Try to Reseat the Lamp....

by Samsung_HD_Tech Samsung staff Dec 22, 2008 5:52AM PST

ChristianAverill,

From what it sounds like, one of two things happened.

1. The bulb may have been knocked loose a little during the move. Not to worry, as if that's the case, a simple "reseat" of the bulb may be all it takes.

2. The only thing that suggests that it might be a bulb replacement is that you actually watched the degredation of the light in the period of a day. That may end up being a replacement. If that's the case, I can help you there too.

In MOST cases, reseating the lamp is just that... opening it up, pulling out the lamp, pushing it back in, and then closing up the housing. Let's try that first before ordering a new lamp.

Here's a Samsung_HD_Tech quick fix, and I'll walk you through a process that will "Re-seat your lamp". If you locate and open up the lamp housing, you'll see your lamp.

Here's an example of what you'll see:

Now, if you either unscrew the two screws where the yellow arrows are, or the one screw where the red arrow is (Depending on the model you have), you'll be able to pull the lamp out a little. Don't worry, the screws shouldn't fall in the unit, as they should be attached to the lamp housing.

You don't have to pull the lamp all the way out (if you do, that's okay), but if you pull it out a little (6 inches or so), and then firmly push it back into place and rescrew it in, and close up your outer panel, that may very well fix your problem.

The outside panel does need to be back in for the television to turn on. There is a blue kill switch there, but you don't want to fool with that.

A few general rules here.
1. If you do pull the lamp all the way out, do not touch the glass face.
2. Perform this procedure while the lamp is cool, and preferably not after consecutively watching "24", Seasons 1-7
3. If the first one doesn't take, try re-seating it again. It may take a few times to reset whatever is triggering the warning.

So a recap: Unscrew the lamp, pull it out a little, firmly push it back in, rescrew the lamp, and close it up and see what happens. It sounds crazy, but if it fixes your problem without a service tech OR a new lamp, that'd be a good thing.

Keep me posted.

Thanks for the info, I'll try tonight after work and let you know how it goes.

I also came across this in the event I do need to replace the lamp: http://www.youtube.com/watch?v=POvahoHUzU4

Accurate? I'd suggest that it is worth considering a series of video tutorials. Very helpful.

And yes, I have often been to CES for PR reasons, many related to Samsung. Do we know each other?

ChristianAverill,

The instructions in the youtube video you posted make the process far more complicated than they should be. We ship our lamps in the housing, so it should essentially be as easy as sliding out the old one, and sliding in the new one. That's how our service center ships them, so swapping out the lamp doesn't require undoing the housing at all.

Now there might be some lamps that ship that way (without the housing) at a discount that I'm not aware of, and that's certainly an avenue I wouldn't discourage, but if that's the way you do it, those instructions seem like they'd do the job.

The latex gloves are essential for that, and I would imagine those lamps ship with a plastic protective coating that should be removed.

Keep me posted!

How to remove the panel?

by ChristianAverill Dec 23, 2008 5:15AM PST

I didn't get very far because did not want to force the lamp bay open, but can you walk me through the best way to access the lamp? I found one screw on the exterior, am I missing others?

Access the lamp

by Samsung_HD_Tech Samsung staff Dec 23, 2008 7:32AM PST

Christian,

There should be a lamp housing that looks like a square box either on the side (usually) or the back (some models) of the television. Most units have them on the side, and there are philips screws holding it shut. It will often look like an access compartment.

Here's a sideways view of a different type of housing:

Using that picture, there is either one screw (red) or two screws (yellow) that fasten the lamp housing to the inside of your DLP TV. Once you unscrew the screws, you should be able to pull the lamp straight out.

Keep me posted!

And to be clear, Should there be one screw on the exterior? I removed one screw and the covering was pretty tough to budge...

One.....

by Samsung_HD_Tech Samsung staff Dec 23, 2008 7:42AM PST

Depending on the housing situation, there could be one, two or four screws to get to the housing. Gently rock the cover after the screw is removed, and it should move enough to pull out.

If you'd like to take a picture of the housing to confirm, send a photobucket or imageshack link, and I can take a look.

Follow up

ok, so tried reseating a few times, no luck. pulled out the lamp, the bulb was busted. replaced the whole thing. everything seems to be working, except the "24" marathon.

would you say the bulb was likely broken due to the move (the TV traveled from NYC to SF)?

Lamp

by Samsung_HD_Tech Samsung staff Dec 26, 2008 12:49PM PST

My best bet would be a combination of both age and movement. The interior of the lamp is pretty sturdy, all things considered, for what it really is. However, like everything else, it has its weakest points.

Assuming the television itself didn't suffer damage, my best esitmate would be that it was a cause of vibration over 3000 miles that weakened the internals. It's a logical conclusion, and by no means conclusive, but might give you some idea of what happened.

If you have any other questions, please feel free to let me know.
