Marantz NR-1504 No power

Re: Marantz NR-1504 No power

FYI: Denon AVR-X2000 & AVR-E400 use an identical SMPS, PCB layout is different though. The component numbering is the same as with the NR1504's SMPS. It may broaden your search for usefull repair threads a bit.

Re: Marantz NR-1504 No power

Hello,newbie here.
I have a NR1604 with the same issue, no 5,2 VDC to HDMI board.
I've replaced TOP258, diodes D4142, D4143, D4144, D4145 as suggested in the service manual, caps C4152, C4155, 1M resistors R4141, R4142, R4164 (with bigger wattage).
I have on TOP258:
S - V(1) 5,6 VAC
S - X(2) 2,4 VAC
S - C(3) 11,1 VAC
S - D(4) 711 VAC

I'm afraid to have messed up diodes orientation, even if I checked dozens times.
Can somebody can give a hint?
Thanks!

Hi.
So here I am, with the same problem.
Marantz NR1504, the F4140 fuse is blown and the TOP258MG burned (literally) .
1Mohm resistors are ok...
I cant find the TOP258MG so if someone can tell me if i can use the TOP258MN instead?
Are the TOP258MG ordered from aliexress reliable?

Thanks in advance for the info 😊
