Title: Monitor immediately goes into sleep mode
Post by: Blondie1965 on February 20, 2004, 02:48:19 PM

When I turn my monitor on, the light is green for about 3 seconds and then turns to amber - sleep mode. My PC is only 2 years old. I tried 2 brand new flat screen CRT monitors and a brand new 15" LG LCD monitor. This happened with *all* of them! I cannot view anything on my monitor because of this, so it's impossible to change anything in the settings, etc.

However, I tried an older monitor and it seems to work fine on my PC. Does anyone have any advice? PLEASE HELP MEEEEEEEEEEE!

Clear  the CMOS (BIOS) than try booting up.

I'm having the exact same problem and have been trying to find a solution to this for the past 6 months...It seems many people have this problem, but noone seems to have a solution.  If I try to restart the system, the monitor power light will show green for a second, the monitor will flicker and the power light will flash yellow like it's in sleep mode...have tried other monitors and the same thing happens.  Sometimes I have to do a power down and power back up (sometimes 4 or 5 times) before the monitor will come out of this funk, but it always happens on a restart...anyone have any idea?

It's not the monitor, it's the video card or video drivers. The video card is sending garbage signals to the monitor, so it goes into sleep mode as it doen't "know" what else to do. The reason the older monitor worked is that it doen't pay any attention to those signals. Silly question, I know, but did you read the instructions that came with the monitor? Some have a trouble-shootiing guide, not restricted to things like   "check all the leads are connected...".

First thing to do is to reboot in safe mode, and check settings. too fast a refresh rate is a common cause. Other possible reasons are an IRQ conflict between the video card and another bit of hardware, NIC or TV card maybe.

Many people aren't aware that installing an updated driver for the MONITOR can often cure such problems, but concentrate on the video/graphics card. Go to the manuf. site, if possible, to see if they have any available.
