Not really if the set is turned completely off there will be no light at all, normally a yellow or red light on a tv is not a good sign .

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!

Re Degaussing


Now Degaussing and convergence are two different things, if you say its degaussing then you should have just a color differential in a certain area, meaning the color should not be arched, everything that passes through should pass throu only with the changing of color. Now if its a convergence the the color may lift upward in an arch, likely separated from the other colors, Red, Blue,or Green. So now which do you think you have? Deguassing usually give you a highish green color or yellow
