Thanks, so I am getting it even without the main L/R digital outs. That is good news for me, at least I can use the G68D as connection between a TV optical output and the speakers. The problem with the Zone outputs is that it didn't offer any kind of speaker adjustments, but it's better than nothing.

That is what I have thought.

Thanks, Ron.
In the weekend I will disassemble the unit, check for visual failures and clean everything. Apart from the non digital audio output, the units performs normally. One thing that I might had forgot to mention is that this unit is the D version, so there is only digital outputs except those 2 for subwoofers and the ones for the Zone 2 and Zone 3, but the ones that are for the subs aren't working as well.

Is there a point in the digital output board that I can make some read to see if there is any energy going in to that board? If there is no energy entering the board, my problem could be before it, if there is power entering, the problem could be before and after the digital out board.

About the PSU, I already so the technical explanation on Duncan's page, it seems a pretty easy change and also not an expensive one.

Did you install the XP POWER ECM60UT31 as your new PSU?

Cheers,
Jorge
