and if only plugging in laptop to desktop montor works than you will need a replace the power inverter this part powers the screen and you can find one on ebay at a good price good luck with your computer :)

Hello,

Change the power supply and restart your pc. This will happen when the power supply has gone bad. It sends power to low voltage items but not the needed voltage to power the system on.

Good Luck

the monitor circuit might have a faulty components,
usually a busted capacitor needs a replacement

Unplug all the Cables from Compaq Presario 5103 CL and leave the Keyboard, mouse and monitor cable pluged in.

Now make sure the power cable of the monitor should be pluged in and the power cable of the tower should be pluged in.

Now to check if the montor is fine just unplug the video cable only which will show no input signal on the screen. If it shows this signal the monitor is fine. Plug back in the video cable.

If the monitor is going to sleep mode it might be possible that the old computer ( Compaq Presario 5103 CL ) is in stand by mode. hit any key on the keyboard and it should come back .

If it is not in the stand by mode then do one thing. Check the same monitor with the new computer. If it is working. Perfect ..!

Do one thing now ..!

Unplug all the cables from your old system and then press the power button for 30 sec and let it go. Now plug the keyboard, mouse and the monitor try again.
If it works Perfect. If not ..!

Then you need to open the tower and check on the processor FAN is it running..? If its not running you will not get the display as the fan is responsible for the display on the screen. Otherwise...!

Check the Tower possibly the Tower is not getting the power.

Try these steps and let me know If it works

I once fixed this problem by changing the RAM

you can use any make of computer, any monitor and keyboard will work with any tower. emachine is just the make.. good luck

Your flat screen monitor should have the same connections as your older model, a VGA connection.

It sounds like the on board video has failed. I would try installing a video card on the motherboard. Then in the bios at start up, disable the on board video, so it will use the video card instead.

I hope this helps and thanks for using FixYa,

When you try to turn it on do you get lights ? Do you hear any noise like a high pitched noise coming from it ?

Make sure all the connections are secure ( I'm sure you have tried)
Try plugging it into another tower or on a laptop to see if the monitor is fine and the video card is not to blame.

You first take post( power on self test) connect power cord & disconnect signal cable you will see massage no signal check siganl cable then problem will be in cpu this problem may be solved by cleaning dust in cpu if montor shows no display then problem will in monitor open it check o/p of smps if not disolder path of eht if o/p comes then eht is faulty replace it
