Hi,
If lamp has not been replaced in tv in last 2-3 years, then replace the lamp as symptom shows that lamp has reached to end of its working life span and causing that problem.
Lamp is not dead or broke but weak so you get above said problem in tv.
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.

TV Wont PWR UP


I had recently had a problem with the Video block or Light Engine as some call it. The TV had blue blotches and streaks in the lower right side of the screen. I sent the light Engine in to TSM INC. in Evansville, IN and they rebuilt it for $300.00. I just got it back yesterday and when I reassembled it I forgot to plug in a connector thus the failure code of 4 red light flashes. I took it back apart and discovered my mistake, corrected it, reassembled it and the TV works perfectly. If you need any help with this process, let me know.

Sony Grand Wega 55" LCD ml # KDF-55WF655 goes protective shutdown


This is the lamp going bad. For some reason, it doesn't spit out that lamp error, it just keeps refiring the lamp and it just cycles forever. When the lamp totally fails, you will get the lamp led lit. Replace the lamp to resolve.

No Picture - Lamp Indicator Blinking


This may be the main power supply, or the lamp supply. This is providing that the new lamp is okay.

The service tech will swap out the modules to service the set.
