Question about Projection Televisions
Randomly turns itself off, with self diagnostic light flashing 6 times. Won't restart most times but will sometimes after turning power source off for 10 minutes or more. Repairmen have been out twice (11 months ago and 1 month ago) and replaced a thermal switch (?) but tv is still turning itself off with same number of flashes. I'm not confident they know what they are doing, your advice would be appreciated.

6 blinks is an indication of a missing voltage. It's not the lamp or balast. It may be an indication of a thermal or heat trouble. These sets have thermal protection because of the heat created by the lamp. The thermal fuse may have opened. If this has happened you should have professional check it out. This set has 3 or 4 fans. These should be checked out or replaced. I suggest a Sony authorized repair. This is not a repair I would recomend for you to attempt. This set keeps a record of it's falures and the pro can check for any other trouble also.

From what I've been able to find, the problem is the fan that cools the bulb is not starting when you turn the tv on. Blow on it to get it going or clean with compressed air. The fan could be clogged up with lint etc. It's on the rear left of the tv.
