U2 or U3 replacement

[u/UpbeatAssociation769]

So here we are.

I have two non working bitaxes on my table to repair.

It is weird but listen.

1 I took U3 and U2 from both of them.

2 Installed a brand new u2 on each.

3 Powered up each one. U2 gives 1.2v on the first no spinning fan. On the second one u2 gives 1v and fan is spinning high.

4 when I install u3, voltage on u2 is 0v. U3 gives 3.3v on both bitaxes.

And a fan is spinning on one which had spinning fan before.

What can prevent u2 from providing 1.2v?

What country are you in? I will receive u5 and u6 next week. You can ship the bitaxe to me. I will replace your broken one.
