Nowadays i m facing a new problem. My PC's monitor blinks(it goe blank
and after a second the screen revives), this heppens atleast 3-4 times
an hour.
Can anyone help me out of this problem??

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.

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 ....
