Check 'brightness' and 'contrast' settings in (usually) 'picture' menu. Use a recording (DVD etc.) of a dark scene to adjust the picture. My TV (not Sharp) has several pre-programmed picture settings. If yours has that, maybe one of them will be good. Otherwise, use manual settings.

Either the TCON board or the LCD panel has failed. Start by replacing the TCON board. If the problem persists, the panel is bad and the cost to replace it would be too high.

Voire 46" plasma tv- best color settings, to much white

The proper way to set flat screen tv's is opposite of old school CRT tv. First, find a movie with dark scenes and pause on a really dark part. Now set brightness only high enough to see some detail - no more. then go to a really bright scene and set contrast just high enough for good brightness. You may need to go back and forth a few times to get good setting.

Brightness and dark scene problems

you need to check your picture menu to verify you contrast is at max and brightness level is at approx 55% . if good , call for service and have htem check the setting on the screen controls. sometime they drift with heat, cold and age. when this happens, they usually have to reset the grey scale (black and white content) of the picture. Beyond that could be a defective red crt drive pcb or red crt or small signal panel.

It sounds like the master contrast has slipped. If you are confident with electronics, there is a little knob on the main board which allows you to set the master contrast. This is only applicable if the picture looks like it has too much brightness (like a white haze over the picture in dark scenes). Gently adjust the knob to set the correct contrast and you should be up and running. If that doesn't work, then your tube is on the way out.

If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.
