You have to disassembly the unit. Most of the screws that need to be removed are on the back of the unit around the face's edges. But there are a few inside that need to be taken off, and the front bottom needs to be removed.

Why are my photographs printing darker than on screen

Pictures have come a long way... but satisfaction really has stayed where it's at. The screen as you call it is a series of mirrors or lack of in your see a crisp image and like what you see; push the button and the process of duplicating what you see on that "screen" commences. image lenses mirrors shaping cicuitry fading ,more mirrors, a few lasers a few more mirrors and then finally to the drum/developer/toner section, which is added to or subtracted to depending on about ten human control factors and a few non-human things like the original, paper being used ,age/number of copies om color unit and good ole' dust on imaging surfaces. Other than that it's fairly simple. ( spend 120.00 on a good cleaning or give it to your kids and buy a new one) ~~~~SC

Mitsubishi 62525 static on screen more noticeable with dark background cleaned filter and replace lamp

A few of these (not sure if this model) have two mirrors inside--stupid idea and only a few had that--.

If this is the case here--little mirror (I mean LITTLE) is at bottom pointing up from the optical lens--gets dust and such from the fans= picture gets darker to the point where brightness is very diminished.

Mitsubishi can tell you if it has two mirrors (the large one in rear of set must not be touched and never needs cleaning as any finger prints etc will show in the picture.

If two mirrors I can tell you what to do--15 minute two person job.

Mitsubishi dlp tv picture is getting darker

One of two possible issues:

1. Lamp is nearing end of life and may dim just before total failure.

2. A few of these models have 2 mirrors(check with Mitsubishi to see if yours is one) A large mirror in back (never gives a problem and do not try to clean it. Some idiot in these sets used a small mirror inside that the optical unit shines the picture into (wedge shaped mirror and small) and it is facing up----the fans intake air from the front of the set around this mirror--it gets coated with lots of dust---Picture can loose up to 70% of its brightness and clarity if that mirror is dirty--looks like 20 year old set .

If you do not wish to check with Mitsubishi GOOGLE THE MODEL NUMBER with "mirrors" to see.

If it has 2 mirrors I can tell you exactly how to get at it.

I was wondering if u know y my mitsubishi tv wasnt showing a clear picture i replaced the lamp with new one but it still shows a dark picture

This may be a model that has two mirrors. Mitsubishi could tell you if this is the case.

Some idiot had the bright idea to have optical unit shine picture into tiny mirror which puts it into large mirror in back; problem is tiny mirror if there is at bottom and facing up, dust or dirt get on it and picture brightness will diminish up to 70% or more.

If model you own does have two mirrors, the front of the set with the screens will have to be removed to clean it, not real hard and takes 15 minutes.

If you can confirm it has two mirrors I can tell you step by step how to remove screen unit and resolve problem. Usually if tiny mirror dirty it will happen over time, picture will gradually get darker and dull looking.

Let me know if want instructions, the set either has two mirrors or it does not.

My JVC 56G787 is dark and bright is turned all the way up

You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

Shadow on Flat Screen TV

Projection TV correct? This may take some work but it is common for a spec of dust to settle onto the Mirror inside the TV, The back side of the TV screen or onto the Lens from which the Video image is projected. Some TVs have ports that allow you to access the inside of the TV from the side, others you must remove the screen.

This is not something to do every day or every week and it will not improve the picture. You only do this when you notice that it is dirty. Any more than that and you yourself will create a bigger problem. ONLY LIGHTLY DUST the screen. Soaps, water and windex will leave streaks, damage the screen and cause more trouble.

Projection TVs are the eqivalent of a big flashlight showing onto a wall. Put you hand in front of the light and you get a shadow.

Inside you TV there is a light (the TV picture) that bonces of a mirror attached to the inside of the back of the TV. The light reflects off the mirror onto the back of the screen. You view this refelected image from the front. Spiders commonly make webs inside the TV that appear in the picture. Dust Bunnies may get blown into an area and become stuck in the way. Sometimes a lite tap, shake or blow may remove this also.

Spot on JVC hd-ila screen

There are several things that could be causing this. Dust or foreign matter on the inside of the screen, dust or foreign matter on the reflecting mirror or dust in the optical block or light engine. The first two can be fixed by you if you can gain access to the interior. The third will require a technician. If you have had your question answered, please be sure to rate the solution. Thanks!

Dark picture (projection tv)

Hi Steve,
The picture is darker because the dust build up on the lamps or CRTs. I would suggest to leave the TV unplug overnight and clean the lamps using a screen cleaner that works better then windex and clean the mirror that reflects the video to the screen if you can get access to it.
