Behringer ub1622fx-pro power supply problem

[Fractured Logic]

Can anyone point me in the right direction to fix a faulty power supply
on a behringer up1622fx mixer. The symptoms are a phantom power led
that lights up but the main console has no power.

I have read that it might be one of the secondary rectifiers (possibly
d6). Has anyone had any luck with this?

Any help would be appreciated.

Cheers,

Rob

Is that one of the Behringers which uses a cheesy little DIN connector for
the p.s. connections? IME, the plastic locating tab gets broken off on
those, and the p.s. gets plugged in wrong, bending over and shorting out
pins. Examine the male connector carefully with a magnifying glass and go
from there.

Hello Rob. I should start by saying that this repair is not to be
undertaken by someone other than a trained and qualified electronics
repair technician. I cannot make that determination via the internet,
so I must recommend that you bring the unit to one of our authorized
service centers. In addition to the safety issues associated with AC
mains electrical power, is also true that opening the unit will exclude
you from warranty coverage. If you are not a trained tech, or if your
unit is still under the original warranty, just drop me an email at my
address below and I'll be glad to help you find the nearest BEHRINGER
authorized service center.

If you know that you are qualified to perform such repairs, and the
warranty coverage is not an issue, I would suggest you check D6 and D8.
If either one has failed I recommend replacing them both. If you test
and verify that both are good, the TOP245Y switching IC would be the
other possibility (remote).

I saw another response asking what type of power supply this is. This
is an internal switching PSU with AC mains coming in from an IEC
connector. It is not an external DC supply (wall wart).

Let me know if you need help locating an authorized repair center in
your area.

Thanks for your quick response. I tested and determined that d8 was
bad. I have read that replacing the her303 with a her508 was advisable.
I would normally replace with like parts, however, it was suggested
that the her508 was better suited for the application. From your
experience would this be an issue?

Cheers,

Rob
