Question about Panasonic PT-AE700U Multimedia Projector

1 Answer

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?

    Andy,
    ....so we know it's not the bulb/lamp. My guess is that it's something with the LCD - like when you press your finger up against the screen on your laptop (you get the liquid movement). It seems like it moves around very slowly on it's own...sometimes it's worse than others (even during the same viewing period).

    If cleaning it helps, please let me know what you did. I'm not one to normally take apart my gear (not skilled in those arts), but if what you do cures the problem, i'd love to know exactly what you cleaned, etc.
    thanks,

    bill
    PS: good to know that the bulb lasted so long. I kept the old one as a replacement just in case this new one goes kapoot.

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. Andy

There is a dark spot that is showing up on all my pictures and it's getting larger


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.

White fog "ring" around outer third of screen. Dark spots and a single white pinhole in picture as well.


If the model above is correct you are describing a bad optical light engine, about the most expensive part inside that set.

My SAMSUNG DLP HLT5675SX TV seems to develop little black spots all over the screen and after a while these black spots become bright white spots. In fact if a non-used Input is selected and the screen is...


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.

My JVC 56G787 is dark and bright is turned all the way up


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.

Bright spot on my 52hm95


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.
