monitor power button broken, any ways of turning it on

[ssjgokou1]

My button on my monitor (which pops out when you press it, not like those that you can press, and they stay in until you press them to pop out) has been jammed or something, so I took the button part of the monitor apart, and found that it's a little disk that touches the outer part of the curcuit board, but when it gets pressed in, the outside, and inside of the curcuit board gets touched by the button, and hence there is a connection, so all I had to do was to get the disk to flip back to the curved shape, but now I can't get the button back together, all I see are two rings, one ring which is touched by the outside of the disk, and the inner ring, which gets touched by the inside of the button when you press it, so as I figure it, I need to get a piece of metal to touch both rings, so I can make them establish a contact. Can anyone help me, or tell me what to do?

Glue the button carefully back in place. Them RMA it.

If that doesn't work then sell the whole rigmarole in the AnandTech For Sale/Trade Forum.

RMA?!?!?! Who will buy it if it doesn't work?

Okay I followed you completely until you got to the "disk to flip back to the curved shape" part....I understand how these switches work but it seems the problem is in the mechanism of the plastic switch?...correct?
Is the disk a metallic spring steel? These make momentary contact and then they flex back to normal which breaks the contact...Is this okay?

yes! thats it, I got a curved shaped disk, which pops in, and then pops out from the center when you let the button go, this was stuck, and all I had to do was to get the disk to pop out, and now it did, but I can't get it back in. Maybe it wasn't the disk but the curcuit that was behind it, you said that you know how these switches work, can you speculate a wee bit on it? Any help is always appreciated,

Thanks!

ohh, I have a good way to explain the disk, you know those snapple, cans that have the "do not buy if button is popped" out thing? Like that, where you can press it in the middle and it makes a popping sound The curcuit that it lays on would be a big circle on the outside (where the outter part of the disk touches/lays on) and a smaller circle that's inside the bigger circle which isn't being touched unless you press the button to make it go inwards, then the outside of the cirle touches the inside of the circle via the disk.

Okay it's as I thought, this disc which is a momentary switch acts like a spring, push it and it makes momentary contact with the two traces on the circuit board completing the circuit, and it issupposed to pop out by itself.
Well it doesn't anymore. The metal has weakened with time and no longer pops out.

Now to fix it....(I assume it's not under warranty?)

You could phone around local monitor or possibly television repair shops and tell them the exact model and that you need a replacement power switch and let a bunch of them hunt one down for you and get some prices.Then pickup the cheapest and install it yourself.
For now you can make momentary contact with a small screwdriver to the two contacts to get it running and just leave it on 24/7 until you can find the part.

That's what I was thinking, but about getting a replacement button, I don't think that will happen because I got my button integrated on the board, so there is no way to replace the button (it's not like my computers button which plugs itself into the mobo, which can be easily replaced) Do you think that the contacts go bad after a while, that may have been the problem, I don't think that a stupid disk can go bad ever, unless you bend it so much to the other end, that it will no bend back.

Here is a good idea, since my monitor has sleep mode, when my computer is turned off, the monitor will be in safe mode, and taking up minimal energy, so I could leave it on forever, even if the power goes out, when it comes back, the monitor will turn back on again and again because unless I take a screw driver again and make the contacts touch again to turn it off, which I don't plan on doing.

That is what I think has happened, the metal has weakened and like you mentioned doesn't pop out like it should. There is likely nothing wrong with the contacts besides possibly being dirty.
If the switch is soldered onto the PCB you can still get a shop to order you one and solder it yourself or get some estimates for a shop to do it. (shouldn't cost too much, only two legs to solder)

Like I mentioned, leaving it on 24/7 is the best plan right now, I leave my monitors on 24/7 also and just let them sleep after 20 minutes, it's better for them than turning it off and on anyway.

It was late at night here. I was just making a JOKE !!!

I'm sorry !!!

Seriously I'm glad you got your problem solved.
