Question about Sony KDS-R50XBR1 50" HDTV
Okay I got the dreaded red blinking light 4 times on my 50" Sony SXRD. I called Sony and they said it's a fan not working correctly. I took the back cover off and when I power up both fans kick in for about 5 seconds until the green blinking light in front turns to the red blinking light.
My question is, does this sound that like a fan problem since both of them kick off at the same time after getting the red light special? Fans are not dusty at all.
Also I heard there are 2 more fans somewhere in the TV. I can't locate them. Does anybody know these fans are located?
Any advice would be greatly appreciated.
There are 2 more fans, 1 is in the middle of the base housing, 2 screws, should be clean. the other is on the left behind the circuit board in a black housing. This fan when i removed it was CAKED with dust and there is no way it could have had any effect on air circulation. the fan is inclosed and you have to take out the whole circuit board to get to it.

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.
