Light Engine Replacement

rwdomkr · 11-15-2008, 01:32 PM

Hello all - newbie here.

The light engine on my Sony KF42WE610 has gone out. I'm mechanically savy, so I'm not afraid to jump into it ... does anybody know where I can find the step by step procedure to remove and replace the unit??

Many thanks!!

Welcome to the forum.

First, I checked Sony's recalls and your set does not appear to be one of the many RP sets for which they have extended the warranty and are doing free Optical Block replacements.

The info you're looking for is sometimes contained in the set's Service Manual. Try an internet search for something like: "Sony KF42WE610 Service Manual" and you will find internet vendors selling manuals. It would be nice though if you could make sure light engine replacement instructions were included in the manual before purchase. Perhaps someone else here can tell you for sure or has better info.

Replacement light engines are also available on line at better prices. Again, perhaps someone more knowledgeable here can tell you who is reliable and is selling quality parts.

More thoughts: brand new 42" lcd and plasma flat panel HDTV's have dropped dramatically in price and are headed down even lower as we approach the holidays. The technology contained in these new sets is, in my opinion, significantly better than the now-defunct Sony RP tech.

If it were me, I would not invest several hundred $$$ in repairing an "older" RP set like yours. By the way, repeat light engine failures are far from uncommon after replacement.

Yes, I know it's difficult to think about replacing an expensive TV that is only 5 or so years old. Unfortunately, that is reality in today's HDTV world. High quality flat panel sets made by first tier manufacturers should do better going forward. Time will tell.

Good luck.

BuTal - thank you for the good advice. Yes, you're right. This is the second light engine to fail in this unit. The original lasted two years, the second three. I have found a replacement unit on-line for around $300.00 and since I've already gone to the trouble of disassembling the thing I think I'll go ahead and replace the engine one last time.

Many thanks!!

Just can't resist tempting you one more time

Not a top of the line set, but exceptional value for the money. We'll probably see it for even less at times during the holidays. Plenty of lcd flat panels at similar prices out there too.

Good luck with the repair. Hope it goes smoothly. If you suffer another failure, at least new set prices and technology may be even better at that time.

I have the same model television.

Sony KF42WE610

I've had problems with this television for 2 years. First, the optical block got dust on it, creating spots all over the screen. Then, a month after an extended warranty (for the optical block) expired,(June/08) there was a blue haze that started creeping in on the top of the screen. BSOD!

Fortunately, if you choose to look at it this way...

Sony recently issued an extended warranty for a warped lamp access door that extends until April/09. My door was melted, and the inside of the housing was as well. I contacted Sony and they issued an e-ticket. An authorized repair person was here today, and called this afternoon to report that the parts are no longer available to fix this issue. Sony will be contacting me in a few days to negotiate a replacement. I've read at least two other accounts of this problem and how Sony offered very little initially, but caved after the threat of making the experience public by documenting the frustration on various forums. In both cases, a credit of ~$1500 towards a new set was offered. I expect at least the same, having paid $2500 four years ago, and having less than two years of good operation.

Check your lamp access door! You may be eligible for a credit.

Good luck.

It is good that Sony is recognizing these issues, especially since they (and others) have left the rear projection scene.
Once I got it working again, I would sell it and go for a more modern technology.
The Panny referenced is certainly a great option, and selling your Sony will save you another few hundred.
