I recently found an old Samsung monitor, the SyncMaster 730B, while thrifting. When I plug it in, it turns on but displays a message saying "Check Signal Cable." I opened it up to see if I could find any issues, but didn't notice anything wrong. I did see two connection points—one is blue and the other white, both with several holes. Any advice on how to fix this issue? Feel free to ask if you need more info!

Make sure your computer's display cable is connected to the video card if you have one. Sometimes it's easy to overlook which port to use, especially with older machines. If you're using an All-in-One, check if it's stuck in monitor mode—look for buttons or lights underneath the screen; you might need to switch back to the internal display.
It sounds like the monitor isn't receiving a video signal from your computer. First, try unplugging your video cable and then turning on the monitor. If you still get the same "Check Signal Cable" message, it's a good indicator that the monitor is having trouble getting a signal. If possible, try using a different video cable to see if that helps. Also, if your PC has a dedicated video card, make sure you're connecting the video cable to that instead of the integrated video port.
You've got a classic setup here! The blue connection is typically for analog (VGA) and the white one is for DVI, which is better if your PC supports it. Just plug in the appropriate video cable from your computer to the monitor, and don't forget to select the correct input on the monitor itself. Keep in mind, both of these connections are pretty outdated!
