BMV bL 1.02 error -No backlight flashing

I have a bL 1.02 error

This is the background

I have battery and BMV 702 installed in my 4x4 trailer for 6 years

While in storage, battery is constantly connected to Blue Smart Charger

One day noticed bL 1.02 displayed on BMV 702. No flashing, no backlight on

Check all advice on forum - tried everythin, nothing changes the situation

Took second spare, brand new BMV 702 and connect it in place of existing BMV, got the same message

Connect the second BMV 702 directly to other battery with its own shunt, still get the same message on the new one!!

Cannot reset, cannot do anything. I now have 2 BMV's that is not working.

Assistance will be greatly appreciated

Is their no direct tech talk with some Victron experts?
