Hopefully someone can help me out. I have a Panasonic PT61-LCX65. I bought this tv cheap because of the "color blob" problem these (and other panasonics) have. I had been searching for awhile to find the eeprom correction tool (LSUQ0100) for this, but could not find it, so continued to use it as a gaming tv.
About 2 years ago, the bulb went out and I replaced it with a bulb from ebay, and it was back to normal. (working, but with color blobs) About 6 months after replacing the bulb, I started to notice tiny blue dots appearing on the screen. These dots are about the size of a pinhead, and I figured it was the eeprom problem getting worse. Long story short (too late) I just acquired the LSUQ0100 and fixed the color blob problem, however the blue dots are still there.
So today, armed with the service manual, I decided to take apart the tv to see if it was maybe dust on the blue side of things in the optical engine. However, when I removed the bulb, I noticed tiny little pit marks all over the reflector portion of the bulb, and the backing behind this reflector is blue. I also noticed on the bottom portion of the actual glass tube inside the bulb, a small heat bubble that itself looks like tiny air bubbles.
I guess what Im getting at here, does anyone know if a heat damaged bulb that still works will cause this blue dot issue? Using logic, it would seem that the bulb is the culprit, but maybe not. Anyone know or have any ideas?
thanks in advance
btw...to clarify..this is entirely different from the "color blob issue" I have actually fixed that and all "color blobs" are completely gone.
