Dead IIGS Monitor ?!?

[rankins@SYBASE.COM (Ray Rankins)]

It seems my GS Monitor has finally died.  For a while now, the picture 
would waver and sometimes black out, but a firm tap on the side of the 
monitor (or sometimes just turning it off and back on) would restore the 
picture.  Sadly, the picture blacked out last night and I can't get it 
back.

When I turn the monitor on, I can here the high frequency sound that a 
normal monitor makes, but the picture is completely black and the LED 
power indicator on the front doesn't light up.  

Does anyone have any idea what may be wrong with it?  Has something 
possibly just come loose that needs to be reseated or resoldered?  
Anyone else experience similar problems with their monitor?

Maybe I should just give it up for dead.  It is about seven years old.  
Maybe it has just expired after a normal lifespan?

Thanks for any assistance,
Ray
