S2209W, power LED flashes before coming up

Hello,

I have an oldie, but up until lately, a goodie, the Dell S2209W monitor. I believe it's the first 1080 capable monitor from Dell when I first bought it in 2009. Been a great workhorse.

Bought it when I bought a brand new Dell Studio XPS 435T desktop that same year, running Vista (yes, that OS) but never did upgrade it to 7 later on and the original AMD graphics card, capable of HD. When that card went in 2015, I replaced it with the Nvidia GeForce 610 GT graphics card, which now lives on in a refurbished Dell Optiplex 9020 SFF desktop, running Windows 10 Pro when the Studio XPS died in 2019 when the original hard drive goes. At the time, the poor old original Dell had much else replaced but the power supply, the HD and memory/CPU so it was time to move on.

Anyway, repurposed the larger 22" Dell monitor, the Nvidia card, and then moved into the bedroom the Dell IN1910N 19" monitor beside it and put the S2209W to DVI, the IN1910N to VGA as that's all it had, running natively at their recommended resolutions, S2209W at 1920x1080, the IN1910N at 1280x720. The smaller monitor was hooked up to a secondary XP box in the living room for audio capturing and it now sports a very old 17" NEC LED 4:3 monitor and brought in the IN1910N into the office to run with the S2209W.

All ran great until a few weeks ago when the S2209W began having an issue. I power down the monitors at night when going to bed, but leave the computer itself running, never going to sleep. In the morning, turn on both monitors, both come up, but now, the S2209W sits there, dark, LED power light blinks for at least 2 minutes, until the blue Dell logo comes up, then a second later, the image appears from the graphics card. The image looks great still and the power LED stays lit. Now, it seems to be getting a bit worse, as it seems to take a little longer to come up.

Before all this, the lock/unlock would cycle and eventually disappear. That is hardly the case, and I was able to make certain it was unlocked for the menu functions. This morning (11/22/22) power LED blinked, then stopped, but was not looking at the monitor when the blue Dell logo popped up, if it did so, LED stopped flashing, but the screen remained black. A wiggle of the mouse didn't initiate a change. So I turned off, then on the monitor and it flashed 2-3 times, then saw the blue Dell logo, and the image came up.

What I've done. checked the DVI cable to ensure it was tight, seemed to at first, including the power cord, but moving the monitor around didn't cause a loose connection so that was out. I did find a VGA cable I had laying around and an VGA to DVI adapter and swapped the video cable, No difference, LED flashed at least 2 minutes before image appears.

Then went into the menu and set it from auto to VGA, no change there either.

So the ONLY other thing is the drivers for this old monitor and will any of it run on Windows 10? Or do you have any idea what may be at issue inside? I know this monitor is old, 13 years old, and has lots of hours on it but once the image comes up, the display is bright, clear and stable.

Thanks!

John.
