I’ve been given an FVP4000T to repair (I volunteer for my local repair café)

There’s no led power indication. Checking the numerous supply voltages on the pcb I find the 5v standby, 3.3v, 1.5v all good.

The 1.0v on the underside is also good, but the 1_0v BCM3461 test point on the top of the board is only 0.06v.

The 4R7 coil near U1600 has 0.0v

The coil near U4307 is 0.16v

I don’t have a circuit diagram so don’t know what the voltages should be, so if anyone has some ideas, I’d be grateful.

There’s a 6 pin smd marked ML5BA which I guess is a v regulator. Any help where to get info on this would be appreciated too, as this is associated with a couple of the coils mentioned above.
