How do I get rid of the shadow that appears to the left of the projected image ?


The shadow is caused by projected light from the unit outside the image field. I have the same problem, and I just tend to ignore it. I have tried various settings and sizes to minimize the effect, but some shadow always remains. This is true with any projector.

If it is the lens you have other problems that would let it get that hot. Can't be sure, but I would first check the bulb to make sure it has not smoked. If so it must be replaced. When handling the bulb let it cool down or you can get severly burned. Never let your skin touch it or the oils on your skin can damage the bulb. I usually use a t-shirt or something to wrap it in while handling it or you could just wear cotton gloves.

My unit seems to work fine, except there is a dark shadow covering the right third of the projected image. Is this a sign that the bulb is going out?


this is the light tunnel needing to be adjusted or replaced because is has collasped due to the heat given off by the lamp during the life of the projector.

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.
