Bad Blub? I have a KF-50WE610 Sony and it started to have trouble powering up. It would take a while to power up and I finally figured out that the bulb was going bad. With the old bulb it took a while to power up. Sometimes you could hear a buzz and I assume that was the 5Kv power supply trying to power up the bulb. Now, I have a new bulb and the TV powers up right away. However, 2 or 3 minutes later the screen goes black and stays that way for 1 or 2 minutes. Then, the screen gets bright and all is well for as long as the TV stays on. If we power down for an hour or so, It will do it all again. This can't be good for the bulb. Any ideas? TIA, Joe

Re: Bad Blub?

It could be a bad ballast or a light engine issue.

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.

    Vertical colored lines on Sony KF-50WE610

    Hi Lucian

    This is a common Mainboard failure problem on Projectors.

    The unfortunate thing is that this can only be solved by having the part repaired or replaced.
