Must unplug and replug monitor after sleep or startup

[robang13]

Hi,
The last week my monitor has been hissing and has now started to remain black after startup or coming out of sleep. I have to unplug and replug the VGA cord a few times before the screen comes back on. It tries to come on on startup but all you hear is this loading hiss and a quick flash of screen. After I get it working it works fine and will even come back on if I play with the on off button. I have already replaced the VGA cord with a new one so that's not the issue. I am running Vista 64 Premium Home on a HP pavilion. I've had the monitor for 4 years with no issues. I have not updated , installed or changed anything before this started. Any help will be appreciated.

Hello robang13,

Have you tried to update or re-install your display driver through the device manager?

Do you mean my NVIDIA?

After I get the monitor to work it stays on. Do you think this is a driver issue? Why is there this hum that was never there before?

It may be your Power supply going or a Transformer that has broken Does this happen with any other Moniter?

I already changed the power cord and the VGA cord. I'm going to pick up another monitor tonight to see if it's just this one. Just seems weird that it works once powered fine.

If there's a humming sound that was not there before it might be just that monitor.

But yeah, if you have a nVidia display adapter then go ahead and update /re-install it.

Yep, seems like it was the monitor. Of course it came out of warranty just 2 months ago!!
Thanks for everyones answers!!
