subject: Somewhat OT: Sony monitor brightness problem and solution

This is not an OS/2-specific problem, but just in case any of my fellow 
OS/2 users have the same problem (Nah! You're probably all smarter than I):

Many months ago, the display of my 19" Sony Multiscan G400 monitor 
turned very bright: even with the brightness set to 0, it was way too 
bright, areas that were supposed to be black were a greenish color, and 
the flyback lines were clearly visible. Pressing the Reset button reset 
the screen sizes for every resolution but did not touch this particular 
problem. Degaussing didn't help either.

I assumed that some internal component had gone bad but couldn't figure 
out how to get the case open -- and, yes, I know all about the very high 
voltages ("KillerVolts") that can still exist inside a monitor or TV 
hours after it's been turned off.

I looked for and eventually found on line a training manual for service 
technicians, but it assumed that the case had already been opened and 
didn't explain how to do that.

Having pressed Reset again and messed up all the screen size settings, I 
brought up the menu again and fixed all those settings, then noticed 
another menu item, "Option." This was the menu with Degauss as a 
sub-option, also moire correction. Then at the bottom I found another 
option: "Image Restoration" I had never noticed before; thinking, "I 
wonder what this does?" I invoked it, and the screen went totally white, 
then after several seconds restored my old faithful OS/2 (actually eCS 
1.14) desktop with everything looking much darker.

So now my monitor is back to normal, just when I was thinking of 
pensioning it off and getting one of those trendy new LCD monitors with 
deep rich colors (and fuzzy text -- at least on most of the ones I see 
in the stores).

Hope this helps somebody.
