If the cooling fan vent has a removable panel then you should be able to access the fan through it. A silicone based type grease should be used directly on the fan shaft after cleaning...do not use a liquid or spray lubricant. The fan could easily displace the oil inside the TV chassis onto parts of the optics engine and do some damage or otherwise affect the picture quality.

Why does my tv not turn on after replacing bulb?


Sounds like the "lamp door switch" is not making contact. Make SURE the lamp door is secure, and nothing is getting in the way of the little "pin' on it--this trips the switch when the door is closed.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

It overheats and pops the Xl-2100u lamp?


by pops? do you mean it explode? how many lamps? it could be the fan that supposed to be ventilating the lamp or it could be the the ballast, why the ballast because the ballast regulates the voltage in order the keep the lamp on, for ignition it sends around 15,000 volts after that it regulates the votage to a small amount of voltage around 5,000 so it could be sending the big amount of voltage all the time never regulates that or it could be regulating and then sending another big amount of voltage over and over until the lamp doesnt handle those changes.

AFTER A FEW MINUTES OF OPERATION ON MY SONY KF-42WE610TH LCD PROJECTION TV THE SCREEN GOES BLACK.THE SOUND COTINUES AS NORMAL.AFTER A COUPLE MINUTES IT COMES BACK ON THEN REPEATS UNTIL THE SET HAS RUN FOR...


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.

FAINT PURPLE/RED PATCHES APPEAR ON SCREEN


http://esupport.sony.com/US/perl/news-item.pl?news_id=206
thought I would let you all know of the recall.

For models:
Models: KF-42WE610, KF-50WE610, KF-60WE610, KDF-70XBR950, KDF-60XBR950, KDF-42WE655, KDF-50WE655, KDF-55WF655, KDF-60WF655, KDF-55XS955, KDF-60XS955, KF-42WE620, and KF-50WE620.



/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.
