DO NOT under any circumstances touch the red wire inside the set. This cable connects to the picture tube and carrys 33,000V and can cause injury. The 3 blinks are a diagnostic code that indicate the defective circuit. Please confirm the model number as KV-36FS120 and I'll look up the code.

There is no Lamp door if this is the KV model mentioned above as this is a CRT based set not a projection set.

Please confirm the model number so I can get you a proper solution.

Thanks,
Dan

    There is no lamp door on your model because there is no lamp. Thank for confirming the model number. When I get back to the shop, I will look up the code and update this again.

3 flashing light on a Sony typically indicates an open lamp door on the back of the set. If the door is properly closed it could be the lamp door switch.
If you find this is the case you will need to unplug the set for 1 minute after properly closing it and allow it to reset.

The other potential fault is a faulty IC inverter board.

Red flashing light


  1. Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

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.

Dead sony


The $1200 was for the lcd engine not the lamp. You should change the lamp. The buzz is the power supply trying to light the lamp.

Sony Wega 55" Replaced Bulb TV still does not work


Hello, please check how many times the red light flashes. If it is 3 times this means that the lamp cover is not fastened securely. If the red light flashes 5 times this means that the lamp driver is defect. If you need more help please advice
