If irregular it is likely a problem inside the optical light engine the set uses---it is possible to post a good photo here to show what it looks like, often that tells more than words.

SOURCE: JVC HD DILA 56G886. replaced lamp and now it shuts down after 10

we found that it is an auto shut off system on the TV due to over heating. The lamp, if not cooled correctly shuts down. We added a mini fan in the back and it seems to work fine now.

Have black dust looking spots on my screen.


Howdy;
Yes there is a way. The easiest for you would be to remove the back top of the TV. That will give acess to opt lense and mirror. But first check the Lamp and inspect the lense that the Lamp into. It does not take a lot to cause your concern. Use super soft cloth and wipe surfaces.

Good Luck,Big Irish.

Mitsubishi WD-62527. Dark picture.


That unit is a two mirror set. Meaning the light engine lens shines down onto a small mirror and that is reflected onto a large mirror and then onto the screen. Gravity being what it is dust and other contaminants cover the lower mirror. Moving the set would only aggrevate dust settling on it. To fix the problem the screen must be removed and the mirror cleaned. You won't believe the difference. It will be like watching a new tv.

Dark Picture


Sorry Don

Smoking absolutely destroys these TVs. Just like Teeth, the smoke gets inside and permenantly yellows the Light Prism. Since the Light Prism is responsible for passing light in these units, the yellowing dims and yellows the picture. There is NO fix for this.

Cleaning these is dangerous since all the parts have either a UV or Polarizing coating on them.

Again, I am sorry but this is the truth. On the other hand, try pressing the "Video" Button to see if one of these settings is any improvement

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.
