Numark 5000FX power

I think you have been lucky! Many manufacturers do not want you to do your own servicing or updating, and guard their Technical stuff jealously. Letting anyone use it opens it up to copycat manufacturing.

Or an earth problem (connecting cable problem) or dirth in potentiometers or some leaking or bad capacitors

For all kind of brands cd or dvd players There is in every cd or dvd tray in the front bottom or under the tray so crazy you can not think an microswitch necessary that will be by mechanic close of the tray detect if the tray is closed and give a timed signal (close or open) to focus laser for reading of table of contents if the belt is bad it can take to long by a slipping tray drivebelt for the detection , or the microswitch or brass plate contacts are have a little corrosion on it or even it can be broken by a missing timing.

The signal path to follow is explained below:

*Audio Source(Cd/LapTop/Ipod)output to,
*Numark 5000FX Input, Then master/main outputs go to,
*Behringer FBQ1502 Inputs, then outputs go to,
*Pro600 Power Amplifier Inputs, then power amp outputs hooked up with a speaker each side.

Hope this helps.

Hi, i wonder if you solved your problem, because i have exactly the same issue with my Numark 5000FX and i cant figure out how to solve it.
I would really appreciate any help.

Here are a couple of steps you can do first before opening up the mixer & I'll word this so that it covers every potential item, (Turntables, CDJ's, Rack Mount CD Players, External Player, PC, Laptop, etc.) Obviously there are a multitude of items that could be the cause of you only receiving your RIGHT MASTER OUT since you didnt specify what item this occurs with if not all. So here's a quick legend for you to follow my references regarding the NUMARK 5000FX Mixer so here we go:
*******************************************************************************
MIC/Line Phono/CD Phono/CD Phono/CD LA/LB Zone/Booth/Rec/MSTR
LO LO LO LO LO LO LO LO LO LO LOLOLO LO
RO RO RO RO RO RO RO RO RO RO RORORORO
********************************************************************************
1. Turntables - A) If being used make sure the little black switch on the back is set to Phono instead of CD. Plug just one table in, play the record & see if there's only one side of your MASTER output jumping and make note of it. Then repeat the exact same steps for all Phono inputs (total 3) & again make note of your MASTER output signal Left or Right or Both sides jumping. This will help you identify if its just a specific channell that only works on R or L.
B) Now do the exact steps above for the other turntable & this will confirm whether or not the Phono cables went bad on the turntable or if a specific channell is has gone bad while in Phono mode.
2. CDJ's/Rack Mount CD Player - A) Now just use your CDJ's/Rack Mount CD PLayer for the next test & be sure to now change the little black switch on the back from Phono to CD. Just as the steps with the turntable perform the same for this item in all possible RCA's (total 6) & note your MASTER channell output signals L & R.
B) Now do the same for the other CDJ/Rack Mount CD Player & this will confirm whether or not the RCA cables went bad on the CDJ's/Rack Mount Player or if a specific channell has gone bad while in CD mode.
3. Audio Cables OUT - A) There are a host of ways to have your audio come OUT & multiple configurations depending on how you record &/or bounce your audio OUT. Now since you say your MASTER OUT digital meter is only jumping on the R side depending on if you're going with RCA MASTER OUT or XLR BALANCED MASTER OUT either or is what'll show the digital reader bouncing with audio so check both. It could very well have been a cable going bad on you simple as that & you can check that by pluging your cable that works on the R side into the L side. If it starts showing a reading on the digital meter than you've solved the problem being a bad cable. Also don't forget to check your ZONE, BOOTH & RECORD OUTS as well however these will not show on your digital meter so open up your audio recording software to confirm that L & R sides are working for these.
B) Last but not least double check that your BALANCE knob is set directly at 12 o'clock, this could sometimes be the culpret.

Well I hope this helps & good luck.

There is not an internal fuse.

Or even a cheap replacement laptop power supply as these usually start at 1000 mA which will give you current to spare and have a longer lifetime. most of these cover from 15V to 24V and are either auto switching or manual select for the voltage. Plus you can pick these up from most electronic / big box / supermarket shelves

i'm having the same problem, just wondeered if you found any solutions to this?
