Monitor LED flashing just before windows logon - VP930

JIM_BOB7813 · 22 Aug 2008 at 10:56

My monitor works fine, and turns on quickly when I power up my PC. But when windows finishes loading, and changes resolution to get to the login screen, there's a few second pause where it shows a black screen (like normal) but during the pause, my green LED flashes. I don't recall it ever doing this before.
It just did it this morning on first boot, but when I rebooted and tried to video it, it didn't flash.

Any ideas? Monitor is a Viewsonic vp930 btw.

It's getting worse!
Monitor is black all the way through booting, and takes about 3 mins to actually display anything from when I first turn it on.
Pressing the power button just makes the green LED flash, so I can't turn it off (while it's still trying to "boot" itself) without hitting the rocker switch.
RMA time methinks!

My VP930 appears to bo on the way out too. This afternoon I noticed that the desktop had started to 'break-up', vertical lines had appeared, pixels flashed and colours look washed out.

I did all the regular stuff such as reinstall monitor and video card drivers, under clock the graphics card etc, but to no avail. I run two monitors for a 2 screen desktop - I swapped the inputs over to rule out a DVI problem or video card issue. The problem persists on VGA and the other screen is absolutely fine.

I've had the screen for a couple of years now but I think it's pretty much curtains. Anyone know how long you can RMA a product? Is 2 years out of warrenty for something like this?

3 years (swap) warranty on vp930, BUT I was told today that they don't have any in stock and need to wait for them to call me back when they get one in. I've read quite a few people on the forum complaining of their VP930s failing, they don't seem to be built very well.

Thanks. I'vd just sent them an email detailing the problem.

Sometimes the video card can be the culprit. I had similar problems, turned out it was my vga card.

I don't think it can be the video card as the problem persists if I run the monitor through the 6800Gt's VGA port. The second monitor I have rigged up (an LG Flatron 1811s) works fine. I've just tried it with a laptop through the D-SUB and the problem remains - not a graphics card problem then!

I think it's a problem with the rendering engine on the tft, not the screen itself, as when I move a window around in Windows the 'sparkles' and flashes move with the window! Anyway, they're going to RMA it as soon as more are in stock.
