Update

Thank you Oldturkey03, please excuse my english, its terrible for doing technical questions.

The apple service told me something like this:

Unit was in contact with liquid (possibly wine), especially severe marks on the logic board (motherboard). Thorough cleaning was performed. Unit runs but a short circuit on the connector and logic board IOBoard found. The only thing that does not work on the unit's right side (USB connector, HDMI and SD card) and IOBoard logic board damaged wire.

But then they told me:

We contact you to notify you after a second check the unit does not respond. The computer turns on but no picture.

Logicboard and the topcase are probably damaged by the effects of liquid

Do you think that there is something that i can do to repair it?

Than you very much for your help.

Regards,

Germán.

germanluongo, I am not exactly sure of what your question is. That particular contact is one of the contacts that connects to ground. Any component failed in that part of the HDMI Redriver (on RIO) circuitry can cause this.

germanluongo, your English is fine. Yes, looking at the schematic I can see why your HDMI is no longer working. you will have to replace the connector as well as the cable to possibly get fixed. Hopefully it just shortened the connector not the board.
