Usually a flashing power light on a rear projection TV means a bad bulb, try replacing the bulb. Also try unplugging it for 10-15 minutes, then come back and plug it in and try again. Also if its been a long time since its been serviced it could be dust buildup causing overheating, do you hear the cooling fan running? It could also be a failed cooling fan. Generally the first thing i do with projection TV's is clean them, clean all the vents, pull the bulb out, clean out the cooling fan and bulb housing, and then try a new bulb. If that doesn't fix it then its a bigger internal problem and there is no quick fix but have it serviced.

bad lamp, thermal fuse will power up tv. Blue haze is optical block.

Sounds like it just needs a new lamp.
The way to tell is the lights in front:
green blinking as TV reboots = bad lamp
red three blinks = door switch
red four blinks = bad fan
6 or 9 blinks = bad thermal fuse

Hello.
My name is Russ. Maybe I could help you, but I need to know model number of your TV (it is located on the sticker at the back of your TV next to serial number of the unit). Also I need to knoe exactly how many times red light is blinking. It does it repeatedly. Foe example: six blinks, pause, another six blinks and so on.
Regards.

Try to access the self-diagnosis screen. With the TV off, push in sucession, the "mute, then the number "5" button, and then the volume down button, and finally the pwer button. When the picture comes on, there will be a list of different circuits and to the right are numbers which represent how many times that particular circuit had a malfunction. Sometimes the red blinking LED code is itself in error, so this may help to clarify the root cause of your problem. Now, if the TV will not stay on long enough to perform the previous operation, you should consider replacing the large exhaust fan that is in front of the lamp assy. This has been the problem fan in these sets.

Yes this can be cause by over heating so better check the fan if they are working fine..

Hope that helps........

sounds like the unit is truly unhappy, eh? the power board is most likely down de tubes, mon

I get 5 blinking red lights for about a minute or so before it powers back down. The Sony TV has a specific light that i presume is supposed to light up when the bulb is out. I'm unsure if this is what it is.
no picture, no sound. tries to boot with green light blinking a few times. then goes to red blinking light, six in all, then waits a few moments, then another 6 blinking red light.
Bulb was already replaced several months ago but we do have the TV on for long periods of time.
