Lamp Ballast Replacement on SONY RPTV LCD Televisions

I have the KF-60WE610. Bought in Dec 2003. Replaced the first lamp burn out on Aug 2007. Has burned out again in only 1 year, probably about 1,000 hours. Replacement lamp does not have either OSRAM or Philips markings, but is Made in Japan. Lamp was replaced by circuit city under warranty.

Given that the tv set is 5 years old and a lamp has burned out so quickly, would it make sense to go ahead and replace the lamp ballast (driver) as a preventive measure? I'm guessing these are subjected to a harsh operating environment, degraded, and may have played a part in the early lamp failure. Do lamp failures decline after ballast replacement? The part is only $106 at the Sony site. The part appears to have an upgraded part number, so it is possible that there have been improvements in its design.

The lamp driver pretty much either works or it doesn't. Examine it to see that it's plug-in connections aren't charred, and do make sure the fans are clean. They often get so occluded with dust that the lamp gets insufficient cooling, shortening lamp life.

Thanks for the reply. Is the why some of the lamp housing doors overheat and warp? There is a SB on this I believe. My lamp area does not exhibit any signs of excessive heat.

Yes, that is why the doors warp. I believe there was also a class-action regarding this, at least pertaining to certain models.

The later version replacement fans are a bit more tolerant of the dust buildup, but they also can clog up due to dirty/dusty locations these sets are subjected to. Seen way to many of these sets that have deformed doors, lamp housings, and other related plastic parts.

Many of the after market lamps only last one month or less. I used them in Mitsubishi, Samsung and Sony TV sets, and was having a nightmare! my company gave up on after market lamps and switched to OEM.

Where did you buy the lamp from?
