It's bust and it's out of warranty. Try a repairman (may be more money that
the CRT is worth) or order a new one.

 

Yes,u all right.I called IBM,they asked for Purchasing doc/Warranty
which I don't have as I bought it from garage sale.
Sometimes a minor fault can be rectified,so thats why I posted my
question for help,moreover it's good to get involved in troubleshooting
to get gold out of old.

 

Sure. Remove the case, hook it up to your computer, fire it all up. Play
with the little potentiometers on the boards in the monitor till you really
screw it up...er...I mean...find the one that adjusts your pincushion
problem.

 

Oh - and watch out for that high voltage thingy...it'll shock your willy off
;o)

 

Signed. Willyless. <g> It`s only a few K. <giggles>.

 

Yeah - I know. Color TVs are around 27,000 volts. Monitors probably aren't
much different. I've been zapped a few times over the years <grin>. But the
worst zap I ever got was while working on a microwave oven. It's only 4,000
volts IIRC, but the capacitors are a whole lot bigger. Zowie! Had to pick
myself up off the floor - 6 feet away ;o)
