Hi,
I have same no display but blinking blue power button light prob.I opened the 740n and seen these three 820mf/25v capacitors and they are definatly blown as I can clearly see that the top of all of em is not straight which is symptom of blown capacitor.I am not sure about the fuse All I see is one fuse just behind 220v power pin connector,a round brown fuse.
All I am confused is that what caused all this as if I even change the capacitors it might again blow the capacitors as there might be some other part malfunctioning.
Can anyone put some light on it as if there are any other solutions. saadsatti@hotmail.com
Thanks

Samsung syncmaster 2220 blinking blue light and no image display


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

Reset button hp pavilion


Hi,
HP Pavilion not available reset button.
A hard or forced reset erases all information in the computer's memory which may restore functionality. Resetting your computer forces the system to clear and reestablish the software connections between the BIOS and the hardware.

Performing a hard or forced reset might fix the following conditions:-
Windows stops responding.
Computer stops before Windows loads - no boot, blinking cursor on a black display, and errors relating to OS not found or a missing drive.
Display suddenly goes blank and stays blank.
Software freezes.
Keyboard stops responding.
The computer does not return from sleep or suspend mode.

Thanks..

Damn Blinking!


You can buy a used monitor about $50.00 in the US. or You should take the monitor to an authorized repairman. IT IS NOT recommended to fiddle by banging a defective unit WHICH has HIGH voltage running through it.

firstly stop turning it off and on because you will blow something else like a power board then it will be a big paper weight.
next get a torch and when it is powered on and supposed to be showing images, shine the torch at the screen.
if you can see everything then you have a broken backlight or problem with your backlight and connections.
they cost approx £15 and a little labour, its not a big job. you may be able to do it yourself if you can get hold of a service manual.

Display problems please help


This seems to be a problem of the Invertor or powersupply board.If you are technically able check the boards visually,look for bulging discoloured capacitors. Try replacing these components it may solve your problem.
