Is it plugged in?

If you can open the cover of your monitor try to locate the fuse maybe the fuse is busted replace it.
if the fuse is blown or busted again there is short circuit in your power supply maybe the diode or the power transistor is shorted you need this to bring to the shop for services

please change i.f board if problem not solve thet means problem with lcd panel

try this test: put pc into hibernate mode and allow full cycle. if monitor ceases problem, then original problem may be with pc's video output only.

may i know the exact model # of your monitor..?

Grateful how? Neverminding that detail, perhaps your screen's backlight or the power supply for it has failed. There's nothing to do but compare your unit's operation with that in the Service Manual or that of an operating unit; this is complicated by the fact that components might send an OK signal back to the main controller, so removing the bad parts will not necessarily mean the unit behaves normally otherwise. It may be as simple as rinsing the cat barf out with water and D.I. water (but you would still have to open the thing up on towels to find out.)

Of course the main power supply might also be faltering. you can probe the supply (with a DVM or scope) to see how steady that is.
