Seems dead took apart cleaned vacuumed still no power to start have power going into PS board at 120v Checking from Gnd across fuse only shows 60v? Normal? or does it sound like something is open in power supply? I like this tv and enjoy the challenge to repair it I can replace power supply pretty cheap if needed or can replace caps or burnt parts if i find any but would sure like professional input as i am not a tech Planning on pulling PS soon not sure if its marked with voltages on board to check? I believe i should be getting at least a standby light but chassis seems dead Thanks for any tips,help or input Dan

1 Answer

I have a 55" sony


According to the manual (you can see it here) page 122 that describes 3 red flashing lights:

"The lamp cover is not attached securely. When you secure the lamp cover, the POWER / STANDBY light flashes in red and the LCD projection TV enters the standby mode (see page22)"

Page 22 says:

"... if the POWER / STANDBY light flashes continuously, this may indicate the display unit needs servicing..."


Most DLP displays make use of a "color wheel". These small motors spin at many thousands of RPM. They often begin to make scratching sounds when they are beginning to fail. Some manufacturers make it difficult to change yourself - and others make it pretty easy.

I hope this was at least a good starting point for you & good luck. Please rate my reply. Thank you.

TV WONT COME ON AND THE LIGHT KEEPS FLASHIN RED AN GREEN ON THE STANDBY BUTTON


  1. If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

  2. If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.

  3. If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.

  4. When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.

  5. If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.

Tv wont power up Standby light keeps flashing.


First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.

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.

I just replaced the lamp on my sony wega 42WE655 tv and the lamp replacement indicator light onthe front no longer indicates that it is bad, but the standby light keeps flashing red. when i try to turn it...


If you just replaced the lamp then there's something wrong in the power circuit or you have a bad lamp. If you can I would take the back cover off and look at the board where the power cord connects and lok around it for swollen capacitors. Let me know if you find anything.

Tv went off while watching a program power standby red light blinks 6 times then pauses then repeats tried unplugging unit waiting a few minutes then replugged same results nothing. can anyone help me ?...


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.
