Question about LG 47LG50 47 in. LCD HDTV

1 Answer

My screen has had, since purchase a weird look to the screen. It's as if there are set of curtains across the whole screen with various subtle folds with lots of shadows. It's sometimes not noticable-other times it can be very off-putting. And every now and then the volume seems to suddenly spike and then goes down to a lower level then raises the volume again very slowly. It's as if someone had fitted an attenuator.

I am using a Nikon D200. When using flash I can't raise the shutter speed any higher than 1/250. It seems to be locked there and I don't know how unlock it. Please help.


That's entirely correct. 1/250th is the fastest shutter speed you can use when using flash. Many other cameras can still only use 1/60th or 1/125. It's all to do with the two curtain nature of an SLR shutter: when you release the shutter, one curtain withdraws across the frame to expose and then a second one follows behind to shut off the light source. For exposures of 1/250 or slower on your camera, the second curtain does not start to travel across until the first one has fully opened, so you have a fully open exposure frame allowing the flash to reach every part of the sensor. At faster speeds, the second curtain sets off before the first one has finished and at the highest speeds it's so close behind the first that only a narrow **** is open to the incoming light as the shutter curtains pass across the sensor. If you fire the flash at these speeds the shadow of the first or second (or both) curtains will appear on the sensor and the picture will look like a narrow horizontal band, or if using fill in flash, it will look like a bright band across the picture.

It's immaterial though as the normal exposure rules don't apply with flash: the flash duration is typically anywhere from 1/4000th to 1/50000th and in that exposure time it outputs sufficient light onto the subject to enable a photo to be captured. As the flash is the dominant light source, the ambient light captured when the shutter is open for 1/250th is insignificant unless you're making a daylight exposure and using the flash for fill in purposes.

There are some specialist SLR and flash combos which will allow the full range of shutter speeds, but they do so by firing the flash multiple times very rapidly to ensure that there is flash light present effectively continuously as the narrow exposure **** passes across the sensor.

Compact cameras have shutters which work differently and which fully expose the sensor at all shutter speeds, so in that respect they can have a far more flexible flash exposure system. Unfortunately, they ruin it by having pathetically weak built-in flashes which are only good for very short distances.

My Minolta Maxxum 400si film SLR seems to have a jammed shutter and the shutter curtains seem to be mis-aligned (this would be because of the previous owner, not me) but the bottom curtain actually seems...


With the shutter curtain out of place the camera will not function. If it is only out a little you may be able to persuade the shutter blades to fall back into position. If you bend them, or if they are out of the proper tracks then the camera will have to be sent to a repair service for repair.

AaaaaaaaaaaaAFTER TAKING PICTURES IN DOORS WHY DOES IT GET BLACK ON THE RIGHT SIDE SOME TIMES NOT ALL THE TIME?


typically this is a problem with flash photography.
are you using flash?

the speed of exposure, the time that the film is exposed is controlled by two curtains that cover the film and prevent light from striking it. One curtain is across the film at the start, and springs open, then the second which was open, springs shut.
for 'long' exposures the first one opens time passes and then the second closes, but to achieve very short times, the second curtain starts to close before the first one has fully cleared the opening. so the edge of the second curtain can be traveling fractions of a second behind the first.
the result is that NOT ALL OF YOUR FILM is exposed to light at the same instant. If you have a flash go off during a fast exposure, only that portion of film that is exposes when the flash fires will get the proper amount of light, the rest of the film being blocked by a curtain. Most cameras are wired to fire the flash as soon as the first curtain is fully open and before the second starts to close. If you have a faster speed set in your camera by mistake, the second curtain has already started to close when the flash goes off. The black area on the right side is that portion of film that was already covered by that second curtain when the flash fired.

if you have the camera set correctly (typically at 1/60th or 1/100th sec) then maybe you should take the camera to a local camera store, and have the curtains timed...

Rear curtain won't close fully


It's a sign the mechanism needs a cleaning and lube. Temporarily you might try releasing the shutter ( without a lens mounted ) and locking the release button down. Then CAREFULLY from the back, put a little upward pressure on the metal curtain 1/4 inch or so, to twist the curtain slightly on it's shaft. Don't pull to far or you can do permanent damage. You should have a repair shop take care of it.
