3 blink error = lamp door.
if the lamp door melts and deforms, you have a clogged fan that cools the lamp. then the door won't hit the lamp door switch. the right way to fix is to replace the lamp door and the fan, but you could clean out the fan and just hard wire the lamp door switch to think its closed to fix the problem. just remember that the switch is there so you can't open the door while the lamp is on and burn your eyes with the UV. you can put a jumper wire in the connector that hooks to the wire to the lamp door switch to bypass. cleaning the fan is easy as long as no smoke or grease is mixed with the dust. remove power to the set, remove the back and front as well as the lamp door. take compressed air and spin the fan up to blow the dust out the fan, it will blow straight out the lamp door hopefully. when you look into the back of the tv, the fan will be just above where the lamp is, on top of the engine. it is a non-typical scrirocco type fan.

3 blinks is a lamp cover error, did you make sure that the lamp cover is screwed in tight? Also check the lamp cover for deformity, there is a problem with your model where the set over heats and melts the lamp cover a little causing it not to make connection with the lamp cover switch. Let me know if you find either of these problems? If not we can troubleshoot a little further.

Kdf-50a11e blink 3 time on red no images no sond when i start it the green lead blink many time then the red led blink 3 time and puse then 3 time


Three flashes indicates either the lamp is not seated correctly or the lamp door is not on properly. I bet its the later of the 2 as THE most common issue is the lamp door has warped because of excess heat building up in the lamp cage. If this is the case follow the link I am providing as you are in luck as Sony is paying for those repairs. Please take a moment to rate my answer...Thanks

Problem for Sony Grand WEGA KDF-55WF655. Hello,


5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?
Thanks.
