SOURCE: Pioneer DJM-400 mixer turns on, but channels aren't working
could be a few things , what have you tried to trouble shoot the problem ?
My steps would be ;
check all leads (even if you KNOW u pluged them in)
check the gain is set corectly .
check the line phono slectors are set to what ever you have you leads pluged into on the back of the mixer ( there is 4 red and white RCA plugs , 2 for phono,2 for line CDJs shold be using line )
if you are using digital cables to conect your CDJs , on the back on the mixer there is a small switch marked "CD or digital" make sure that is sleceted "digital " . if ur not using digital cables make sure it is on "CD" .
the info iv put here is based on the DJM-800 so your mixer my not have some of these featers as iv never used a 400 . hope this helps dued . check out www.djtutor.com for more tricks and tips . Pratices'N'enjoy !

Does it buzz through cans? (headphones). Try listening on headphones (turn off any amps and speakers) on cue to each channel you use and to the master output. is it stil there? if so it's an all round earthing fault. If it's all good through the cans (sorry...I mean headphones), try it with the amp/s on again. If the buzz is back it souds like the screen on the main audio output connecters has come off inside.
It's a quick fix, but if you have never used a solder iron, take to someone who has.

Since it works with your other mixer, the DJM400 is probably fine. You have a ground loop.
Make sure ALL, and I do mean ALL... (re-read that if there is any confusion) interconnected equipment WILL BE powered from the same receptacle or source. If speakers or amps are powered from one place and the DJM is from the other end of the room you likely have a ground loop and you can ex[ect buzzing. Run extension cords alongside the audio leads if necessaryy to carry power from where the amps or speakers are plugged in back to the DJM400 and ANY pther connected equipment.
SOURCE: what size is the glass
You need to REPAIR the cause of it blowing before you worry about what size it is. Replacing it without repairing MAY damage additional components.
For 220 Volt service it appears to be 250ma for 120 it appears to be 400ma
Here is service manual:
