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


Posted on Jun 04, 2008




I also have several yellow blobs on my TV (PT-50LC14). It is due to a burnt polarizer filter just past the blue filter for the blue chip. This TV is a three chip design with red, blue and green chips.
I am currently trying to get a new polarizer filter from Panasonic.

Spots all over the tv panasonic pt-61lcx65

If they are large colored circles behind the picture scenes, mine had it too. Fix was as simple as service technician plugging into the EPROM and loading a software update. Picture then was better than day1.

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

Eprom correction tool is used by servicer to remove spots. If he calls Panosonic tech line and mentions Fuzzy spots they will give him and auth number and pay for the service.

Pt-52lcx65 52 in.

call panasonic customer a claim....problem is most likely that the eprom needs to be reflashed.....i contacted them several weeks ago, told them my problem which was 5 baseball sized colored spots, 1 red, 2 blue and 2 green. they had me perform a couple of tests using a dvd. when i reported the results they set up a service call with a local authorized repair shop. results were amazing. reflashing the eprom took about 4-6 minutes. in addition my brilliant color returned to the set as well as another problem of neon images going away. this was paid for by panasonic. my set was 2 years over warranty. panasonic has issued a service bulletin on this and are backing up these units.
hope this helps, i am quite satisfied with what was done.

Spots on picture

I had the same problem. Panasonic is kind of a pain about the whole thing. You have to find out who your local Panasonic repair place is, tell them there is a service bulletin and they will get on it. You must be diligent! Do not take no for an answer! If it comes down to it, and the repair shop won't do it for you, then call Panasonic and endure a loooooong wait time. Trust me though...this is the issue. Once the eeprom gets fixed/updated/whatever, the picture looks amazing! Good luck.

PT44LCX65 Has spots and Haze

Panasonic has a fix for this problem. No need to replace the light engine. Just have a service tech do an "eprom upgrade" - Fixed mine.

Panasonic PT-52LCX15 green spot on screen

Easy fix. I had the same green dot problem and I removed the front panel (no screws). In the center is a panel that has two screws. Remove them and pull the cover off. There you will find the projection bulb. Do not clean the bulb but instead the base. Use a damp cloth to wipe the dust off the black disk (the base of the projection bulb housing). Apparently the dust through static electricity may cause enough magnetism to distort your picture. Hope this helps.
