Sorry, but I never worked or own anything Bose. Not a fan. If by any chance you find shorted final transistors at a channel, don't just replace those and turn it on, because may blow it again. Usually there are more parts blown, most likely on the vertical pre-amp board. Usually I test all the component, before and after the repair, to be sure that I did not miss anything. You can compare measurements with an adjacent channel.

You could try a reset(not what is in the manual, one that it should be in the service manual), but if that doesn't work, you may have a blown amp channel. I'm not familiar with this new generation of receivers. Personally I would take the cover off, and with a meter I would check all the final transistors on the big heatsink for short.

I agree.

They probably only replace the board, which is way to much most likely. Not worth it. For a few years it was a "recall", and they fixed it for free, but that is long gone.

On newer Onkyos, the caps are not a problem anymore.

You need to find a newer model IC, which is DxxxxxxxxxD400. The second D has to be D, not B. You can find them only on newer Onkyo HDMI boards. The ones on Ali are fake.

Maybe more bad capacitors?

Manufacturer won't sell these to customers/stores, only to manufacturers, like Onkyo, Pioneer, etc. Your only safe bet is buying a broken board and harvest the chip from it.

I have got an X7 with the same error light code. Found on the ballast board's daughter board, that the LNK363 IC was delivering only 14 ish volts, instead of 17V. That caused the 5V LDO to supply only 3.6-4.2V and that wasn't enough. Replaced the LNK363 and pj started right up.

I have a TX-RZ810 receiver, that has a badly cracked base amp board. I'm wondering if anybody knows, another receiver that has the same board that could be used in this receiver. I believe that the 5 series(656/757) may have the same board?!

Most likely it is to old that device.

Do you hear two clicks from relays when you turn it on?

Aliexpress onse are fakes. Try to find a broken HDMI board from a newer Onkyo model, and use that IC.

DSP chip is bad?! B series should be replaced with D series. D830K013(B)ZKB4
