Hi, I’m new here, so I’m not sure if this is the right category. It’s not about a PowerPC, but rather the monitor for one.

I’m having trouble with one of my monitors. I recently bought a beautiful Apple Cinema Display CRT 21", but after what I would say was about 30 minutes of being powered on, I moved it, powered it on again for about 10 minutes, and then it suddenly stopped displaying an image.

?

I had only used the monitor for about 10 minutes when a friend stopped by. We had a drink in the living room, and when I came back to shut down the PC, there was no image. The power light was still on (green), but the screen remained blank.

After a lot of troubleshooting on both a Windows computer and a G5 Mac (where I could access display settings), I managed to get an image, but only at 800x600 resolution and under 75 Hz—and the image is completely squished horizontally.?See the attached picture.? https://imgur.com/a/4I7DOqH

My question is: What happened? Is it fixable?

?

Have a nice day!?

TL;DR:

My Apple Cinema Display CRT 21" worked fine for 30 minutes. I moved it, powered it on for 10 more minutes, then walked away. When I came back, no image, but the power light remained on.

After troubleshooting, I can only get an image at 800x600 under 75 Hz, but it is horizontally squished.

?

What happened, and can it be fixed?
