Hardware Switch only docks in reverse

[tomsek68]

This board had ALL of its pins ripped. I have rebuilt the port with a working board at hand.

• It wont dock when i place it in a (nintendo) dock. Behavior is normal except there is no picture on the tv.
• It will dock, if i disassemble the dock and plug it in reversed.
• The working board docks both ways.
• PD negotiation works in both direction, 15V OK on the board.

What pins should i check? All of my checks showed no error in wiring, but obviously something is wrong.

Broken dock? Broken pins?

• This C socket was salvaged from a broken dock. I had to use this because it does not cover the missing pins. I have used jumper wires.
• I have left out some ground pins (2 of 5) and a VCC (1 of 4). Definitely not the problem.
• The blue wire is just a spacer between the two rows.
• All pins look fine with beep mode.
  • I have tested it with a standalone dock plug. (from plug side to PI3USB side of filters)
• To my knowledge every signal pair should be OK to dock succesfully.
• The dock works in both direction with many other switches.

I had the time to buy a third party dock. This one is made by KOBE. It works flawlessly with this. WHY?
I will disassemble this one and try reverse. I guess it should not work that way.

Hello,

Have you correctly mapped the wires according diagram ?

 

[tomsek68]

I have used the original pads (what remained of them), with straight jumpers.

Today I rewired the port (straight to filters), and may have killed M92T36.
Is CC1 supposed to be 5v-ish?
Also the switch wont negotiate with the charger now.

• One way it sends 5V
• The other way it jumps between 2 and 3V.
• Original dock blinks fast the second I drop it in.

Is CC1 supposed to be 5v-ish?

according to wiki:
USB Power Delivery uses one of CC1, CC2 pins for power negotiation up to 20 V at 5 A...

 

[tomsek68]

It says it uses CC1 and CC2 for negotiation. Nothing about voltage levels.

EDIT:
The minimal configuraton for charging is VCC, GND and/or CC1/CC2.
Charges with 15v.
