have to pull the optic engine out of the unit and dismantle it.
You will see 3 square lenses in there, remove one by one until you find the burned one.
Then go to ebay and type in hoya polarizing lense.
Buy the 72mm one and cut it to size.

hope this helps.

Light green and pink spots on my hd tv!!!


Hi--Bought my panasonic pt-52lcx65 on sale for $2200 in 8/05. Replaced the lamp for about $300 in 1/08, just prior to Superbowl. Admittedly, this was to be expected after family members watched lots of tv over 30 months. However, two months later the blue spot emerged in 3/08, and red spot emerged 5/08. Set looks decorated by a Andy Warhol or Van Gogh wannabe. I'm looking for a fix it solution. Dr. Bob Heiliger, Lebanon, OH.

Light green and pink spots on my hd tv!!!


Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.

Green spot on the middle of screen.


If the spot is perfectly round then most likely you have phosphur burn on 2 of the CRT's. If it uneven then maybe it is a spider who has made his home in there (not uncommon as it is warm and dry which is what they like).As far as cleaning goes, don't use standard glass cleaner as it will damage the screen. Use warm water and a soft towel, or purchase glass and plastic cleaner which is ususally a foam type spray.
