Dell UltraSharp keeps restarting on standby

post #1 of 4
Thread Starter 

I got 2 dell ultrasharp lcd screens out of a local scrap yard one was a 17" the other was a 19" I paid $2 for them... On the 19" the panel was smashed, the 17" was not but had holes in the top polarized layer of the screen. Both did nothing when they where plugged in.

After opening them I could see there was lots of rust, they had been out in the weather for a while, but right away I could see there where bad caps on the power boards so I replaced them and somehow they both came back to life.

The 17" had white dots where the polarized layer was broken but I fixed that with clear tape and some polarized plastic lol.

As for the 19" there where random colors all over the screen. The panel looked like it was hit with a crt screen because it was that is what was on it in the scrap yard..

so later that week I found someone on Craigslist with a broken 19" Samsung lcd screen, they gave it to me for free because they where about to trash it.

this monitor did not have bad caps it was the inverter itself for the backlights that was bad so I took the 19" panel and connected it to the dell board it worked.


Now here is the problem when the computer tells the screen to go into standby the screen goes off then restarts and shows the dell ultrasharp logo then goes back off then comes back on again in a never ending loop until I hit the off button or move the mouse to make the video card output the display again.

any ideas?

edit: here is a video of the problem.

I bought my Dell UltraSharp's (three 30") new off of their site, certified seller.
Since then I had no problem with them whatsoever.

Your problem here could be:
1. Graphics Card Driver (ATI's drivers usually have lots of problems)
2. Graphics hardware is physically broken?
3. I suspect this is connected by VGA-DVI by a transformer on the output of
your card? That could be broken.

Besides that I don't think anything else should be a problem.
Dell UltraSharp monitors themselves are quite sturdily biult.

The computer that the screen is connected to has a Nvidia card...
and it has nothing to do with the computer at all.

there is something wrong with the monitor I just thought maybe someone here has seen this problem before and might know how to fix it.

#1 Have you looked in the device settings and troubleshot it? Start>Control Panel>View Devices and printers>Right Click Monitor>Troubleshoot. It's worth a shot.

#2 You're on Windows 7 so you could also try disabling/removing it and re-installing the driver to see if it gives a message like "This Did Not Install Properly."

#3 Maybe change the Power Settings?

I'm no expert, sorry if this doesn't help; but, these are what I'd try....

Good luck.

Awesome grab for 2 bucks.
