Not enough info. CRT type monitor? or LCD type ? Power indicator goes out /
changes colour ? Can be got back by thumping the unit ? Suddenly started
happening ? Getting worse or staying the same ? Any physical sound when it
goes off / comes back ? Goes off / comes back on quickly, or fades up / down
? Picture is perfect as soon as it comes back ?

Most likely problem, if its a CRT type, is a bad joint, although it could be
the power supply starting and stopping. If an LCD, it could be that the
backlight inverter is intermittently stopping.

Could be something as simple as a loose connection to the back of the
monitor or computer, have you checked it? :)

FWIW, I have a 2 year old monitor in the garage that started flaking out
on the bottom bar and just needed a whap on the side would get it to
come back. I am suspecting a no lead ROHS solder causing a bad joint.
My 'old' 2000 Compaq CV715 may not have the latest features, but 'it'
still works and does a nice job of heating the room, good in the winter
but very bad in summers that often hit 110.
I would be suspect of anything newer than about 2 years because of the
'Tin whiskers' problem and crappy lead free joints.

had the same .. started getting green screens and loss of video


The small square board located at the back of the tube, that
combines the tube socket is a good place to start looking for 'dry
solder joints' ..... close inspection with a eye glass will most
likely show them up ..... re solder and proceed to tap with insulated
'wand' while looking at the screen , you should be able to locate the
rough area ... re-solder and repeat till tube stop's flickering ....

I agree with the initial approach of the CRT board, but that is not it,
since only the bottom 50 lines or so are affected, losing sync, so it is
probably on one of the main boards. In 1982 I tried the TV repair
business and opened a shop just about the time TV's became throw aways,
bad timing.
I have also been nailed by the 25,000 volts on the big screen sets, and
after being kicked across the room once I got real careful. If it isn't
a solder problem it may just be a thermally sensitive chip, and if it is
too much work I will take it to the local church and buy a new LCD
monitor for less heat.
Thanks though,

Yeah,
They will probably just put it in the dumpster.

You are most likely correct, a few hours and a working monitor.
