Harman Kardon 460 i problem

[Badula]

Hi all!
Problems…. I just recapped a Harman kardon Receiver 460i
And now. It’s kind of dead…. I have no Bias current.
I have checked for cold soldering like 3 times. And no fuses are popping . And it starts and all.. but I can’t get any current to the idle current .. I cannot understand what’s going on…
any help is appreciated

You must be glad you recapped it

You must've observed the correct electrolytic polarity when renewing - rather than dry joints, it must surely be something you've done eh?

If you've got a circuit diagram and / or voltage markings on the PCB....get your meter and start testing around, checking DC voltages. Are they correct? Are they there?......

I’m afraid that I can’t be of any help, but I feel your pain. Hoping you can quickly find the offending part of the circuit & resolve 🙏

I have went threw the polarities like 10 times now… and checked voltage.. but yeah, i have probably done something wrong somwhere
