Question about Sony Grand WEGA KDF-55XS955 55" Rear Projection HDTV
According to the manual (you can see it here) page 122 that describes 3 red flashing lights:
"The lamp cover is not attached securely. When you secure the lamp cover, the POWER / STANDBY light flashes in red and the LCD projection TV enters the standby mode (see page22)"
Page 22 says:
"... if the POWER / STANDBY light flashes continuously, this may indicate the display unit needs servicing..."
Most DLP displays make use of a "color wheel". These small motors spin at many thousands of RPM. They often begin to make scratching sounds when they are beginning to fail. Some manufacturers make it difficult to change yourself - and others make it pretty easy.
I hope this was at least a good starting point for you & good luck. Please rate my reply. Thank you.

Tips for a great answer:
If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.
If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.
If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.
When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.
If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.
