Some slight liquid damage signs around rear edge.
Thought ok probably damaged 3v42 line. Check it getting 3.38V seems low. No obvious damage around the boost IC.
Checked ACOK line from u7000 0v
Check ACIN 0v
Replaced u7000 due to internal short pulling ACIN low.
Now have 4v on ACIN and ACOK reads 3.3v
Still dim green light. Also inrush MOSFET first gate isn't opening, so no pp_g3h being made either.
Is this still a u7000 issue or is the 3v42 too low causing a weird issue.
DCIN is 16.6 -16.8v and fluctuates quite a bit not a steady voltage
