Black LCD Same issue. Powers up fine but lcd is black. Looks like it "sees" a little light around the edges but that's it. Takes black pictures. Can still see old images fine. It's like the camera went blind.

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open).

To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know

No picture but there is sound


think I may finally have the answer for the "black screen of death" for the 42" Polaroid LCD televisions. I was having the same issue with the screen going black after a couple minutes of being on. I would shut it down then turn it back on and it would work again for 5-10 minutes. On the "power board" which is the board on top, there is a little red light that turns on when the screen would go black. above that there are 4 little switches, the lower on says BURN. I simply switched that over and the television has been working for 2 days for 8 hours + each day. Hope this help. Let me know

This is called a dark shading error. All the LCD consumer sets have some visible degree of this effect. Some will be a little less or more than others even from the same batch in the assembly run. This has to do with the optical design quality of how the back-plane lamps illuminate the screen. The design and assembly tollerance of this area is very critical.

Normally, LCD screens don't show their best picture in a darkened room. The very black regions of the picture content may look a little washed out. LCD screens are best watched in a room that is lit, but not very bright. You have to consider that there is a powerful set of lights behind the polarized panel of the LCD display, and there will always be some breakthrough of light.

If you want a TV that is more like a CRT in its characteristics a Plasma would have been a good choice. The trade-off with the Plasma is that it does not have the picture sharpness of the LCD. A Plasma set is best watched in a darkened room.

If you have an LCD computer monitor, take a look at it in a dark room with a black screen. You will most likely see the dark shading errors. Only the very expensive production studio type LCD monitors have less of this error than the consumer sets, and they are not absolutely perfect.

Dark black spots around the edges of LCD TV


this issue is tape from the edge of the panel falling onto the screen.You will have to remove the cabinet and the panel from the bezel(front cabinet).remove the screws from the lcd outer edge. Take of the tape.Be very carfull of the ribbon cable that goes to the lcd controller and to the lcd screen itself. They break easy. If you do , its over. you will need a new panel. to much money and work. best to leave it alone.I have fixed it several times for people with warrentys. It is just anoying but will not hurt your tv.
