My new battery finally arrived...

The device has been in the cupboard for a few weeks while I waiting.

Now when it boots all I get is this:

I tried swapping the new battery in, it does the same thing. Actually a small difference...the new battery boots it, the old one doesn't which seems to point me to the charging circuit.

I also now have a hot air gun so some reflow on the weekend might be in order, as suggested by knc1

I will disconnect new battery and investigate the charging circuit further with a better magnifier.
