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

Projecting in green.


lamp may be on it's way out. if the mercury vapor burns at a different temperature than it's designed to, you will get a different color. also check the lamp for bulges, black spots or fogging. if it has any of those, replace it. if the lamp is ok, replace the ballast.

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.

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 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
