Problem after power cut (3x)

[goral]

I have a problem with OBH 5.2 (latest version).
I have had 3x in a short period of time (about 2h) power outages, after the last one, the VU+ has been hanging on one channel with the wheel spinning for over 30 minutes.
I have access via ftp/telnet.
I tried restarting with init 6
After restart, still the same, I switched off at the back of the receiver for 10 sec. Nothing helps.
Is it possible to fix this somehow or does it remain flash from scratch?
Thanks.

I should add that I wanted to upload the last backup image, but with the same result - that is, one channel turns on, the wheel spins and hangs.
So I uploaded another image of Open ATV - everything is going ok, the tuner settings are ok, it sees the satellite, it performs the scan correctly, but when I switch on a channel (FTA), the circle appears and that's it.
Does this mean a physical fault with the receiver?
