Hi There,

I have a pioneer cdj 400 that took a knock and now will not power on, there is no physical damage as far as i can tell, im guessing it could be a broken solder joint or somthing similar causing the problem.

does anyone on here have experience with these players??
could anyone point me in the right direction to start testing?

when the power is switched on the cd drive activates and i can insert and eject a disc, (the eject button on the pcb is working) i can also plug into a pc and the sound card is recognised and installed.

It would seem the issue is with the LCD and the LED, buttons appear to be working? one crucial connection that powers these broken maybe?

any help appreciated!

Thanks
Dazzler
