Question about Sony KDS-R60XBR1 60" Projection HDTV
After Talking to a Sony Tech, I have learned that the three blinking lights is a problem with the contact for the lamp door. The four blinking lights is a problem with one of four fans which is usually the lamp fan that everyone has to spray with compressed air. Sony with not cover any of these problems under the extended warranty for the optical block problem. So I guess we will have to keep spraying with air, but sooner or later the fan will stop completely and that will cost about 4 to 5 hundred dollars to have fixed.

I had the greenish tint problem and the service technician came out and replced the optical box for free under the sony extended warrantee. The technician exlained that the optical box design gets too hot and destroys teh first LCD screen nearest the bulb (green). The new optical blocks have a filter lense placed in front of the green LCD screen to try to cut back some of the heat so it doesn't happen again. After he left, we started getting the intermittent porblem of the set shuttng down after 2 seconds of picture and the red light flashies four times. For a few weeks, it would eventally come back on if tried a few more times, but last week it just wouldn't comeon anymore. I called the technician and he said that the sets that had the optical box problem, oftern had this problem because the excess heat warped the door on the light. there is a little plastic pin on the door near the screw that goes into a whole in the set and triggers a micro switch, which is intended to make sure the light doesn't comeon if the door is not completely closed. When the door warps just a ittle, the pin does not engage the micro-switch enough and the set thinks the door is not installed. I opened the door and closed it again, making sure it was firmly seated and teh screw was tight. the set started right up like normal. He said he has ordered a new door and will drop by and put it on when it comes in.....also complete;ly covered by the Sony extended warrantee for teh optical box problem. Hope this helps. The set has a better picture than any other projection TV I have seen....when it works. I am still glad I bought a Sony because they have stepped up and taken responsibility for this obvious design flaw on a $4K TV. What amazed me is all the postings I read where people have no idea why this is happening. My technicain said he changes a couple of optical blocks a week and knew immediately that the warped door was the four red light problem. He has changed so many, that he said his first time it took almost 3 hours ( all the guts of the set have to come out to get the optical box out...not something i would recommend for the amateur), but now he does it in 45 minutes.....which I witnessed. He also took the time to vacuum out allthe inside of the set when he had it all apart. Loquatius
