    I have seen other postings of this problem and many propose a solution of an eprom upgrade. When I asked Panasonic about this directly, they said they were unaware that an eprom upgrade would solve this problem.

    Are you saying that this problem can be fixed without the help of a technician? Any chance of messing it up more?

  • GPHL Sep 13, 2008

    I have the same problem. It started as one green spot ... now it is several spots ... each the size of a baseball. The spots appear and disappear depending on the color of what is being shown on TV. Does anyone have experience with this suggested fix?

    My PT-44LCX65 has a baseball sized pink spot in the center of the screen. TV is two years old and I replaced the lamp assembly this week when the lamp light came on. the spot is still there.

    My 52" PT-52LCX65 hdtv has a blue, red and yellow spots on the screen that began appearing roughly in August, maybe July of 2008.  The only repair alternatives I've been able to find is to have the light engine replaced for a cost near what a new tv would cost.

    Don't understand why the company doesn't step up and take care - GOOD CARE - of customers.

    I have had this problem twice now since I bought the TV just over 2 years ago. Fortunitly I carry a sears extended warranty on it so I was able to make my problem theirs for no additional charge. Last year they replaced the entire lamp engine, very costly. Almost 1 year later it happened again, this time panasonic told them it was a simple eprom update which they did yesterday and the problem is fixed. So the EPROM update does work.

  • shea_468 Dec 01, 2008

    i have the exact same problem. there are red lines and green and blue spots all over my tv and it is only a little over a year and my warranty is up.. is there anything that will fix this because i went back to the store i bought it from and they said that they couldnt do anything..any suggestions

  • Anonymous Dec 10, 2008

    Service Shop just told me that in 80% of the cases, the LSUQ0100 will solve the color spots issue. Sometimes it can be the a damaged circuit. Cost is $175.00 for the visit, and the EEPROM update procedure is usually $150.00 more. However,they said Panasonic is extending the warranty an extra 12 months for this.
    However I purchased my TV on mid 2006, which makes it 2.5 yers old.
    The problem seems to worsen when you crank the brightness and/or sharpness up.

    Lucky me, I purchased an extended 3yr Sears warranty. They'll come in 2 weeks to check it out.

    If you purchase a Panasonic, add the service plan.

    Same deal. 3 pink spots, toward the middle-right side of the tv, and going towards the lower right corner of the tv. It gets worse depending on what colors are being broadcast.

You really need to be persistent. I went on the Panasonic customer support webseite and started a web exchange. The first two attempts ended with "call your local authorized service tech" , etc. The third time, I described the prolem again and asked if the authorized tech would have the tool to fix the eprom if that was the cause of the problem. They finally gave me a name for their scheduling department and said they would pay for the diagnosis. I was pretty happy about that, but even happier when they said that this was a known problem and they would pay for the repair as well. They scheduled a service call. The techs came and fixed the eprom error with their tool within 1/2 hour. That was about 5 weeks ago, and all looks good so far.

I had the same problem and based on this forum, I phoned Panasonic service 1-800# and
mentioned the correction tool: LSUQ0100.

Even though my TV was purchased in Feb of 2006 and well out of the warranty, they put up no fuss and sent someone out from a local authorized servicer for NO CHARGE ! My two green spots and one red spot disappeared in 15 minutes.

The repair guy said that this is a design flaw. Not really a 'break'. That is why the repair is free.
Good luck.

I have had a green blotch for a long time and have contacted support. They tied me up with Emails and faxing my model numbers and all that good stuff till they just made me give up. All I got to say is FU Panasonic, I'll NEVER buy another stinking pile of monkey poo TV from you again. I've bought your stuff for years and this has made me sour as hell and totally pissed. YOU try watching a blu-ray with a frickin' green blotch on Neo's face!

My rear projection TV has color spots in the picture, most noticeable on light color picture

What is the make and model of TV. If it is a Panasonic that has different colored spots such as pink, blue etc. Then you need t6o contact Panasonic as this is a memory reset that they have to perform on the LCD driver board. Other brands of LCD projection sets that have spots that appear all over the screen mostly on white back rounds are almost always dust that has settled on the LCD panels. This requires a technician to clean the LCD panels if possible.

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

For the spots....

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 4 years old and out of warranty. They came out last week.

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.

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.

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.

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

(Yes, this is a cross-post from another thread...I just wanted to help everyone on the various threads on this issue...please do not flame me)
Ok...once and for all I will explain the fix (in detail...which has been missing)...

1) Firmware updates do not fix this problem. I had this problem, and updated my firmware to the latest versons without success. Also, cleaning the light engine (or any other part) does not fix this problem. If you cleaned your TV and your problem disappeared, you had a different problem.)
2) This repair requies a special tool from Panasonic. The tool is part number LSUQ0100. It is light grey in color, and is roughly 7" x 5" x 1" in size. It has diagnostic lights on it, and a button to press to start the procedure. This tool is used to reprogram your EEPROM. Again, this is VERY different than flash upgrading your firmware.
3) To repair the TV, the repairman must remove the lower back of the unit and plug the long, 5-wire connector (5 individual wires terminated to one female connector end - reminds you a bit of an old-style CD-ROM audio cable used in computers) into a male recepticle on the light engine.
4) The procedure takes roughly 6-7 minutes to complete. The TV remains on during the procedure (yeah, I was a bit surprised too). About mid-way through the procedure, your colored ball-shaped blotches will just on-screen progress bar, no bright flash, the spots just disappear in the blink of the eye.
5) CALL PANASONIC!!! They are standing behind these TVs, and are covering these in-home repairs free-of-charge - EVEN IF YOUR TV IS OUT OF WARRANTY. Mine was out of warranty by over a year. The Panasonic rep was very kind, but did explain that this is the only repair for these TVs that they will cover out of warranty, as it was a defect in the manufacture of the unit - all other repairs are at the expense of the customer.

Good luck to all - I hope this helps some of you!
Cheers to Panasonic for standing behind their products like don't see that very much these days!
