The color is distorted on the lower left hand side of the TV, or maybe distorted is not the correct wording. It looks like there is a yellow haze in that corner...

The model of tv you have is very common bad light engine, because you mention there is yellow haze on lower left corner, if you need more help please feel free to call me anytime, i live in mesa az at 602-810-7149. And is not worth to get fix because the L.E. will cost you between $500.00-1000.00.

The yellowing of Sony’s KDF-60WF655 rear projection is a problem with the SXRD optical engine. This turned out to be a big problem on many of the SXRD TV's. Sony actually had a class action lawsuit that covered the optical engine for 5 years. My unit was replaced in June of last year (2009) about 1 month before the coverage ended. My unit had a bad yellow streak on the right hand side. Sony no longer covers the cost of replacement, as the class action suit has now expired. Sorry for the bad news. Its not clear if a new optical engine will suffer the same fate after a few years. Sony’s rear projection TV's are amazing and the picture rivals many of today’s LCD's and Plasma's. Any authorized Sony Tv repair shop will no exactly your problem and will be able to give you a fixed price to repair.
Hope this helps

Yellow spot in lower right hand corner

You have pretty much narrowed it down to being a bad optical block. This isn;t good news, since the optical block is probably the most expensive part in the set. Your best bet is to contact Sony customer support to see if the will allow some kind of accommodation for the repairs. Sorry for the bad new; hope it doesn't effect the rating you give me for the solution. Thanks!

Tv does not come on instantly when powered up

on these models either lamp or lamp driver(ballast)is defective or both,would suggest to change both at same time..however cost may be prohibitive.
