Does the chip need to be 4562 L72A?
My chip has 4562 L62S?

Try reflowing these 4 tiny holes on the back of that board. I would not add extra solder unless you cover the nearby holes with something like kapton tape to prevent bridging. The inner 2 of the 4 are the 5v (red circles) and the outer 2 (black circles) along with the 4 big ones are ground https://...

Reverse the cables when you do the continuity testing for a true test. The LED comes on because the multimeter is essentially powering it. R2 on the power board looks bridged to me also. Clear that and try moving the wire (between the LED and U1 chip) up from the pins a little and see what happens....

When you plug in the USB it should light up the LED and I test every single board before I ship it since I was hand repairing them. So this tell me that you have a bad cable maybe? or something is shorting to GND. Remove the battery and see if the LED lights up and FB3 will not have any power if th...

I unable to get my minty V3 to power up using the power board. Everything works find if power applied directly to raspberry pi. I did the continuity check on the controller and power pcbs and they all check out fine except battery + to FB3. Is the power board led suppose to turn on when plugged in? ...
