My parents have an Envision EN7220 LCD monitor, and a while ago, it started constantly power-cycling on and off. I forget offhand if I tried their monitor on my computer, but I did hook up my monitor to their computer and it worked just fine.
So they unhooked the monitor and that was that.
Anyway, today, I'm poking around Instructables and found cheap fixes to LCD monitors, so I looked up this issue, and it seems they're not the only ones (fixya.com) to have it. Tried the solution listed there (uninstalling display driver in safe mode, then rebooting so it could rediscover everything. Now, when you turn the monitor on, it works for about a second, then goes black. If you turn it off and back on again, it'll work for a second again.
I just updated the drivers, and now it'll stay on for 20 seconds before going black again. Any idea what could fix this?

It's just a plain ol' power cord. Just swapped it with another one, still doing it.

Other times, some of our white box PCs with cheap video cards couldn't continuously run DVI, so we had to swap them to VGA cables. |
