Sony cuts off - red standby flashes three times

Posted by on

  • lancealanta Feb 10, 2009

    Same exact thing. I turn it on the stand by light blinks green the TV flashes on for split second then goes off and standby light blinkd red three times. Just replaced the bulb about a week ago and TV worked fine except it know had a green glow to the picture. Service tech came out to replace the optical lamp and couldn't get the tv to turn back on again. He asumed bad optical fan so he replaced our old one back since it was working when he got here but then the same thing happened, he re-replaced the new part and again same thing so he put our old part back in and still same thing. Now he claims we broke a switch where the bulb went, after he had to remove it 4 times, ya right! Can someone help, Please?

Sony grand wega kdf 60wf655 will not start up. red light blinks three times. lamp replaced a year ago.


If the POWER/STANDBY indicator flashes three times, the lamp cover may not be attached securely. Review the lamp-changing instructions in your owner's manual, and make sure that the lamp cover is securely attached.

Sony kdsr50xrb standby light red 3 times


If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.

NOTE: You may have to replace the lamp also if the issue persists.

Here's an excerpt from the Sony Manual online. And the link - http://esupport.sony.com/US/perl/webtree.pl?template=EN&mdl=KDF55XS955&content_id=68&category_id=11&problem_id=52

The POWER/STANDBY (red) indicator flashes three times
If your power/standby indicator is flashing in a pattern of three flashes, this may indicates that the lamp cover is not attached securely. Follow the directions in the Operating Manual under changing your lamp that related to closing and securing the Lamp Cover. Ensure that the Lamp Cover Door is securely fastened by tightening each screw.

The POWER/STANDBY (red) indicator flashes continously
If your power/standby indicator is flashing continuously, and the lamp cover has been secured, your TV may be in need of service.

The POWER/STANDBY indicator is lit up green (not flashing)
A sustained green light indicates your TV is on.

The POWER/STANDBY indicator is lit up red (not flashing)
A sustained red light from your power/standby indicator simply indicates that your TV is in standby mode. This shows you that your TV is ready to be turned on with the remote.

Is it the power light and not the lamp light? If the lamp light is flashing then replace the lamp.

Standby Red Light Flashing


six flashes corresponds to "Horizontal deflection stop". In turn the "supposed malfunction" is then either Q5013 (H OUT) is broken and/or IC507 (H Jungle) is broken.
however i would check
Video out, IC7101, 7201, 7301 and others in C board circuit.
Q510, 516, 524 (A board).

There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.
