Stuck on a board repair
Hello guys, I'm trying to repair this board and have found the problem but am struggling with the cause and solution.
Image link doesn't seem to of worked but you can view them here: https://imgur.com/a/x7CbgLw
So, from what I have worked out, 12V input goes to the STM32100 circled in red. This chip is receiving power on all points and the only problem with this board is caused by 1 output on that chip, so I'm guessing it's not the chip.
The output signal from the pin (PA6) on the Stm chip then goes to the input of the next chip D5160J circled in yellow. This input pin is the switch for the output side, so one it receives a signal from the STM it will send the output voltage to the 4 pin connector above it.
It's not sending any signal though for some reason, im not sure if the STM chip is supposed to receive something on one of its inputs to then output its signal on PA6 so I'm stuck.
Does anyone have any advice please? What do I do next? What would you do here?
