Check if one of the light tunnel mirror had detached, if lens are not well in place, or if there is a foreign object between lamp and lens.

    Check the lens try cleaning them if you see they are dirty, dirt is fist cause for spots.

    If the lens are ok, you will need to inspect the inside of the projector.

    Start unplugging power and remove the projector cover.

    Start inspecting the lamp, if the lamp had developed dirt or a burnt survace, it may need to be replaced.

    The tube, internally covered with mirrors, that projects light from lamp toward the lens is called the light tunnel. Check if one of the light tunnel mirror had detached.

    Check also if there is any foreign object between lamp and lens.

    If you do not find anything at first sight, then the lens may be defective and need to be taken apart , and reassembled, or entirely replaced.

My epson projector center is blurry

Hello, if it's mounted you may have never adjusted the "focus" on it before. Just slowly turn the end grey colored lens one way or the other with a stationary picture such as the menu on the screen, adjust it to where the lettering is the sharpest.....tks

My Kenmore Elite He3 dryer has no heat?


If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.

if you dryer is gas check out this gas no heat tip....

If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.

There is a line, like a shadow on the right side of the screen all the way up and down. What is that from?

Your TV uses a "Light Tunnel". A part which has various filters to create the proper "color" of light needed to produce the picture. Sometimes, one of these filters slips, causing a shadow to appear in a corner or along an edge. The appearance is this defect is more of a shadow and does not have a sharp, defined edge (like a letterbox image would). You can replace the entire light engine to repair this or just replace the light tunnel. The light tunnel repair is much more difficult... I would recommend a service call, as this is not a simple procedure. I hope this helps.
