Asus VH232T: Backlight flashes very briefly, then stays off.

Tue, 21 Jul 2026 21:18:14 -0700

I got this display used, unfortunately it didn’t work right from the start. The backlight only flashes for a split second when turned on, then stays off.

Other than that the display seems to work fine, the image is definitely there (checked with phone flashlight), so I decided I want to try and fix it if I can.

Taking it apart was easier than I even expected. Unfortunately I couldn’t see any bad components on either of the boards (power supply and logic board, I assume), and I didn’t think to take any pictures at the time. Put it back together for now.

If anyone has experience with this model (or similar ones) and can point me to what exactly to look for that would be appreciated. I saw that other Asus models seem to have problems with the power supply? Where could I get ahold of a new one to try that out?

Edit: Took some pictures:

Dell U2711 Display: Dell U2711 display showing yellowish tinge

Sat, 18 Jul 2026 04:29:35 -0700

I picked up a Dell U2711 display in good physical condition, manufacturer in 2012, to use with a Mac Mini M4 running Tahoe (or other older Minis). The display boots up with a yellowish/amber tinge and no amount of brightning and adjusting contrast will get me to pure white say on an open text document. In Settings I can pick the U2711 but I'm not finding a way to calibrate it further. The monitor is connected via HDMI and set to YPbPr on the monitor controls. If I change that to RGB everything turns very pink. Same result in Settings on the Mac for Display. If I chose Generic RGB instead of U2711 the display turns pink. None of the other choices in those setting substantially reduce or improve the yellow tinge. So, as this is an older display it appears that something is fried inside like some kind of graphics board but I'm out of my depth here. Since I'm using it with a Mac I don't think that any driver updates are available for me. I'm not invested in this display because I got it for free :-) but it would be a handy upgrade for some of the other Mac Minis I have running. I like to tinker so any ideas about getting it restored will be appreciated. Once upon a time it was a halfway decent monitor. Thanks.

Dell 1908FPb monitor: Dell monitor shows a green line during boot screen even after replacin

Sun, 05 Jul 2026 16:36:35 -0700

Hello. I have a Dell monitor, and I noticed a green line/green tint appearing on the screen during the boot process, even before Windows starts.

I already replaced the VGA cable with a new one, but the issue is still there.

Since the green line appears during the BIOS or boot screen, I think it may not be a software problem.

How can I determine whether the issue is caused by the monitor itself, the VGA port, or the graphics output of my computer?

Unfortunately, I don't have another monitor or computer available for testing.

Any troubleshooting advice would be appreciated. Thank you.

While gaming my monitor display went black and wouldn't come back on. Tried on multiple other devices using another cable as well but still no image. Not even the menu will show up when clicking the buttons on the monitor.
