  1. 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.
