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.

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.

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.

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.
