Question about Sony Grand WEGA KDF-60XBR950 60" Rear Projection HDTV

1 Answer

I have owned a Sony Grand Wega for about 3 years now and for the past few months the TV has been making a very loud noise. I thought the noise was the fan but came to find out it was not the fan and was coming from the bulb area. I have no idea what the noise is and it is very loud.

    Thanks for the help, I just tried and it seems as though the noise starts before the lamp turns on.  


    (I can also hear the low pitched "whirr" noise once the lamp turns on but this isn't not loud at all)


    So I was wondering if there are any good sites that will show how to change the fan or get to the fan.  I have taken the back panel and front panel off but couldn't really find a way to get to any of the fans in the front.


    Thanks again for the help.

Hello,

There is a fan beside the lamp chamber in this TV. There should be 4 fans total, and the one beside the lamp chamber might be making some noise. They are all bearingless fans, so the noise should be relatively low-pitched "whirr" if it is the fan. If the noise is more of a buzzing sound, it could be coming from the lamp driver (ballast) or from the lamp itself. Lamps tend to do strange things toward the end of their life.

If you have never changed the lamp, it is about time. They have a 2.5 -3 year life span with average use.

One thing you can try is to turn the TV on from a cold start, and watch inside the vent areas beside the lamp chamber. If you hear the noise before you see the lamp light up, then it is probably a fan. If it starts as soon as you see the lamp light up, it is the lamp or ballast.

Hope this helps you...

Loud Fan Noise


This is a free repair on the optical block/engine. For specifically a road mapping issue. (Where there is sparactic grouped lines on the screen of the TV)

Otherwise there is a full recall on all 50XBR1's and 60XBR1's for ANY video issue.
But the bullentin I do have on that is Confidential due to the amount of claims SONY could recieve. But here is a sample of the bulletin.

Models: KDSR50XBR1, KDSR60XBR1

Subject: Optical Block: Warranty Policy and Part matrix by serial number.

Resolution: As part of Sony’s commitment to quality, Sony is announcing that it is extending the limited warranty (parts and labor) for optical block replacements on the models listed above until October 31, 2008, regardless of purchase date. Authorized servicers should follow the normal process for warranty claims for this issue.

Excessive Fan Noise


If I may - - the Grand Wega has a common color wheel problem and it may not be the fan at all... If while you are powered up listen carefully to the noise as you hit the power button - does the noise go away or is it still there? If rough noise stops and you can still here something in there running at a whisper then your problem is a bad color wheel not a fan... If it doesn't stop and it is the fan you'll most likely need to replace it.. Like Lemmor said you may need to clean your air intakes, which you can do with the hose on your vacuum but that is a brushless fan and no oil change in the world will help it..
