I replaced the broken LCD screen with a new one and the screen is not working. All seemed to go very well with the remove and replace.
The screen stays on the Critical battery screen only, as this was the way it was received from the shipper. The battery and charger work good.
All other conections to the board seem ok. Is there any way to check the LCD screen alone, that's not a bad one from the shipper without sending it back?
I've open, removed and reinstalled the LCD screen many times, this I can do this with my eyes closed now. Any help on what to do next?
Thanks and best regards,
