I've been reading this thread for some time now.
A few months ago, I was able to get my hands on a 70" Qualia.
It has been working just fine, looks great...till yesterday.
Now I know the symptoms of the optical block issue...the discoloration, green blobs, etc.
Yesterday, my set wouldn't fire up.
The power/standby light would continue to flash, audio was there.
After powering down a few times, the bulb finally fired, but, the image was very dark, I would say 25% of what it should be.
The lamp light is not on or flashing, and it takes a few reboots to get it to fire.
Is this just a bulb issue or something related to the optical block?
Awaiting your expertise
