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
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.
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!!
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.
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.
