[comp.sys.atari.st] HELP: mono-monitor problem

ravi@mcnc.org (Ravi Subrahmanyan) (06/16/89)

I have a problem with my mono-monitor, and I'd like some advice.  My ST
has been completely trouble-free for 3 years, but since last week, the
display has a problem.  It starts out Ok when I turn on the system, but
after 10-15 minutes, the characters at the top of the display become
very big, and the bottom of the display is compressed.  If you look at
the scan lines, they appear as follows, spaced out widely at the top,
and squeezed together near the bottom


	NORMAL			PROBLEM

	-----			-----		Top of screen
	-----				
	-----			-----
	-----			=====		Bottom of screen

The problem is not gradual, but it happens suddenly; the screen
flickers, and then is messed up.  Sometimes, it flickers and becomes
normal again for a while, then goes back to the weird state.  This does
not happen if I hook up the ST to a TV,  so I suspect the problem is in
the monitor.  Does anyone have any experience with something like
this?  I'm quite willing to muck around with the monitor, but I'm a bit
wary of the high-V stuff.  I'd appreciate any hints as to what could be
wrong, and also advise on where I could get it fixed (we don't have any
dealers in this area!).  Does Atari fix these things, if I were to mail
it in? Thanks in advance,

ps: If someone at Atari reads this, I'd appreciate getting info. on
repairs.  Thanks.
