I already replaced the LM317T. Before that there was no rail at all. At the time I thought it would be an easy fix  :-DD

I've ordered a (cheapo) hot air station and will -after some practicing- attempt to remove the SMD chips to find what drains the 3.3V rail...

Watch some good youtube videos on how to do this. Plenty of flux and keep moving the nozzle over the pins is what does it for me, but with IC's that have buried ground pads it is more difficult and the IC might not survive.

Yeah, I've been watching some YT videos already. Looks logical. I do have some experience soldering SMD, just not desoldering with hot air. I will practice on some old PCBs before trying the real thing. I don't think there are any ICs on there with ground pads...

I also got some more flux coming - the hot air station has arrived. Will start playing with it this weekend.
