Television and Home Theater

Mitsubishi Projection TV--- Trouble free since purchase in 1995.

Recently started showing slight jitter in magnitude of vertical deflection for several minutes after powering up.  This jitter evidences itself as intermittent switching between full vertical raster size and approximately 5% reduction in amount of vertical raster size.

This jitter disappears after the TV has been operating for duration of 5 to 6 minutes. 

Can't get my TV unlocked.  Recently purchased new remote and tried the #9+Q.V. keys and it will not unlock as told by the manual.

Any ideas besides "throw it away"?

Sharp 32LW-92H  Image will not adjust to fit screen. 

The controls only allow you to adjust the vertical height of the picture - therefore we either lose the top or bottom of the picture.   The picture seems too large for the screen and we lose substaintial sections of picture on all sides. It doesn't matter which format you are in - it will not ajust to fit.

The picture is also being distorted -pulled/curved to the bottom left corner.
