How do I remove or disable PIN13 from one end of a HDMI cable. I just got an enhanced DVR(ARRIS DCX 3600XNG)from TWC.After installing I found that I lost CEC control from my Onkyo TX-NR 838 to my Vizio M43-C1.I also lost the ability of hearing sound through my system(ok through TV speakers)when I stream Netflix or Amazon.I have read on TWC forums of a fix for the CEC problem by disabling Pin13 on one end of the HDMI cable (the end that plugs into the Onkyo from the ARRIS DVR) What would be the best way to do this?

Are products like that safe?

I found a thread where a poster reported that some devices are using HDMI pin 13 for grounding which could cause problems if you disconnect it, which is what the device is doing.

Opinions?
The OP here posted the same question in that forum.

Here's the pinouts for commonly found HDMI connectors:

6    TMDS Data1+
7    TMDS Data1 Shield
8    TMDS Data1-
9    TMDS Data0+
10   TMDS Data0 Shield
11   TMDS Data0-
12   TMDS Clock+
13   TMDS Clock Shield
14   TMDS Clock-
[B]15   CEC[/B]
16   Ground (for DDC, CEC, ARC, and HEAC)
17   SCL (I²C serial clock for DDC)
18   SDA (I²C serial clock for DDC)
19   +5V Power (55mA Max)
Any well-designed adapter that connects the the type C and type D connectors to a type A cable would have the correct signal routed to the appropriate pins for the type A connector. The type C and type D connectors would most likely be found on laptop computers or portable video gear like cameras or portable disc players.

So I live in Trinidad and Tobago and we just got a new Digital HD Cable box Model: DMS1004HDHM

Guess what problem I am having?

Whenever I plug in my cable box with HDMI, my bravia sync between my Sony Soundbar and Sony TV stop working.
Over composite I have no issues and no HD. There are no component out options on this Cable Box.

Took a flat head and punched out Pin #13 , all issues solved.

Thank you guys so much for the correct HDMI wiring diagram and the advice.
