Sony KF-50WE610 flahing red light (6 blinks)

The TV shuts off and the standby light blinks 6 times. I can unplug it for a few minutes and it will work for a short time once plugged back in.
Just replaced the thermal fuse (by a service tech guy -$149). Same problem happened as soon as he left.
Any ideas?

    I have the same problem Jeff. Did you find a solution?

    Hey, thanks for the tip... we had just about given up on doing anything with this TV and were about to go buy a new one- not something we wanted to do. I'll check out the Sony site and go from there. My repair shop had no clue and then told me $500 would motivate them to find an answer. Needless to say I took the set back.

    I'll let you know what happens.

    Thanks again!

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.

First blush - the protective device called a "thermister" is heating up and "fusing". When the system cools down, the thermister releases the protection and allows the highvoltage transformer to provide power again.

Often times a device is drawing too much current - and the thermister shuts off the device to protect it - much like a fuse.

I have been able to maintain service on my TV by adding more cooling air to the existing fan. If your cooling fan is not turning fast enough - it can also cause the problem.

Sony kf-60we610 stand by blinks 5 times


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!

Won't piwer on


Tried to turn it on? Sounds like you need to replace the lamp. However, I got an additional week out of my unit. Although poorly dimmed and the red Lamp light blinked constantly for that one week, at least it gave me enough warning to seek out a replacement. But so long as you're not mistaking the Power/Standby or Timer light for the Lamp light then I would have to agree with you. http://store.l-f-l.com/prod/A-1606-034-B Includes shipping to the United States and no sales tax outside of California.

4 blinks = No Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505.
