Replaced U1950. Now it's on. Should I replace R8164 or just keep the board running without it

EDP_PANEL_PWR is 0V also Pin 5 of U8300 is also 0V. no shorts

I check this morning. No Fan Spin. R8167 is not getting 3V at Pin 1

820-02100 The PPBUS Fuses. Both PPVIN_5VUSBC are also 0.110 diode mode to ground

Diode Mode with LCD Connected is 0.493

Removed the Fuse. PPBUS is .120 and PPBVAT is .453. Is I shorted ? I injected voltage and not drawing any amps. (0.002) I removed RD590 and PPVIN_P3V8AON jumped from 0.120 to 0.450 which is the correct range as per openboarddata. Hence I feel there is a short. How to proceed ?

All my batteries are okay. Checked on another board. The customer original battery is faulty. But the issue of new battery on the customers board issue remains

I don't have it and neither do I have the time with this particular case. let me swap the battery with a running a1706 and check.
