IT/Monitor advice please (issue)

[CMAC]

turn on the pc and the LG monitor 'on button' flashes constantly and there is no picture- pc seems to be running in background ok (I think).

checked all cables connected ok and after a few pc reboots and disconnecting monitor power and reconnecting twice I see flashes of an image occasionally. Then sometimes after a few mins of this its back to normal.

Is this a monitor or gfx card issue or is there something obvious the IT experts on here have seen this before?

Try plugging another monitor in. If still the same, then gfx card kaput.

51" TV and humungous hand built PC- neither are near each other

Is there a second graphics port on the pc? If you have a separate gfx card, the motherboard may also have onboard gfx which will work with the native windows driver. If not, boot in safe mode, which will disable the gfx card driver and again use the windows driver. Will at least eliminate a driver, rather than hardware issue.

Is this on the main graphics card, or onboard graphics? Either way if your monitor is working now I would'nt think that's the problem.

Check the VGA / HDMI cable. They break quite easily.
Update your VGA's drivers after that

Sounds like a driver issue. Download the latest driver for your card from manufacturers website. Then go to device manager, then display adapter, right click and choose uninstall. Then reboot, there should be a 'new hardware found' message. Then install the driver you downloaded and reboot again.
