I have bought new SSD and installed it in my PC. Before that I removed fstab entries for old hard drives, then removed their power and SATA cables. Now manjaro doesn’t boot
Your avatar name inspired me to ask this:
are you sure you did not remove or comment out the line referring to your system / (root) ?
No, it is in place. I remembered that I had symlinks leading to hard drives in my home directory and removed them with installation medium. That didn’t help
No one can help you if you don’t share cold hard facts.
inxi -Fazy (for instance)
lsblk -f
and the contents of the current /etc/fstab
as well as what your kernel command line looks like
(in /etc/default/grub )
Perhaps you could expand on this. At what point does it fail to boot? Are there any error messages? If so, what are they? Does it reach GRUB and then fail? Does it reach Plymouth (the three dots) and then fail? Does it reach the Login screen and then fail?
I think you get the picture - more information is needed. Logs would be ideal, if you can boot far enough to use a TTY shell. Otherwise, if you boot with a Manjaro Live Installer, you could attempt to enter a chroot environment manjaro-chroot -a and generate logs that way, plus other outputs that will help other members to identify the problem.
Cheers.

UEFI screen appears, then it goes black and unresponsive
I just skimmed your outputs posted. Knowing that you’re using BTRFS would have also helped earlier. I don’t use it, and only have a basic knowledge of BTRFS, so my help will be limited.
Which ‘UEFI screen’ do you mean? Sometimes a BIOS firmware can splash a screen very early during boot; is that what you mean? That would mean it doesn’t reach the GRUB menu at all.
I mean the splash screen from motherboard itself. Manjaro loading screen doesn’t appear as it should. GRUB menu doesn’t appear on my system normally (probably cause it’s set to auto in config). Maybe I should chroot and edit grub config so that it appears always or beeps when it’s reached?
If it’s not getting that far it likely won’t do much yet.
I’m presuming you can boot into BIOS. Do so, ad see if you can re-select the entry that dhould be first in boot order - possibly ‘UEFI OS’ or similar - then save and exit; i should reboot automatically.
While you’re in BIOS note down whatever entires are available (just for reference).
If that does nothing, chroot might be your only option; and here, unfortunately is where I’ll need to make way for someone with specific BTRFS knowledge.
Sorry, I should have written about that before. I tried that right away when problem appeared. List featured currently plugged in disks and a UEFI OS which is Manjaro. It’s first in order and trying to boot from it manually doesn’t change anything
Have you done anything that might have changed a UUID?
In your /etc/default/grub Grub command line I don’t see any reference to your system root - just to the swap for resume.
But I really do not know my way around BTRFS and am sorry to have to tell you that I cannot be of any help here.
Not saying that there is anything wrong, just that I really don’t know.
No, and my configs seem fine in that regard
This might be one of those occasions where Manjaro’s install-grub might be useful. What’s your take on that?
Check efibootmgr to show a list of boot.
Try to run
grub-install --efi-directory=/boot/efi
then
grub-update
I have no take on it - I’m totally ignorant when it comes to BTRFS.
I’m also hesitant to suggest anything here; for the same reasons; the OP likely understands BTRFS better than I do. 
I should chroot first, right? manjaro-chroot -a gives this response:
grub-probe: error: cannot find a GRUB drive for /dev/sdb1. Check your device.map.
