Re: Dust inside the screen

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.

Picture problems

Two things to look at from rear with back off: one is the inside of the screen and or the large mirror in rear of unit--do not touch mirror.

second is the unit has a small lens (2-3 inches) the points up towards the mirror---dust or such on it will cause this--it can be cleaned with a lens cloth.

If the mirror has this (uncommon) the entire front of set would have to be removed (screen units) and that is not real easy.

If lens and mirror and screen are ok problem is INSIDE the optical unit that the lens is part of---on rare occasions that can be cleaned out with compressed air.

without seeing a photo of what it looks like this is all I can suggest.

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.

Mitsubishi wd 62527 has very dark picture changed

Clean the small front projection mirror. That mirror can get dust on it and will cause the projected image to appear dull and dim and cleaning that mirror will usually restore the brightness and crisp details in the image.

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.

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!
