Desktop Screen Display

HP Recommended

Hello, I have an old HP desktop. The tower has no problem powering up but the monitor, however, lights up then shows a "no signal" message before shutting off. The display is black but the yellow power light is still on. Please HELP!

I understand that you are getting no signal while connected to the monitor.


Have you tried to replace the display cable?
