Here is a better video of the problem. The tv has developed green spots on the right and top of the screen. There is also a blue spot near the center. This is a 2006 Panasonic rear screen projection t

Hello, inside the set there is an optical unit with 3LCD panels. Somehow the dust particles came into your set and now the dust is all over the optical unit and 3LCD panels. Only way to solve this issue is to clean the dust. Please contact your Sony dealer. Best regards, Arpi

You have a defective light engine and if you call Hitachi's customer relations department at 800-654-7013, they will give you the names of some dealers in your area to come out and confirm the problem. Once the tech tells you it's a bad light engine, Hitachi will send a brand new light engine to the dealer to come out and install. If you're not under warranty Hitahci will cover the cost of the part (around$1500) but you will have to pay the install (runs $200-400 approx)

Our TV was just fixed and it didn't cost us anything. Our TV was 2 years and 2 months old and out of warranty. After several calls to the customer relations department they agreed to pay for the labor too. If you don't get satisfaction with one person call back and ask for a supervisor. My husband was very polite but firm that he thought this should all be paid for. Our tv was fixed yesterday and it is not just like new. Good Luck

Hitachi has not recalled this (although they should) but they are replacing it. Don't get discouraged if when you call them the first time, they act like they have not heard of this problem. Just follow through and have the set looked at and they will replace the part...you just pay the install. Once our light engine was replaced, the TV is like brand new. Good Luck:)

(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 disappear....no 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 this....you don't see that very much these days!

Thanks,
Chris

I do not have good news for you---this model is prone to the optical light engine going bad---usually a red oval area in the middle of the screen----I have also read that there are now several class action lawsuits related to this problem in this set. You can Google the model number and you will set what I am talking about.

I have replaced several light engines(called an optical engine) in this model--both the 50V500 and the 60V500 have this problem.

The last time I checked the optical engine wholesaled for about 600 dollars and is major labor to replace--I had someone else here ask me about this set---He was in Canada and the first time he called Hitachi he was told they were not aware of any problem--after posting here with me he called them back and someone admitted they knew about this but had been told not to say anything or admit any problem---thousands of these sets all have the same problem.

Clearly the set is not worth a 600 dollar part plus labor---considering the cost of new sets, but the only other option you have is to try to connect with one of the several class action lawsuits---I found them by typing the model number and lawsuit after it on Google.

I know I am not giving you good news but I know this set.

It is better to contact your local Panasonic authorized service center. This issue is easy fix by connecting special Panasonic-issued tool (programmer) to restore corrupted file in EEPROM inside of your TV. Rear cover have to be removed, tool plugged in service socket and 15 minutes later your screen will be as good as new.
Without this tool - I would say it's impossible unless you have experience in hacking memory devices. And still got to find original file and download it into EEPROM.
Good luck!
