I've been using a Turnigy Accucell6 as my primary charger for quite some time now, and it's great. The only thing I don't like about it is that for whatever reason, the >/+ and Start/Enter buttons have 'died'. They didn't click like how they used to, and the Start/Enter button in particular required a lot of force for it to register a push. You can imagine how frustrating it is when trying to initiate a charge, only to realize after ten seconds or so you've been pushing hard for no reason.

Here's the charger pre-breakdown

Removing the shell, apparently the buttons are really tall ones with a cap on it

I realized that I never took off the screen protection plastic, better late than never

Underneath, the two mosfets were sort of heatsinked to the bottom of the case

Peeling off the thermal pad

I removed the old switches using my reflow blower, and unfortunately I knocked off a smt resistor.

I guessed that it was also a 1002 like its cousins on the other switches, so I soldered a 10k normal resistor to the pads. Thankfully there was enough room for it

Soldering them to the pcb. I found out that only the top half is used, since the original switches are SPDT.

Plugged in, nothing exploded so I think it's okay

One last close look before it goes back together

Buttons work satisfactorily again, not to mention the screen looks better without the plastic covering it.

I'm genuinely surprised that the old stock project SPST pushbuttons I grew used to using about 12 years ago still work, and even more surprising that it looks almost factory. Too bad the button caps weren't black. :D
