[comp.sys.amiga] 1080 monitor problem

bugboy@Portia.Stanford.EDU (Michael Frank) (04/24/89)

Hello,
	For some time now I've had an irregular problem with my Amiga
1080 monitor.  Every once in a while, the screen jumps and I simultaneously
hear a spark from inside the monitor.  Apparently, the spark causes a
momentary voltage spike or drop, because every 1 out of 10 times or so
the computer crashes (the crash may happen in any number of ways).
	Does anyone know exactly what this problem is and how to fix it?
I've called local repair places but I can't get a unanimous diagnosis over
the phone, and I don't want to bring the monitor in to someone who doesn't
know what the real problem is and just charges me for doing something
useless.  Someone suggested dust buildup but I opened up the monitor
and everything I could see looked pretty clean.  So I now turn to the
Usenet wizards for help.
	Sorry if this subject has been beaten to death before, but I
don't have the time to keep up with the sheer volume of this newsgroup.
Replies via email would be appreciated.
	I really need help badly as the problem is getting worse, I've
lost work because of it, and I'm afraid it may damage my computer.

	Thanks,
		Mike Frank

When I saw similar problems at work(on Wyse terminals) the problem was the 
high voltage insulation breaking down, not dust.  The symptoms are the same,
but it didn't crash our computer as it was on a different circut.

The fix: out technician would reapply the insulation.  Check with a TV repair
shop (I'm assuming your 1080 is out of warranty) and ask them if they think 
this is reasonable diagnoses...
