DIY Repair of Onkyo TX-SR875

josha · 10th January 2011, 08:12 PM

Hi All,

I recently picked up a faulty untested Onkyo TX-SR875 for about £80ukp, taking a chance on being able to repair it, however I've come unstuck!

Fired it up and tested all the inputs pre-outs and speaker terminals discovering the fault to be with the left front channel. No output at the terminals (so I thought a problem with the amp section) however - no output on the pre-out either, arghhh.

So - the fault is probably on the main board, either with the two IC's (volume & analogue switch) or with the supporting components (ne5532's & transistors).

The question is....has anyone here attempted a DIY fix on one of these beasts?

Any help / thoughts greatly appreciated!

Josh
