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

Hello,
I have a JVC HDILA model HD 56G 787. I love this TV more than any I have ever seen. However, I have recently (in the last couple of months) noticed slight gray spots near the middle and near top of the screen. The spots are not TOO dark, but can be seen on a white or light colored screen. It almost looks like there is dirt or dust on the screen, but the screen is spotless. Have you heard of this, and what do you think can be done about it? Also, the lamp has been replaced about 2-3 month ago, but it think that it was doing this even before the lamp was replaced. I appreciate any insight. Thank you.

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.

Spots on the screen/picture can be caused by three things. Dust on the inside of the screen, on the mirror or in the light engine or optical block. The first two can be corrected by you if you can gain access to the interior. If it is the third (light engine. it will require a technician. If this answered your question, please be sure to rate the answer. Thanks!

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.

Talk to JVC as I have suggested and this is likely a known problem: loss of any color, picture upside down etc requires a upgrade to correct and I have seen about twenty sets with their name like this with this kind of problem.

I fixed it!!!! If you can open one of the sides (on the JVC there is a little door with a screw), then you can clean the projector lense in the middle on the bottom. It kind of looks like a big light bulb. It seems there is just dust on the glass that is projected onto the screen. We had a big gray spot and cleaned it with a damp glass cloth and Ouila! It disappeared. I scored MAJOR brownie points with my husband for this one! He wanted to replace the TV!
