HT-E6750W firmware downgrade

[PatrikCH2019]

Hi Guys

My current version of the firmware is 1024.0.

Is it possible to downgrade this version to the previous one?

I had a system crash (power loss). Since then I don't have a HDMI signal. The tone is still working. I think the firmware is corrupt now.

Maybe a downgrade and a reinstall to the version 1024.0 again will solve the problem.

Please let me know. Thanks!

Kind regards,
Patrik
