Do I need to change the thermal fuse on my sony WF-60WE610 if it blinks red 6 times but it starts after a few trys

That is a Thermal Fuse. IT is behind the area where the lamp is. How to change the thermal fuse on sony kdf e60a20

This video is for a different model but its the same idea as yours.

Sounds like you need to replace your thermal fuse. If this does not fix, then your optics has a problem and the optical block will need to be replaced

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.

have you set the sleep timmer?

3 times means Lamp and 6 means you have lost a voltage. You may have a thermal fuse blown.
This set has a common trouble with overheating caused by the drum fan located on top of the lamp housing clogged up with dust. When the lamp is getting old it runs hotter and that combined with the fan being clogged the thermal fuse blows. You must replace the lamp and thermal fuse. You must also clean out or replace the lamp fan. This drum type fan should be cleaned out every year or two depending on the environment.

Hey there,
I've had my Sony KF-50WE610 for approx. 4years now and have just experienced the prob you described (though I didn't think to count the number of red blinks). I called Sony TV technical support (888-772-7669, #3 for TV/digital cameras, #1 for TV, then #1 again I think). They said that if the power/standby light blinks 5x, that means there's something wrong with the lamp driver and service will be required. Needless to say, I better go home and count my red blinks! Good luck, I hope this helps a bit. Have a happy and safe holiday!

6 blink error is either a power supply (g2 board) or a blown thermal fuse. if it came back on, its not the thermal fuse so you would need a new g2 board. if it blinks 5 times, you need a new ballast (lamp driver)

Jeff, did you look at the Sony web site? They had a problem with 9 different TV models that were from 2003 and 2004, KF-42WE610, KF-50WE610, KF-60WE610 and 6 other models.
This is what it states: It haas come to our attention that a limited number of Grand WEGA rear projection TV's may exhibit warping to the lamp access door. In rare cases, some additional components may also become damaged as a result. and so on........
You probably have some components melted on the inside around the lamp. I have a 42 inch and I just replaced the lamp at Christmas and the door was melted shut. This is the second lamp that I have replaced, the door was starting to melt the first time. They never sent me anything about this problem, and as of today I am still trying to work something out with them. The repair shop who has it told me that it can't be repaired. The parts that are melted are not in stock and they don't make them anymore. They are supposed to get back with me and make me some kind of offer.
They will only fix this problem through March 31, 2009.

You likely have an open thermal fuse. There is a whole procedure for replacing the thermal fuse and some adjustments that should be done when you replace it. If you feel like you are reasoonably technical and can handle the job, I'll try and walk you through it. If not, your best bet is to find a qualified Sony tech in your area. If you contact Sony at 800-222-SONY and they can recommend one in your area

Sorry, I have to say it. If the bulb (LED) is shot it would have to be zero flashes :-) It's my weird sense of humour. After that I hope you'll forgive me and someone can give you some real help.
