Device will not power on after usb c replacement

Orange jouce was spilled on my MacBook pro M3. After a few days the usb c started to not work. I removed the back cover revealing some corrosion on the main board. (Device was working just fine other than usb c). I removed the main board, cleaned with rubbing alcohol and a new toothbrush. It cleaned up really well. I let dry for 18 hours and re assembeled everything. Now it will not power on unfortunately.

I tried charging it, no light or any sign of life. Holding the power button while plugged in.

I even took the back off and re connected the battery and screen. Still nothing.

Please help! I have no apple store in my country and need to fix this!

Thanks

Good to state exactly where the juice was spilled on the keyboard / logic board and the country you are located in, It is likely there will be a shorted circuit and some board level surgery required & or a defective keyboard power button if the spill was on that location.

Juice was spilled on the side of the laptop. By the mag safe and 2 usb c ports. None got on the top of the machine

Over the years Apple has moved to smaller and smaller discrete components as such using a toothbrush might be a bit too aggressive, pulling or damaging one or two. Orange Juice is both quite surgery and acidic, so if leaf on the logic board too long it can cause damage.

You stated it was still working before you took it apart so that leads me to believe the logic board was already in a fragile state.

Can you give us a clue where you live, country and nearest major city maybe we can aim you to someone who can help you.

@danj You need to read your answers before posting as there are always mistakes which may make the answer make no sense at all (Orange Juice is both quite surgery).& so if leaf on the logic board ... You stated it was still working before you took it apart so that leads me to believe the logic board was already in a fragile state. ???
