TH55 does not recognize battery after display repair
I have a problem on 2 TH55 which I just tried to repair (switching the displays).
Actually the display exchange went fine without major issues. So the 'bad' TH55 got the broken glass front and the 'good' one got the fine display.
Both TH55 were running without issues before the repair attempt.
After the assempling both TH55 are not recognizing the batteries. On the cable power supply (or cadle) they both work and boot though they behave like after a power loss. As soon as I disconnect them from the battery source they are dead again and cannot sitched on. The batteries are fine and fully charged, I checked that.
On the cradle or connected to the cable power supply the power LED is green and in not getting orange for charging, although the battery symbol tells 'charging'.
So I wonder if some of you here have seen this kind of issue and have a solution?
