820-3787-a not power

[tipoti]

The device does not turn on. I tried with a different battery. orange light is on.

It stays at 0.04a amperage

=PPBUS_G3H: no voltage
PPDCIN_G3H_CHGR : 20v

Check diode mode to ground at PPBUS_G3H.
If bad, remove both F7140/1 and see where bad value remains.

I replaced u7000. The device was turned on. However, it drew a current of 4-6 Amperes and burned. Now I changed it again. The device turns on, the orange light is on, but it does not draw any amperage and does not charge. It just turns the device on. 0.0 Amp
