its been a long time probably 6 months since i am having this problem. that time it used to be rare but now its more frequent. while i am doing anything my monitor goes black though not completely but i cannot see anything properly . i press the power button on the monitor and start it again and it works fine for few seconds but again the same sometimes when i restart the monitor it works great for some hours but then it happens again . if it helps i now take out the power cord that supplies to my monitor and then put it back and it somehow works better than switching off and on the monitor from the power button
my sys info if helps :

Solution
^^ You are probably right. OP please check with an external/different monitor. if the screen stays bright on external then it most likely is the backlight or if its CCFL then the CCFL power "driver" (a little PCB that works the fluorescent bulb). You can usually find them on ebay for pretty cheap and are pretty easy to install.

thx i may check that out

it depends if it is the backlight itself or the power driver for the light. The backlight is built into the screen so you would need to replace the whole screen. if it is just the driver card that is usually cheaper and easier.

Is you machine a laptop? I can't work it out from your OP.

am in india and i don't trust 2nd hand parts around here

sorry, but in truth you probably would have great difficulty sourcing the part for your fix anyway. and it would be second hand too. So whatever you want to do is fine.

The cheapest easiest solution is to find a cheap old monitor that is working. I have seen 17" flatscreens here in the UK for £15. I appreciate that that may be hard for your to come by/justify. but you would be paying that for the part needed here anyway.

If you don't mind telling me roughly where in india you are I will try to find something on OLX classifieds in your area. It looks like you can get super cheap monitors there just like gumtree here in the uk or craigslist in the usa.

the first thing is it is not the money that matters but the monitor my father holds me responsible for anything that happens to my computer so i cannot replace the monitor i want the parts to fix it and the second thing is i don't want to waste money on any part that won't do any good to my monitor >.< oh and i stay in kolkata,west bengal region help if u can

it is the electrodes in the backlight/driver. They wear out over time. If the resistance increases as the electrodes wear out the driver strains more to compensate. over time either the electrodes get so worn that the backlight fails entirely, or the driver breaks after repeated strain.

It works exactly like a fluorescent light bulb (the long thin ones) how many times have you seen a flickering one of those? sometimes they flicker a little, but they eventually get worse and worse until they don't work at all.
