Hi,

I can't see any error in bisplay because is off and does not open. I disconnected from the battery but nothing.I checked the connector plugs under the plastic cover too and are ok.
The problem begun after they connect the battery from the end of charging.
A strange thing is that from the fan which cool the units , I hear a noise like tzzzzzzzzzz and dos not work.
What do you mean emergency open? How I can do this?

Thanks
