Hi marcobb0312,
IIRC fault 61 is a comms error between the ARM chip on the digital PCB & the Bridgeco chip on the streaming PCB, so either a ribbon has become dislodged or you have a hardware fault.
If so, it’s usually the streaming module at fault.
If you want to have a look yourself, check carefully the two white ribbons that are between the small PCB on pillars & the PCB below it. (It’s the one where the Wifi aerial connects). Make sure the brown locking bars are securely pushed down & the ribbons are seated fully home.
Regards
Neil.
