Hardware Rapid Blinking Led Switch Dock

[PIXeL_92]

Hello all,

Got a faulty Switch that no matter what dock I put it in I get a flashing green LED.

I can't find any shorts on the board.

It turns on, charges and works fine Handheld.

I have tried:
New USB C port (checked and I have continuity on both edges of the connector)
New PI3USB IC
Several different docks and Official PSUs
Checked Continuity on chokes (all have continuity on both sides.)

I'm going to try tomorrow replacing the M92T36 chip to see if that makes a difference after checking pin 5&6 for voltage readings.

Anyone suggest what else to check.

Thanks

I bring good news.

I am guessing the PI3USB wasn't getting the voltage it needed as I have just changed the M92T36 IC and we are back in action, tablet and docked mode now both working.
