Blue Monitor Blues

I have a Sony Trinitron Monitor and a Compaq Pentium 233 and
I was trying to plug in a phone line into the modem when the Monitor disconnected, I plugged it back into the connection and the Monitor turned blue. I have since uninstalled the graphics card from the device manager and reinstalled it and the drivers, still blue. I used the onscreen monitor buttons to take out blue add red etc. still blue. Will I stay blue until I get a new Monitor...is the Monitor blown , I have heard never plug anything in while the computer is on but have never run into a problem until now, I fear I blew it. (out)!

 

have you disconnected the monitor & then went to device manager & removed it there. Then reboot w/ a freshly plugged in monitor & let plug & play find it....then check for updated drivers.
also see if there are new drivers for it that need to be downloaded.

also you need to reset the refresh rate to default in display properties.

 

When the monitor displays one color far more prominently than others or does not display one or more colors at all, it indicates either a problem with a loose connection between the monitor and the video card or a bent pin on the monitor cable or a hardware failure inside the monitor (which is too expensive to repair).

Shut down the computer. Unplug the monitor cable from the back of the computer. Look at the pins on the cable. Do any of them look bent? If not, firmly reconnect the cable to the video card, and turn on the computer. If the display is still blue, the monitor is shot. It's a mere coincidence that the monitor failed right after you plugged a phone line into the computer.
