My plasma t.v model lnr328wx comes on with sound but no picture.


I don't know if your using an antenna or other source but one quick test to see if your TV can display is to push the display or menu function. If your screen stays black then your TV has a problem and needs serviced. If your screen shows a menu then you may have a problem with the source video.
Try to elaborate more on your hook-up, it can be most helpful in solving display problems.

Toshiba 32a43 32' picture garbled mess


If you can get the tv to display the blue blackground(usually happens when there is no antenna or cable feed to tv) check to see if the whole screen is a solid blue, if it shows discolored areas around the screen then you might have to "demag" the screen. See if you can rent a demad coil from a tv shop and with tv on turn the coil in circular movements all over the front of screen till blue is solid.good luck!

HD50LPW42 screen is black with antenna inputs


It sounds to me like you have a tuner issue, I have seen this before. If you have a good picture from other sources and they have the same antenna input, the tuner is suspect.

I hope that this helps you solve your issue.

4.14.1 Understanding Viewing Features
Your LCD HDTV features four viewing modes and Picture-In-Picture (PIP)/Picture-by-Picture (POP) mode.
You can switch viewing modes using the remote control.
4.14.2 Viewing Modes
Normal Mode
The original 4:3 aspect ratio (1.33:1 source) is preserved, so black bars are
added to the left and right of the display image. Standard TV broadcasts are
displayed with a 4:3 Aspect Ratio. Movies in 4:3 Aspect Ratio may be referred
to as pan-and-scan or full frame. These movies were originally filmed in 16:9
(widescreen), and then modified to fit a traditional TV screen (4:3).
Wide Mode
When watching a standard broadcast or full-frame movie in this mode,
the display image is stretched proportionately to fill the TV screen.
When watching a widescreen (1.78:1 source) program or movie, the
display image fills the TV screen. If you are watching a widescreen
(1.85:1 or 2.35:1 source) program or movie, there will still be black
bars at the top and bottom.
Zoom Mode
When watching a widescreen (1.78:1, 1.85:1, or 2.35:1 source)
program or movie, the display image is zoomed proportionally to fill the
width of the screen. The top and bottom are cut off to remove most of
the source material’s black bars. This mode is good for programs or
movies with sub-titles.
Panoramic Mode
When watching a standard broadcast or full frame movie in this mode,
the 4:3 Aspect Ratio (1.33:1 source) display image is stretched
horizontally on the left and right sides to fill the TV screen. The center
of the image is not stretched.

Note: Viewing modes are saved based on input. For example, you lasted watched a DVD in widescreen
mode and then watched TV in standard mode. When you switch back to DVD input, the viewing mode
will return to widescreen.

Does the menu show up on the screen, or is it totally black?
Does the camera take pictures and behaves as normal (apart from black screen ;)?

If the menu shows up then I'm afraid it's most probably something serious- like dead CCD or failed shutter (probably the latter-LX2s are not famous for failing CCDs). Failed shutter is easy to identify. You would normally hear a faint mechanical"click" when taking a picture (make sure you disable sounds in your camera). If you can't hear anything then the shutter might be dead. In cases like this I normally suggest getting a donor camera from ebay and replacing the lens (the shutter assembly is inside the lens but it's much easier to replace the whole lens).
Good luck,
Raf
