IBM G50 Monitor Repair Info Needed - HELP ! !

[Getafix74]

I have got an IBM G50 monitor, which works well some of the time.
Every once in a while it looses the picture and the screen goes dead.
If I hit it on the caseing just behind the tube then it flickers back
on for about 3 seconds, then goes dead again. Once this happens I have
to wait for it to cool down again, abot 2 hours wait, then I just pray
it works!......sometimes it works, sometimes it don't!!

I have looked around the net and it seems that it may just be a
resistor or bad soldering, has anyone got any ideas? but i'm not sure
how to tackle it!

Can anyone help cos I don't want to get rid of the monitor, and don't
mind having ago at fixing it.....

Main board likely needs resoldering! Try in the
horizontal hold, & power supply areas! Rono.

I have the case open now, where do I look for the horizontal
hold?.....i have not really done this before! i have had a good look
for loose or broken soldering, but i cannot see anything! Would I be
able to see anything like that? or do I need some equipment?

The little green LED at the front always stays on.....does that mean
the power supply is OK?

Occasionally it makes a really annoying high pitched whining.....does
this mean anything?

Thanks for replying, by the way! appreciate the help!
