I mistakely pluged 100v japanese retro game console to 220v outlet.
So It seems that glass fuse and varistor have been blew up.
I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
Is there any way to identify varistor type in my sega saturn PSU?
Any reply would be appreciated.
EDIT:
It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage... -
I had my Quadra 840AV (which I recapped and had working) plugged in for some time without using it and randomly decided to turn it on today. Unfortunately it did not turn on. After checking the PSU, I found out I was not getting anything from 12V, only from the 5V rail. After a few minutes, I removed the PSU and plugged it back in the electrical outlet and it suddenly started making a weird sound and soon after smoke started coming out. I quickly unplugged it. I opened it up but on first instance I didn't see anything out of the ordinary really. I later turned it back on and one of the MOVs blew...12-22-2024, 05:07 AM -

Hi all,
I'm working on a MacBook Pro A2338 M1 (2020) with logic board 820-02020.
The machine has a power issue — not powering on, and I'm trying to trace the fault.
While inspecting the board, I found a cluster of components
This area looks damaged or burned — there are about 4–5 components that seem affected
I've attached a close-up photo of the chip and its surrounding area (see... -
Hi everyone
I have a 70mai Dash Cam A510 which failed after about 3 months of being installed in my car, likely due to heat, i got it from aliexpress so no point in trying to return it for warranty (and shipping it back would cost me almost the same as a new one from ali)
The camera would boot loop showing 70mai logo on the screen, sometimes it would boot fine then the live view would freeze or display purple lines
I already took it apart, and found out that the camera boots fine if i unplug the camera module from the main PCB, sometimes "playing" with the connector...
