DLPTV's...INSIDE cleaning??

chefcancook · 08-10-2007, 10:38 AM

I need information on cleaning the INSIDE of my DLP TV. I had a warranty and had it cleaned before but it ran out. I remember watching him do it but I should have payed closer attention. I remember him using a drill bit to take out the screws and remove the entire screen...to which he applied that spray which is safe for HDTV screens(which I already have).....along with the special cloth.

The thing with DLP TV's is that there are a series of mirrors in there that collect dust which than shows up on the screen looking larger than it actually is.....really only noticable when the screen is white or has alot of light colrs going on. So those mirrors need cleaning after time...obviously.

I want to compile some info before i start messing around with taking off that screen....although I doubt its terribly difficult. I am not gonna pay someone to come out and do it as they are asking a ridiculous amount to do so.

If this has already been discussed here on the site please link me....I browsed for a bit with no luck. Thanks.

Best advice is to let a professional clean it. After all, you don't want an expensive TV ruined.

But if you are determined to save the money and clean it yourself, I really don't have experience in cleaning a TV, nor have I been here long enough to have come across such a link.

Good luck either way.

Hmm...of course i don't want to ruin it by trying to do it myself the wrong way. All the guy did was remove the screen and wipe down the inside of the TV where all the mirrors collected dust over the year. And its at that point again. I wish there was some kind of diagram that would show me how to do it. They should have some kind of class for this....."taking care of your DLP tv.Its an investment....not a newborn"

What kind of mirror is behind the screen... Is it just the mirror film or is it glass... Be careful with the mirror, some take delicate adjustments to get correct, you dont want to knock it off kilter. Also always test out that cleaning solvent in a corner of the screen and the mirror, you dont want that stuff messing up anything. Make sure the cleaner has some sort of guarantee as well, as in it wont hurt anything, just in case something does go wrong you will have someone to complain to.

I agree 100%...I love the Evil Dead series!

Maybe there are not mirrors but glass....its behind the screen itself. But i think its a few mirrors because thats the way DLP TV's work....the lamp reflects the picture and it bounces around to create that beautiful view

The cleaner i purchased directly from Tweeter(big TV store over here) as it was recommended for DLP screens. It also came with its own lint free terri cloth to wipe down the cleaner with.

Oh well...you are starting to scare me so I think I am going to call up Tweeter and have them come out and clean it. I don't want to go messing stuff up.

thanks

I am sorry.. I meant it was a glass mirror, not plain glass. Also, the mirrors you hear about in the commercials (...its the mirrors) arent refering to the reflecting mirror but rather the mirrors built into the DMD chip, which you couldnt clean if you wanted to, besides there is no real reason to. All the mirror that you see does is reflect the image from that glass ball you would see at the bottom to the screen, which really isnt that hard to clean but you would have to be careful because as Ive said before, that mirror is adjustable and you wouldnt want to knock it out of alignment. By the way what does Tweeter charge for that... It shouldnt be that terribly expensive, we charge around 60 bucks to do it in the customers home, and 30 bucks if they bring it to us.

Darrylhifi · 08-11-2007, 01:45 PM

While I believe you should let a pro do it, I also believe it is worthwhile, Its almost impossible to own a DLP for a couple of years and not have dust collect on the inside, it can get on the mirrors , it can get on the lens , IMO its a worthwhile maintenence.

BANDB · 08-11-2007, 02:36 PM

From owning a couple of CRT RPTVs, I can make a few general statements about dust on the optics, since these devices tend to be dust magnets.
The only places that dust will appear to be in focus are on the face of the image source itself (face of CRT, surface of DLP chip, etc.), or on the back of the actual viewing screen.
You should look at screen credits or similar that are bright white print on a pure black background. If there is any bleeding of the white into the black, you may have dust on optical surfaces.
I have never seen appreciable dust on the actual mirror itself, and all mirrors I have seen were glass. I have seen spider webs, however

On the ISF thread there is information somewhere on removing DLP glareshields as they perform this service.

Droz...its $95 to have the Tweeter guy just for making the trip. Than its $100 to have him take off the screen and wipe down the dust inside. And the lady added if there was anything wrong with my TV(which there is not)....than it could cost up to $400. This is why i want to take matters into my own hand.

BandB....there is definitely no bleeding of white into black. The dust is not horrible but I notice it during periods of white lights or lighter colors on the screen. I guess i am just picky and want it cleaned though I am thinking of just holding out now. TY for the info.

Irodptl.....what/where are the ISF threads??

thanks guys

Thanks....I wish I had the patience to sift through all those threads to find the info I want but I don't. And most of them are about caliberation....yikes!

Your best bet is to get a service manual for your set. It will tell you how to get your set apart.

www.partstore.com has service manuals for most TVs, so I would start there.

If there is no luck there try google and search for your set's brand and model number followed by "service manual" (yes in quotes) and you should find a site that sells service manuals.
