Does anyone know how to clean the inside of the LED screen? Mine is full of dust and black spots. Slides have been in dustproof container, so why?

My slide copier came with a plastic bar that has a cleaning pad on the end of it. When the feed tray is out of the copier, this cleaning tool slides in on the top of the LED screen. slide it around to clean the screen. -------Don

There is a tool enclosed with the viewer to clean the screen, worked well with me.

take it to your local garage, drop him a couple of quid and ask him to blow it out with an airline. I will not do any harm, or just use the cleaning stick supplied.

It worked fairly well, i had to clean it several times though..and be careful because it would get caught on the inside.. i would think canned air might work better.

I dis-assemble and clean the screen as it needs it. Regular cleaning will keep it in perfect condition. It is also so cheap to purchase that you are better off trashing any broken units entirely and buy a new one. Be sure to handle the plastic cup carefully by not over tightening, and wet the "o ring" to ensure a water right seal before using and everything should last a very long time. I've had mine for over a year with no problems.

I can only can give my opinion but, in any past experience I have had regarding LED displays like this is not good. Generally, you would have to replace The whole display module.... But I might be wrong. :0/

I think that is true. I noticed the light stays the same, but I haven't bothered to get the manual out to find out if there is a way to reset it. I just clean it periodically and it has been fine. Still works really well and has significantly reduced the dust in my bedroom.

I am having the same issue with one that I installed approx two yrs ago for my Mother. It has worked well until the last two to three months, the screen looks clogged at the moment and I am trying to find out how to remove or unclog the screen. I hate to punch through it as this area is known for having stuff in the lines. Would rather not subject the faucets valves to grit if possible. Feel I have located problem but still have no solution to fix it yet.

Hi Jay, I have to say I'm puzzled as that is not what I experienced when I have scan negatives. You are not scanning slides are you? I have tried that. I'm sorry if I am not much of a help.

I have not cleaned mine. i think the idea is that the wavelength of light emitted destroys particles in the air, not that it has some fan-type air filter attached (sorry if that's not clear or correct-- I'm not a physicist). Just saying that mine appears to be an ordinary lightbulb.

I had the same issue then I read that you need to clean the plate in the unit often. So you need to get like a took brush of something you can clean that little black disc inside with then clean it and then your unit will work again. Thank you

I've had multiiple problems with this model. First I had the "white dot" problem. At first a few white dots show on the screen. Then every day there are more and more until the screen is a star field. The DLP chip had to be replaced to fix this. Then I had the problem you're describing. It wasn't the LED which lasts about 10 years (unlike the non-LED models which have a bulb that needs to be replaced every 3 years). It was either the motherboard or DMD board. I forget which, but I ended up paying $600 to have it fixed. It was out of warranty.

Yes, I once exposed a screen longer than the recommended time and it was extremely difficult to remove the part that should wash out. Instead of coming out with a forceful spray of water I had to scrub. I believe it's important to stick to the exact time listed for the light source you are using.

Im sorry... No suggestions... That sadly is exactly what happened with me. I just threw it away after about a week of it not turning on showing any motion with the lights. Maybe flip the black switch on the bottom and it may work.

I'm at work and don't have the box in front of me, but I believe it's an LCD screen but it's backlit with LED lights. When my last LCD went on the fritz, I discovered that the screen was backlit with fluorescent tubes and one had gone bad. So the new thing is to backlight the screen with LED. Should save energy and the bulbs are more stable.

Rami Elamine and David P. Bard, can you comment on whether you are using a screen protector, such as ZAGG or InvisiShield? I have seen a few complaints like this that appear to be related to the dye in the cover soaking into the screen protector. Or is it actually causing problems on the screen itself?

I would send it back. I have had mine for some time and have had no issues with mine. Sounds like a bad light sensor. Good luck.

My light did the same thing. I unscrewed the head with the LEDs from the body where the batteries are. I was checking for lose or burnt pieces. After I put it back together it started working and has worked fine ever since. I believe the lights worst problem is little to no quality control at the manufacturer.

I don't know exactly what the problem is but the same thing happened to me. I sent mine back to Nebo for replacement/repair which was successful. I suspect the problem is high heat generated from prolonged use causes damage to the LED, which would be a fundamental design flaw with the device. I have since tried to limit continuous on time for this reason.

I converted mine to LED as soon as I got it, I still have an issue with the beam, I haven't been able to adjust the spot out of the D Cell like with the MiniMags either. Sorry I couldn't be of any help
