H3000 Issue, stuck in LOCK


Hey there everyone, I'm new to the forum, I have that MIDAS H-3000 which is sadly stuck in the LOCK mode.

As soon as I press on the system button, the segment display tells me I'm in LOCK mode.
The UP and DOWN button doesn't do anything, the confirm button either. If I press CANCEL, the LOCK disappear.

I'll mention that the LOCK LED is lit but it's really dimmed.

I measure the Power on the output of the 12V REG1, I have 12V.

Something weird is that I have 11.2V on the XL Auto Central Control Panel board.

Anyone ever experienced this problem? Would it be more related to power or maybe a logical gate?
