There is a burn spot on the light filter on the blue lcd. you can call a sharp service center to purchase the part, but it's extremely involved to replace.

Can't bring into focus the entire image. Corners defocused and have green/purple halos.


If it is a known problem, then it is a manufacturing error. They have just admitted that is a MISPLACED washer. Have Optima repair it free of charge.

Blue dots on black images


I can tell you that I had my plasma screen replaced in the 4th year. The tech told me that the replacement panel was much more reliable. You may be looking at replacing the plasma panel...(which may be more expensive than replacing the whole unit??).

Canon power shot sd1000 black dot on lens


If by saying the upper right corner of the lens you really mean that there is a dark spot on each image AND the rear display, there may be dirt or dust on the lens itself. Clean the lens with an optical quality cleaner. Do not use paper towels and Windex or the like - as paper towels can scratch the lens.

It is also possible that the dark spot is a "stuck pixel" on the image sensor inside the camera. There is no way to repair a stuck pixel outside of replacing the sensor. Any dark spot (regardless of source) can be edited out by using image editing software. This will allow you to to make the dark spot less noticeable - or practically invisible.

If the dark spot is on the rear display only, it can also be a result of a "stuck pixel" on the display itself. This should not show up an images, but only on the display. There is little that can be done outside of replacing the entire rear screen.

There are other things that can cause these problems, but those listed above are the most common.

I hope this was Very Helpful and good luck!

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

Blue out of focus; casting blue "glow"


Try changing the coolant in the blue tube. Contaminated coolant will give a halo look to the affected tube and you will experience difficulty focusing that color.Phillips/magnavox's blue is the tube most often affected with the contaminated coolant issues.
