Re: 2 seconds to black on HNC IH252 HPB Monitor

I'm having a similar problem. When the problem began, every few days the monitor would go to black for a few seconds then come back up and work fine until it repeated to process again in another few days. While the monitor went black, I could hear a hissing white noise coming from the back on the side of the power board. When the monitor came back online, the hissing ceased. Yesterday, The monitor blacked out and would not come back on. If I powered it off and then back on, it would remain lit for 20-30 seconds before dying again....
