Pavilion550 will not boot up. Error: check signal cable

[schlampet]

Turned on the computer and got a black screen. Eventually an error scrolled across the monitor "CHECK SIGNAL CABLE". Replaced the cable but that did not help. Thank you.

CHECK SIGNAL CABLE -- the cable between the computer and the monitor might not be tightly connected, or the cable may not be transmitting the signals from the computer.

Or, the monitor is reporting that the computer is not generating any video-output.

This could be a dead motherboard, or a dead video-adapter inside your computer.

Can you connect the monitor to a different computer? Does it work correctly?
