Can I use an optical block from a KF60WE610 in my KDF60WF655 tv?

Optic Block failure. Lamp wont help you there unfortunately. The KDF60WF655 was a good TV back in its day. Don't waste your money on repair and return the lamp if you can.

Sounds like you need to replace your thermal fuse. If this does not fix, then your optics has a problem and the optical block will need to be replaced

Optical block needs repair

Your optical block is going bad. Sony has made a recall and is offering to pay around 70% of a new tv. Call this # 1-800-282-2848 Hope this helps.

Tries websites like Partstore.com,Tvrepairwold.com,Ebay.com.The all sell optical projection engines.

optical block about 900 unless you can get a good used one. thats a common problem with that model

You have a bad optics block. This issue can be caused by poor designs within the cooling fan for the optics block. Check your lamp door for warping and if it is present check the surrounding area as the fix maybe covered by Sony. Go to the following website if you do see the warping for directions on what to do..

I had the same problem with my 4 yr old Sony KDF60WF655 rear projection set, and I was fortunate to buy a 4 year extended warranty - because it was the "Optic Block", ($1300. -not incl labor), that was replaced to fix the problem. That part contains all new LCDs, & multiple Lens & some electronics. I had already got a new bulb (under warranty) a few weeks earlier, that I had not yet installed so the service guy did replace that as well. (This happened 3 weeks before my warranty ended).

He told me that he replaces hundreds of Sony Optic Blocks every year and that many Sony Rear Projection sets have automatic FACTORY extended warranties (up to 10 years), because of some known problems with the blue LCD panels. You might want to contact a SONY office & see if your set is covered.

ALSO - The tech checked my Service Codes & showed me the TV had been running for 10051 hours in about 4 years - on the Original bulb! He was quite surprised because he said the bulbs usually last about 5000 - 7000 hours. He also said it's good to replace them BEFORE they go bad, because they can sometimes burn out the amplifier that powers the bulb, (which is a seperate piece that attaches to the outside of the Optic Block). My TV is like new now.

You will most likely need the service manual to pinpoint the problem correctly. If you do not have a manual you can ge one at the following link. I believe its 10.99. They will also email you after purchase to inquire if you would like the manual emailed out right away. I have used them many times and I always get my manuals emailed to me very quickly. Here is the Link.
