You can try to replace the capacitor C845 on the power board, 470uf 25V. You'll know if it's bad if the top of the cap is 'bulging'. It may also be seeping a paste or liquid (the dielectric)

Radioshack sells a 470uf, 35V cap for $1.37 and it will work fine.

Try unplugging it from the wall outlet for awhile to re-set it.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can


I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

Please post back in a Comment.

My monitor turns on with a green light and then immediately changes to a yellow light


Sounds like you have no video output from the motherboard. Unplug your desktop computer from the wall so no power is going thru it. Take out all the memory sticks from the slots. Then go ahead and reseat one of them in any slot. Then with the Monitor hooked up turn on the computer. If you still don't get video then repeat the steps and try the memory in each other slot.
If you have more then one memory stick try each one in each slot. If you still have no video after trying all the slots with each different memory stick then that means the motherboard is bad.
If you have a external video card that was installed then take that out and use the internal one that your motherboard came with and swap out the memory using that.
Basically your turning off the computer swapping memory out in each slot and turning the computer back on to see if you get video to come back on.

Monitor is switching off immediately after system is switched on. Again when monitor is switched on, images appear for about 3 seconds and again monitor switches off.pl give the solution.


You need to determine if you is turning off or going into standby mode. When your monitor shuts off, the power light will turn orange if it is in standby or the light will turn completely off if the monitor turns off. If your monitor goes to standby, that means that your monitor is losing signal which indicates a problem with your PC. #1 Make sure cable is firmly secured and both screws are tight #2 Check your video card make sure that it is firmly in its slot. Take it out and put it back in. *as long as your computer is open give it a good cleaning with compressed air* If those things check out it is possible that your video card has failed and needs to be replaced.
If your monitor is powering off #1Check plugins- try something else (i.e. lamp) in the outlet #2 Try your PC's power cord in your monitor

My tower has power but won't come on


first guess is the motherboard is bad

a few things you can try:

unhook the monitor from the computer and test it on another computer. If the monitor works then its most likely the motherboard.

leave the computer unplugged for a few hours then plug it back up and give it another try just in case it overheated.

have the computers power supply tested as a bad power supply can cause all sorts of issues.

other than that you are down to a new motherboard and or a new computer.

I have a shap lcd computer monitor and when i plug it into my computer and turn the power on, the little green power light comes on, screens back. and after 5-10 seconds the light turns orange and blinks...


It could be your monitor is fine. It simply goes to a cycle when its turned on and does not detect any signal coming from your CPU, it simply goes on standby mode (hence the darker image and orange/blinking light.) have you checked the computer (CPU) part?

My nec 1760v monitor goes into sleep mode while i am using it and the only way to get it out is to turn it off and then on.


In Windows, right click any empty space on the desktop> Properties >Screensaver>Power

Check settings \to TURN OFF your monitor in some time.. see if setting this OFF works.
