My picture brightness is uneven - there is a persistant bright field on my screen.
Starting about a month ago, a growing bright spot (where too much light is coming through) appeared on my screen. my lamp was at the end of it's life ("replace lamp" instruction would show up whenever i started the projector up - i checked, the lamp was about 2800 hours old), so i thought that was the problem. I replaced the lamp successfully, and the picture is better - but the bright spot (which bleeds from top to bottom of the screen, about 1/5th of the width) is still there.
so...it's not the lamp...but what else could it be?

I have the exact same problem with my AE700. It a started about the same time, around 2500 hours for me. I lived with it untill I could afford a new bulb which arrived yesterday. The old bulb was still working at a 3603 hours when I installed the new one. But the new bulb didn't fix the problem for me either. I may try to take it apart this weekend and give it a good cleaning.

To make sure this spot is where I think it is, on the sensor, You should put the camera in manual, A priority and whose the highest value. Shoot in bright light a complete white paper.
Then evaluate the picture on the monitor. If the spot is clearly viable the spot is on the sensor. With a fixed lens on your powershot, you can't repair or correct yourself. You should contact Canon. Don't tell Canon, you were in a moist environment. Perhaps a mould is growing on the sensor.
It is the chip that controls the millions of mirrors inside the tv. If they are black, they are stuck closed. If they are white, they are stuck open. I JUST had the same the same thing happen with mine. I bought it 3yr and 2 months ago and I had an extended warranty on it for 3 years. Well, needless to say, it was out of warranty and I was pissed. The store I bought it from suggested I call Samsung. Which, I did. They asked for the model number and told me that my model (hlt5675sx) was one of the ones that is covered becasue they had a problem with the chip. Within 2 weeks, my tv was fixed by a repairman who came to my house. It works perfectly, now and it didn't cost me a penny. Good luck.
This problems are on the video board,that connected to the CRT.The video IC inverter,all the capacitors around it.Some of the capacitors,that help to divert the colors are dead.Don't mess with the CRT Yoke,put it back to the original mark and tighteen it before,u misalign the three colors guns for good.
Sorry, pero tu problema no tiene solucion, solo por garantia...... but I have something for you.... 1. unplug the TV. 2. press and hold ch - 3. conect the plug again (green ligth on) 4. release ch - (service manu apear) 5. with remocon press down two or three times (find something like mp3) and change value from 0 to 1. 6. press exit 7. connect USB with pics and mp3 music. 8. check the pictures and.... the music start...
note. the USB slot must be empty before unplugged the cord.
You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

can see it in certain lighting
and even when the TV is off! It will appear lighter than the
surrounding areas at times and can be annoying. I called Toshiba and
had a service man come out and even though he acknowledged that this is
common, Toshiba will not replace the screen.
