Why is my Monitor blank when i switch on the pc?

If the computer is attached properly and you get the flashing lights it is due to switch mode power supply being faulty, too expensive to fix I think you will find, never seems to be anything like just a fuse I'm afraid, modern worlds tells you its time for you next monitor..... do try to ensure it aint the pc by hooking laptop or something else to this unit, or hooking another monitor to your pc to be sure but I find power supply failure is normally how monitors leave this world...

please apply fresh solder from your CRT socket board.

you dont have problem with your monitor, check your cpu very well am very sure you have problems with your system board

The monitor requires service The monitor is not receiving a signal from the computer

Make sure you set up your laptop to display to a second screen. Depending on your Operating system, go to your display properties and go to the settings tab. Then click on the second monitor and enable it.

Depending on when you bought it. There should be at least a one year warranty. If its still under warranty have dell replace it.

1. Mostly Loose contacts in video section that means CRT Neck board dry points checke it.
2.Pl check VGA Cable RGB signal pins 123 to ground 75 Ohms (on OK condition).
3.check 5v supply
4.check SDL and SCL signals.

It may be the Monitor Problem or Re-Install the vga drivers with the cd you get while buying the motherboard.

If the problem continues re-install the OS witht the latest service packs available

Let me know if your problem is solved and rate me as FIXYA!

The Monitor is bad, with the CRT Monitors you cannot just replace the connections, because it is embedded into the CRT. So it is probably something that lies with in the monitor itself. Try to connect another monitor to the device. See what the result is, my best guest is the CRT Monitor when bad. Time to replace! Sorry!

back light or inverter problem Dont know about repairs though.
