after many months of working, my DM800 stopped tuning channels.
after rebooting it, the receiver dont finish boot.
after changing the kernel cmdline to output to serial console, i see these errors:

DVB: registering new adapter (BCM7401)
autodetecting NUMs...
addr=41, data=00
ret:2
Found: Slot A, ID: 06 (by CA)
Initializing adapter 0 (DVB-S2)
special BSBE2 treatment:
addr=45, data=ff
fe: read ret=-5
cx24116: i2c error
(failed)

and so on forever last 5 lines...

any hint? i hate sending back to DM and wait months to have it back...

is replacement DM800 tuners availables somewhere?
