Laing DDC 3.1 PWM: pump ... PCB dead?

post #1 of 27
Thread Starter 
Hi all smile.gif,

I bought this pump as broken, so I was not surprise that it was not working.

I am just a list bit surprised, the PCB look good, no burned componed.

When the pump die, does it always end with burned component?
Is is repairable by replacing components?

I have look a lot on internet, but it seems there is no way to buy Mod PCBs with Toshiba driver, does anyone got a source?

Sorry with all my questions smile.gif

You can try to get ahold of BMaverick on the forums here. He should know where to get a pcb for the pump. Or you can check his site just use Google.

all in all it sounds like its more hasle/cost to restore a broken pump than to buy a working one used tongue.gif

how much did you pay for this, OP?

also in what way is it not working, does it simply not respond to being plugged into electricity or is is trying to spin up but can not achieve rotation?

try to edit your posts instead of making new ones when you have somthing new to say please smile.gif Forum ediquette.


this is just a thought but you could try placing the pcb in the oven and baking it. Its a meathod used on various different PCBs when the solder becomes unseated properly. (you can find it used on GPUs and mobos around here)
