All,
The powerbutton on my 17" color MegaPixel N4001 is acting a bit flakey. It no longer stays depressed in the on position, so I have to manually hold it (i.e. jam in a strip of paper) to keep my monitor from turning off.
I managed to remove the power button by doing a bit of exploratory surgery, but failed to see anything mechanically wrong with the switch. I did not take the switch apart. At this point, I'm assuming that something inside the switch such as a hook or catch is broken.
Has anyone had this problem before? I'm thinking at this point I need to replace the power button. Does anyone know what part I need to look for? I did not remove the metal cage due to concerns about high voltage. Are the wires connecting the power button safe to work on? If not, is there a safe way to degauss the monitor so I can work on it?
Thanks,
Brian Moore
I have the same problem on one of mine. I haven't done anything about it yet, but if you do, be sure to let us know what you find out!
Typically monitors and other appliances will switch on/off the low voltage side of the supply. The monitor (tube) will have a step-up power supply so the 120v side will be where your power switch is.
If you can find a part# or manufacturer on the switch, you might try to do a google search. If you have enough information, I would try Mouser Electronics for replacement parts. Generally speaking, they have a great selection of stuff and you might be able to find a replacement part there.
