Hi this is a really odd case.
I have removed all of the esd ic for USB 3.0 and 2.0
I measured all of the data lines and 5v usb voltage lines there are no shorts
all of the USB ports have no damage
Clearing the bios using the jumper wont help.
it is still showing USB overcurrent device
the only temporary fix I've tried and worked so far is flashing the bios
and the error is gone
but when you start the motherboard with a USB device still attached
the USB over current device error is back. the bios needs to be externally flashed... -
Hi all,
Wanted to share this as I couldn't find anything on the internet about this problem, so pulled one apart and found the problem myself. Years ago I bought approx 20 or so Crest Smart Home Single Power Adapter smart switches - small 240v Tuya-compatible (rebranded) smart switch devices with power monitoring, which Big W had on sale for half price. Paid $7.50 each for these, and they've been incredibly useful for turning things on and off remotely... and monitoring how much power each device uses.
However, after about 12 months, I had a number of these stop working... -

Hey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:
The schematic...
