We have a yellow tint in the picture, it is worse

I have a older 2006 SXRD rear projection TV. I had the same problem after the TV warmed up this yellow tint started in the corner and crawled its way down the TV. It turned out that Sony had a recall on the optic block of the TV. If you replaced the Lamp and adjusted the color this kinda sounds like the same problem. Here is a link explaining it. In this article it shows up as a green haze and blob, but in my TV it manifested as a yellow tint.

Hi,

There are 2 common causes of a Green Tinted Picture in Sony 60A2020 and other Sony LCD Rear Projection TVs:

• HD cables from cable box or other source faulty or not tightly connected.
• Optical Engine Failure.
  This link shows what some Sony Optical Engine Faults look like.

Reset the tv back to factory setting.By unplug and replug the tv an hour later.This should work,not than ur tv Tuner board it dead.

Hi:
Replace you lamp or have it replaced by a technician. Lamps are only good for about 6500hrs depending on use. Thats about close to 3yrs.
