Faulty Wii Remote - Idea's ??

hi all,
I have a wii remote here that just wont power on :/
It's a launch unit..

I checked the fuses and they are fine
Checked all the buttons for continuity = ok
batteries are fine

reflowed all through hole components

will try reflowing the SMD components

the capacitor looks ok



any ideas? :/

 

Do the lights even flash?

 

Maybe it's the batteries

 

Aye aye, cap'n!

On the serious note, it can be broken trace, spilled conductive liquid or bad solder joint. Extremely hard to find, just like when i tried to repair Hi-MD recorder which can be turned on in about 5 out of 100 attempts, ended with resoldering half of the components with leaded solder and now it works but randomly freezes in about every 10 minutes, i guess i'll have to resolder everything and replace all capacitors.

And it can be even worse - burned out components. But it rarely happens, only when user experiments with external power source. I think that wiimote just hit the wall, which happens very often. Reflowing everything is a good idea, but if there's a crack on pcb it won't help, you'll have to find it.
