Re: Monitor Desplay Troubleshot

To add to what spawn2000 suggest,i will say you should try adjusting the variable resistor that controls the colours.there is one for red,green.

Hi we have a compaq 7550 screen that when turned on has a red sheen over the whole screen. Any solutions or is it ready to throw away. thanks

You may try messing with the settings on the monitor. The menu buttons are usually on the front. Try to find something that deals with the color tones of the monitor. If messing with these settings doesn't fix your problem, then unfortunately, it is probably time to throw it out.

My speakers on my compaq 7550 have no power. when you turn on the sound, the green light is not lit up, so they are not getting power.

Have you checked the Power supply adaptor and the power cord plugs? If all are okay, then the power supply adaptor is the problem. Change the power supply and it should work.

My crt moniter not desplay color properly

Usually it's not the monitor but the video card when it comes to color configuration. You need to ensure the proper driver is installed on your system for the video card or go to device manager and delete the video card and reboot to have windows find it again.

It could be a simple right-click on the desktop to display properties and change the color as well as resolution.

10 min delay in desplay after cpu starts

Sounds to me like lack of power to the monitor, or a problem with the bulb inside the screen. I would definitely recommend you to replace the screen
