Hello, I have 2 old chargers for Sony DV, and I found the same resistor fuse dead. Fuse is a crossing component : 0,47 Ohms (0,125W deduced because the lenght is 3mm). But I can’t find the same for buy.
So, I want to replace by another like 0 Ohms, 1 Ohms 0,125W,
It is the same please ? I guess it’s the same, the only change should be the time to burn ? Thanks... -

I put it in DFU and it didn't do anything, wasn't detected on other machine.
Voltages all seem OK near the CD3217 chips, all LDOs are present, also no liquid damage was nowhere around those.
