Need help diagnosing a "No Signal Detected" error

[William]

Hi All,

My Cobra has been sitting idle for sometime. Yesterday I went to fire it up again. On the console, I turned the switch to ON. The monitor fired up, after a few seconds it switched to an error message "No Signal Detected", and then the monitor shut down (went black). The router however did fire up which leads me to believe it's a computer issue but unfortunately, I have no idea how to start diagnosing this. Any suggestions?

Thanks,
William

first thing I'd do. Try disconnect reconnect the cables from machine to computer and computer to monitor. Make sure they are all plugged in well.

The pc will work with the machine unplugged from it, so start there and get the pc running. Sometimes pulling and re-installing ram will work.

Thanks Eddie and Ken. I contacted support and they thought it was something called the CMOS battery. They gave me a manual way to start the PC but it didn't work. All the cables seemed to be properly connected. I'm going to see what they say before I start disassembling it further.

Check cables to monitor, thats usually the issue.

turn on the monitor then turn on the computer. You should get the windows start up screen if not the it is either that cable or bad video card
