Question about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

1 Answer

I have a Sony KDF-50WE655. There is what looks like a big yellow oval in the center surrounded by blue over the picture. I've read that this is due to the optic block. Is there any other possible fixes for this problem?

That is the sound of a damaged blue LCD unit. Probable cause = overheated due to blocked air ways or an old lamp producing more heat than light.
A very expensive repair. Sorry.

Big yellow spot in middle of screen of sony model kdf-50we655


Most probably it is an issue with the optical block of the TV. Sony aware of the issue and giving free service for few models. It would be good if you contact Sony directly to check for the available options to get the free service. If you wish to know the contact information and timings, please message me www.fixya.com/users/shajanrs

With all due respect, you're asking the wrong people. Only Sony can tell you if you're too late but my experience has been that they're normally pretty fair with considering out of warranty goodwill repairs.
Ask Sony and if they can't help then come back and ask about your problem on FixYa.

thats a common symptom for that model which is usually related to the optical block. Very exspensive repair. Check with a sony authorized repair center as Sony has recognized the problem and offer assistance with certain models yours may be one of the ones affected.
