Question about Sony Grand WEGA KDF-55WF655 36" Rear Projection HDTV

3 Answers

Standby light blinks 6 times

I have a Sony KDF55WF655 LCD projection and the unit will not turn on. The standby light flashes green and then to red with 6 blinks when trying to turn unit on. The redlight will continue to cycle red with the six blinks. Arox. one year ago this same thing happened and the repairman replaced a fuse. I have searched the large panel borads in the rear back corner of the unit and the only fuse I see is a glass fuse. If I remember right the item the repairman replaced was a wired fuse. Is this correct? Where do I need to look? New bulb does nothing as I have a spare.Thanks

    After playing, set will turn off with the green light blinking maybe nine or ten times and then come back on. It may happen again soon or may play for some time before it happening gain.

    I also have the same issue with the KDF-55WF655 55 inch. After turning on the tv will automatically turn itself off after a min or so. The power light flashes approximately 30 times and then the tv turns itself back on. It then stays on for a few minutes and then the continuous process of automatic shutting off and on repeats itself. Any suggestions? The Sony manual offers no suggestions and the Sony technical support online is "offline"!

The thermal fuse is p/n# 1-910-023-93 come with fuse + cable + connectora and is 102c 1a 250v rated. It's a bit difficult to install without removing the light engine because it sits on top. But I have slid the housing assembly back far enough to do it without.
If you want a real good idea what you're looking for order the part, you can't miss it then...

If i turn on tv i here clicks and red light starts to flash 6 times in a row and just keeps flashing can i fix this my self ?

Hi, there are numerous flashing codes for these sets so I included a web page dedicated to the Sony flashing light and you can look the forum over and try and pinpoint the number of flashes and the related causes. I also included the cuase for the 6 blinks and this can be fixed if this is the only issue.
Usually, the problem resulting in 6 blinks, pause, 6 blinks, etc. is a defective thermal "fuse", which is actually a bimetalic temperature switch. You may find the "KDF55WF655 6 blinks/KDF42WE655, KDF50WE655, KDF55WF655, KDF55XS955, KDF60WF655, KDF60XS955" information package of value. See the "Frequently Asked Question for Sony Products" forum "Television Troubleshooting Infromation Packages" thread for more information.
Once you get to this site request the troubleshooting package. It has step by step on how to replace the thermal fuse and where to get the parts.
I believe this fuse is right next to the light housing If you find this helpful a vote on the thumbs up would be greatly appreciated for this free advice and thanks for using Fix Ya

No pic or sound. the stand by light blinks green then the lamp light blinks red untill it turns off all toghther. the lamp is broken i just want to know if that is the only problem or if the driver may...


Flashing green standby led light at the front panel is an indication that the unit waiting for the lamp to turn on. Since the lamp led light flashes, the unit sensed it already burned out.
Faulty lamp driver has a different error code which is "flashing of the standby light 5 times".
Your unit will back to normal operation again after the lamp replacement.

Hope I helped you.
Have a nice day!

Sony LCD Model KF-60WE610 lamp was replaced and then it shortly after stopped turning on. Blinks Green 6 times then Red 6 times Please help!

For Sony Model KF-60WE610, KF-50WE610, and KF-42WE610, the Diagnostic Code of power light indicator flashing 6 times green, then flashing 6 times red (6 red etc), means you need to replace part number A-1302-272A G1 BOARD, COMPLETE. See Sony Service Manual, 4. Chasis-1 at part Ref no. 103. The Power Board sits vertically in two slots on the left side of the electronics board. 4 wire connectors to remove when replacing. This component fits all 3 KF models listed above.

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.

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 -

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.
