I received this off eBay yesterday and the seller had showed images of it working. The CRT shows many signs of life, I hear static when it turns on, a sound when I switch resolutions, the degaussing sound when it turns on, the indicator LED stays when its receiving input, but it just stays black.
It has VGA and BNC connectors at the back but the problem is the same with both. I twice now have booted the PC and a faint image of the BIOS screen very quickly expands on the screen and fades out unil its black again. Ive also seen the OSD do the same thing once (I think also during boot).
I'm just not sure what's going wrong. At first I thought it was a resolution issue on my PC's side, since both the seller and an online source listed it as 1800x1440x76hz (I assume the seller got their info from there), but the manual says its max resolution is 1600x1200x85. Ive tried pugging it into my motherboard's VGA port, an old discrete GPU's VGA, a DisplayPort to VGA adapter and an active (tested and working) DVI-D to VGA adapter adn the VGA port built into an older laptop. All of it behaved the same.
Windows 10 correctly identifies and name of the monitor, and I can change the resolution and refresh rate, but the screen reamins black.
I would really appreciate some help. Thank you!
