    Meta Quest 2 not turning on - pulsing amp draw

    Hi
    Following problem regarding a Quest 2 I got with broken USB port and "not turning on".
    After replacing the USB/Audio port + cable the Device still refuses to turn on. A USB multimeter is showing a pulsing amp draw ranging from 70 mA to 1.2 A and back.
    All obvious caps measured good (no short).
    A visual thermal inspection showed two ICs glowing up also pulsing.

    One was a Qualcomm PMIC PM8150B which I suspected to be the culprit. But replacing it with a china-replacement made no difference.

    The other one I can't identify. It looks like a tiny BGA with marking "HEBV BCD". It also seems to be related to the battery charging circuit. Does anyone know this part?

    Has anybody another hint as what I should look for further?

      I have the same model with identical issue. Tested new battery, checked caps as well. Did you solve the issue?

          Sorry for the late reply. Somehow I don't receive notifications for new posts.
          Unfortunately I couldn't solve it untill now.

              820-00165 pulsing and stuck at S5
              by speggio91
              Hello everyone!

              I have this board that got slightly water damanged and it is stuck at S5 state. It pulses once every 5 seconds.
              When connected the magsafe 2 to the bench psu, the current goes from 0.02A to 0.10A when is pulsing.

              When using the genuine magsafe 2 charger, the light turn on and it became green and then amber. The fan is not spinning.
              When I tried the SMC bypass mode, the fan spins a quarter every 5 seconds and the pulsing is still present every time the fan spin.

              The pulses are present in the CPU Vcore rails on L7320 and L7310....
