Question about Sony Grand WEGA KF50WE610 50" Rear Projection HDTV-Ready Television

1 Answer

I have a Sony KF-50WE610 LCD and I recently replaced the lamp. Now I have 3 blinking red lights and the power turns on and then shuts off. If I push the on/off button several times, the power will eventually come on and I'm able to watch t.v. Is this a power supply problem?

    Error Diagnostic Blinks for the Sony KF-50WE610 is as follows

    3 Blinks -
    Lamp cover is not attached securely
    4 Blinks -
    Fan Stopped
    Temperature Error
    5 Blinks -
    Lamp Driver Error
    6 Blinks -
    B OVP Error
    7 Blinks -
    Audio Error
    8 Blinks -
    D-OVP Error

    Lamp Light Lit
    Lamp is burned out

    This was taken directly from the service manual for the KF-42 KF-50 KF-60 WE610 which i had purchased after Sony refused to tell me what the diagnostic blinking meant. I hope this prevents someone else from giving Sony $20 for what they should tell their customers so they can order the part and resolve the problem

    Check the Sony website for service bulletins on your model. Sony sent out a service technician to look at my unit and determined that it was covered under the bulletin and Sony replaced my tv with a new 46" 1080p LCD. i suppose i may have gotten lucky but its worth a shot. apparently these models have a huge problem with the lamp melting the case and damaging components so take off the front panel and look at the lamp cover, if it shows any signs of melting then most likely it will be covered under the bulletin. mine was doing the same thing with blinking a bunch of greens before going red or the lamp light would flash so check that out. if you want to email me directly i could give you more info or tell you how to open the front cover and what exactly to look for. if you are really die hard about fixing the tv, i removed all the working and good boards from my kf-50we610 and would be willing to part with one you may need. kenmckayjr@comcast.net

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.

Sony LCD KF-50WE610 no picture-red light blinking


3 times standby red light blinking shows that lamp cover has not been placed back properly after lamp replacement.
Make sure lamp cover, (the first thing that you removed to replace lamp in tv) is fixed securely then turn tv On.

Sony KF-50WE610 Tv won't turn on, red light blinks 6 times


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.

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!

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


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.

KF 42WE610 turns on for two seconds, then goes black


no, had the same problem. Its the lamp ballast also called the lamp power block. It supplies power to the lamp, any how some repair shop wanted $450 to fix it, so i ordered the part from sony, part #146879816 ($116.25), trust me this is the part I double checked with many different places. Any how fixed it my self took about 15 minutes, just take the back cover off and the part is right there just kind of follow the screws and the 3 wires, super easy job, I suggest you replace the bulb at the same time, dont by a cheap bulb just get it from sony

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.
