Hi, When I switch my computer on it works fine. However the monitor wont stay on for more than 3 seconds. The LCD light comes on but I have to turn the monitor on and off to get the 3 seconds. A couple of days ago if I was really quick when I had the 3 seconds if I clicked on a programme in the start menu it would then stay on until I switched the computer off. Any suggestions guys I sooooooooooooo need my computer.
Thank you x

reported that the monitor lights for only a few seconds at startup and that a very quick click inside Windows once made it stay on. was right to suggest swapping monitors and trying the suspect display on another PC — that simple split-test is the fastest way to tell whether the fault is in the monitor or the computer.

A short, practical checklist that follows that split-test:

  • Swap the monitor with a known-good screen and note whether the problem follows the monitor or stays with the PC.
  • Swap video and power cables, and try every input (VGA/DVI/HDMI) the monitor and PC have.
  • Boot into the BIOS or watch the POST screen. If the panel goes dark before the OS loads, the monitor hardware is more likely; if it dies only after Windows starts, drivers or power-management settings could be involved.
  • In a dark room, shine a strong flashlight at the screen while it is “off.” A faint image means the backlight (inverter or LED driver) is failing; no image and a “no signal” message points at the video feed/cable/GPU.
  • Note the monitor power LED behavior (color, blinking) and any clicking or smell from the monitor/power pack.

Common hardware causes are a failing internal power board, bad capacitors, or a failing inverter/LED driver; external power bricks can also fail. If the monitor is under warranty, contact the maker. If not comfortable with mains-voltage repairs, a qualified repair shop is safer than opening the monitor; capacitors retain charge and can be hazardous.

if you have a different monitor try it and see if you get the same problem or if you have another computer, try the monitor in question on the other computer.

if you try a different monitor and it works then the problem is with the monitor, if a different monitor does not work then its with the computer

if you can try what I suggested and post your results
