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?
Ah, then the power supply is in the monitor. Not easy to swap out. I'd say it's either that or the backlight itself. Neither is really worth fixing. Sounds like you've got a DIY projector on your hands.

We've had a few similar symptoms at work, but with 24 inch screens, that simply required new DVI cables. 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.
I've been looking at a few DVD-R/VHS combo machines recently. They run about 200-300 bucks and are made especially for copying your VHS tapes to DVD. The Best Buy/Circuit City stores have been running weekly promos on 'em.
