monitor just kinda dies

My friend is having problems with her monitor. She has an AcerView 54e monitor and it occasionally just dies from time to time and goes black on her. Although the power light is still on, she cannot see anything on the screen. She says that when the monitor does this the same sound of static crackling that occurs when a normal monitor is shut off can be heard. The way in shich this is being delt with now is that she just shuts the monitor off for a while then turns it back on and usually the picture comes back for a while. If anyone knows why this might be happening and/or how to fix it please let me kno. Thanks in advance

 

The only thing that I can think you can try is to go to Control Panel/ Power Options and set "Turn off Monitor" to Never - this might stop it

 

Look i don't know if that is the solution but i have a similar problem with my very old monitor ( Hantarex 14" !!! )
When my monitor remains open for a lot of hours ,the CRT ( cathodic ray tube ) is getting very hot and the image begins to tremble and after a while everything goes to black and i cannot see anything . i close the monitor waiting for the CRT to cool for a while and then i turn it on . Well image is normal for a while and then it goes black an so on ...
things are getting worse when the climate is very hot ( for istance at summers )
To solve this problem , every time i feel the CRT getting to hot i place a table fan facing the CRT (the back of my screen ) and everything works really fine !! .

Sorry for my english

 

The first thing is to make sure it is well ventilated. By this I mean it is not closed in where the heat can't dissipate. Also check to make sure nothing is over any of the slots that let in and out. If it still does it, try it on another computer for a while and see if it still does it. It is a possibility the monitor is going bad also.
