My Yamaha amp RX-V671 has decided it no longer wishes to operate :/
I think we had a power surge/outage a couple of days ago as my PS4 informed me that I hadn't turned it off properly, it's usually left in rest mode to charge the pads, anyway, amp turned itself off when my wife turned it on, and then again, so I tried, same thing, I reset the amp, checked all speaker cables
then powered it back on, success, it worked fine for about 45 mins then switched off again, now it will not stay on.
Diagnostic mode gives the error: PS: PRT 135 H (the 135 value fluctuates from 130-145/ I have reset the amp 2-3 times)
I also see a fluctuating value in p1-2 diagnostic: PS 160/129 which suggests a high volt error somewhere, 1.6v instead of 1.3v ?
Been volt testing this unit today, Ac/Dc board for the 5v, turned amp off then knocked the on button and amp turned on but this time it stayed on, 🗣🗣
Still no red led so there is still an issue somewhere
Any ideas please ? TIA
