my monitor goes blank,what could be the problem,after switching it off itcomes back after 10 0r 15 mintues.
Try using another moniter. If it does again then its the display card problem.Other wise your moniter's picture tube is epired/have to get a new one.
just change ur monitor, not expensive these days, never try to open it by urself, its hazardous, danger of severe elec. shock. btw, i think ur CRT has become problematic (i guess u r not using LCD).
thanks for your reply,iwill buy a new monitor,hope that will solve the problem.
