LCD keeps going on for like one minute and then turning off into power saving mode?

I'm running dual screens, the secondary screen is an LG Flatron 19" LCD that keeps turning on (blue light) for about a minute, and then it goes into power saving mode (orange light). It keeps doing this over and over. I tried another power cord, rebooting, and redoing the connections to and from the computer and monitor to no avail. Nothing has been changed on the computer lately, I've had this setup for like 3 years, and it just started doing this today. It's connected via DVI. Is my monitor shot?

you try switching primary and secondary monitors? See if it's a bad OS update glitch?

I've seen around a hundred LCD's do this, though they were all HP brands (I work in an environment with a couple thousand of them). All were shot.

That being said, some of them had no issues with DVI but had the fail with VGA.

I'm betting bad caps in the power supply.

I had a similar problem with my sammy 204b. Just before I repaired it, it would take 5-10 minutes to "warm up" to an image from the off state. And once there was an image, it would take about 30 min. for the backlight to reach (almost) full brightness.

I googled, and found it's a common problem.

The new caps I got were from Fry's electronics, and they weren't exact replacements. One of them was quite a bit bigger than the original (it had a higher rated voltage), so I had to make it fit. It was a large axial cap that I had to lay flat and slightly extend the leads to the radial solder holes. Whatever. It worked. And I didn't have to dremel or modify the rear RFI/EMI shield.

Sounds like the inverter board. What finally did in my original 2000FP after several years of awesomeness. I paid $1200 for that sucker

Depending on the model you can buy replacement parts online. If its a cheap TN panel though, just trash it.

I've had automatic updates disabled since I had SP3 with updates slipstreamed into XP. I tried switching it to be my primary monitor, and also switched it to VGA connection to no avail. In the original config, when I hook another monitor up the same way it works just fine, so I assume the LCD is just fubared.
