When I opened it up, the fuse was blown and it was blown the same way as the OP's VCR's fuse was blown, which was pitch black glass like it had blown really hard from some sort of hard surge of some sort.
I had attempted to check capacitors and transistors on the power supply board and I only saw one capacitor that looked bulged and I replaced it and the VCR didn't come back to life, it still was blowing fuses.  |
You can follow along with me as I attempt to repair mine, we might solve it together
So far, I can say Q4 is definitely one of the issues. Still need to check diodes and capacitors
I pulled C5 which is a 120uf 200V cap, and tested with my DMM.. in capacitance mode it read 125uf which is fine, in resistance mode I got 18MOhms, when hooked up to 9v battery and measured I was getting 9V so i think this one is okay.
None of the caps looked bulged so I can either test 1 by 1 or replace them all as a precaution
