SOURCE: Gray spots on screen on a JVC HDILA model HD 56G 787

The HD-ila sets accumulate a lot of dust in the light engine. The worst offender is the little fold mirror just under the lens. I take my set apart about every 8 months or so to clean all the dust from the light tunnel and all lenses, mirrors, diffusers etc. The picture really regains it's pop when this is done. Unless you are a skilled technician though, I would recommend against attemptimg this procedure as you need to disconnect the individual color lcds. Check with a local service center to get it properly cleaned.

SOURCE: wega KDF-50WE655 has purple spots, support says wega engine bad

I have over 10 years experience in electronic tech support.

I know this isn't what you want to hear, but the problem you've described sounds like one of the circuit boards that control the picture quality needs to be replaced. The cost of the board would likely be in excess of $200. There are usually several boards in a TV like that that control the picture and when one goes, you can get anything from lines in the picture to poor picture quality from blurriness. The main question is do you want to spend $1000 to fix a used TV?

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please let me know if I can be of further assistance.

SOURCE: I have a 56" JVC rear projections HD ILA tv.

Turn tv off and unplug it. Take the access door off either side of the tv. Use a dust cleaning tool like a swiffer with an extension (or make one). Clean off lens (most likely the problem). I have the same thing that happens to my JVC 61". You can use a vacuum with extension if your VERY careful.

SOURCE: round black spot in middle of the picture/screen

Hi :-)

The round blotch your seeing on the screen is the melting of an acrylic lens inside the light engine. Its a design flaw which unfortunately Infocus will not stand behind. To fix this problem requires opening the light engine and putting an equivalent lens in place. This task is very involved, but this problem is repairable and you need a glass smith to cut the right size lens from the original.

The gray spots are caused by dust on your lens, very easy to clean.

Power down the TV.

If you open the right side access panel (right side as you are looking at the front of the TV) you can see it in the middle, it's not very big. Using a scratch/lint free cloth, gently wipe off the lens or use a vacuum to **** up the dust being careful not to actually touch the lens.

Replace the access panel and enjoy your spot free screen.

Dark Blotches


This is probably caused by dust, either on the mirror, lens, or possibly inside the light engine. There is a 5" dia hole on the side of the back of the tv where you can take out one screw and take the door off. this is just big enough for you to put your hand through to clean the mirror and lens. Hope this helps.

Canon 30D spots


It's 99% dust, especially if it appears mostly in smaller apertures (<f/8). To test it, select a small aperture (e.g. f/16) and take a photo of a blue sky. The spots will show consistently on the same location.

They're hard to clean, so chances are you just missed them. Try again, or, better still, send it for cleaning to a professional.

Dark spots on tv


I have the same TV, and I was getting the black spots on my screen as well. It is dust settling on the bottom mirror. Yoiu can call Mitsubishi and spend 150-200 on getting it cleaned, or you can do like I did and take the front panel off and the 10 screws around the edge on the back of the black plastic border around the screen. Then lift up gently and have someone hold the screen for you and gently dust the bottom mirror. I did this by myself, but it would be wise to have 2 people do it.
