I have two keyboards, one is an old re-branded Casio, the other is a Yamaha PSR E403. The casio won't power up unless I jiggle the power cord around, and on the yamaha I have to hold it upwards just to get it to power on. If I hold the wire in place, they will stay on and work as normal. The plugs seem to be in working order too. What is it that is causing this, and what can I do about it?

I get the feeling It'll be something I'm not looking forward to :S

Have somebody open them up and resolder the jacks to the circuit boards.

I just took out about 30 odd screws from the keyboard, to find one solder joint cracked on the power jack, in the most awkward place EVAR Evil or Very Mad

I didn't have any solder so I made do with what was already on the board...
Needless to say it looks burnt and awful...

But SHE WORKS!!!

I don't think it'll hold for too long, but when it eventually breaks again I'll probably be motivated to buy some decent solder Razz

Cheers for confirming what I thought, it gave me the balls to open it up and give it a try. I'll ignore the casio one as it still works when I jiggle the cord and then don't touch it Razz

Once again, thanks Very Happy

If it's burnt that bad use a jumper wire.

You could use a wire by melting the solder on the jack and the board and then sticking the wire in between, but it's already been dealt with, I ain't trying that again anytime soon -_-

My microwave thread has had less fortune however as the best advice I can get is BE AFRAID OF DEATH and stick a fork in it. Do you how I could get better advice? I've put down all the details I felt were necessary for someone experienced to understand what is wrong with the thing.
As for experience, that comes from insight and hands-on work, and I need some older dude for the insight Razz

Without some guidance from people who know what they're doing, I may as well be trying to build a zoo based on a book about how to raise penguins.
