Macbook A2442 Came in as Not turning on.
PP3v8 shorted.
Injected voltage. U7700 heating up. Short removed.
PPBUS is 12.3V
3V8_on is Present
AMP Meter stuck at 5V and drawing close to 0 Amps
Pp1v_s2 is 0.300-0.400V
3v3_s2 is 1V
PP5v_s2 main is missing.
U5700 is behaving weird.
If i probe around C5700/1/2 to check voltages. it heats up - amps rise to 700-800.
After this incident 3v8 goes missing and even pulls low amps when injected with 1V showing heat spikes at U5700.
i have replaced 2 U5700. Still the same.
