Re: Onkyo tx-nr414 shutting off after few seconds
There is -0.5v output offset on one channel only (SL) going to speaker relay out - that is for sure too much, and by mine opinion would trigger protection as it is connected directly to vprotect line...
-0.5v is at P6083, NPLG-2P29 (page 9 (2IJ location on this page)) or in short NFSL line to ground.
60v is because mine mains voltage *is at 250vac, as I have already mentioned at this thread but would not consider it significant.
Now that you mentioned it again I have double checked that by lowering mains to 230vac as specified and for sure output on my 60v line drops to nr414 regular 56.2 volts.
They maybe should not wrote that voltage fixed in service manual not to confuse service personnel, 52-60v should be written and that would make it easier.
