Help for mixing console BEHRINGER UB2442FX-pro

[Jose Manuel Borges]

Friends i have a BEHRINGER mixing console EURORACK UB2442FX-PRO, which is a number of problems, I have no great esperiência in the repair of such devices,
1º only has signal input on channel 1 and channel 4, the other gives nothing.
2º in the signal input to the tape, just enter signal on the right channel.
3º only has signal output on the right.
I would appreciate someone can help me on this repair.

Hi,
I've just been repairing a similar model to this.
You will probably find the amplifier chips on the input board have failed and this could be due to the PSU having bad caps!
These chips are all SMD so if you have no experience I wouldn't even think about having a go at it.
Firstly though, before you get any chips changed make sure the PSU is checked out as it's more than likely that several of the caps have vented and lost their capacitance.

Clean ALL switches (push buttons) for starters. Most of the dead channels will come back to life. You'll have to do this anyway. Then you can check the rest of the mixer like the sliders, opamps etc.
