Sony KDS-55A2000 Yellow Patches in Picture

[Ltank]

I turned on my TV tonight and noticed yellow patches or blotches in picture even on the menu. Is a SXRD Type. Is has the three liquid crystal generator setup. What one of the three would cause this or is the whole block one assembly? Thoughts or suggestions?

That is blue module failure. Very common wih these sets from what I have seen. UV light from lamp assembly (especially if aftermarket bulb used) damages the module.

Right after I posted it, my wife asked. Have you tried turning it off and and back on. I said no. Strange thing just to appease her, it worked! What are the odds of that! I know it will probably back but now at least I have a heads up on the problem. We just came back from Church. Praise the Lord that it working because we are having to buy another central AC unit this week.

I have replaced the bulb twice before, It uses a clear projection bulb like a DLP projector. It had three Liquid crystal devices I beleive. I just located and downloaded the Service Manual. I am sure it will be toast soon if the modules are unobtainable.
