My connectivity is very basic with just the Oppo 95 and JVC X-35 projector connected to the Anthem. Now when ever I run ARC and as owners know the RS 232 connection is below the HDMI 1 or close and when I've connected the RS232 cable I can't help but just touch the HDMI cable that's connected to HDMI-1 in the D2v as I'm tight for space behind the unit, and after running ARC basically that HDMI input stops working. The Oppo no longer talks to the Anthem so I switched everything off and changed the input to HDMI-2 and things went back to normal. Now since then I've run ARC twice and everytime I've done this the HDMI input being used stops working. I've tried shutting everything down pulling out cables putting back in while everything is turned off but the HDMI input no longer work. Tonight I tried hooking up a set top box to watch the tennis and tried one of the HDMI inputs that has failed before and after turning things back on the HDMI input being number 4 for the Oppo stopped working??
So I turned everything off as per normal and changed the cable from HDMI4 to 5 and changed the setting in the Anthem to suit and it's back to normal. I just don't understand what is happening that's rendering the HDMI inputs unusable. I thought all 8 HDMI inputs where on the same board and if one fails then shouldn't all of the them fail? It has me really confused as to what is causing this problem and it's been very frustrating. Looks like I will have to take the unit for yet another repair, this will make it the third time. Any ideas?
First off I suggest you leave the RS-232 cable screwed down tight into the back of the D2v all the time. Just coil it up neatly when it is not in use. Then you are not fumbling back there each time you want to connect it. Uncoil the free end whenever you need to use it.
The upper 4 HDMI Inputs (1-4) are on a daughter board that plugs into the big video board (top board in the unit, visible through the top vents). One possibility is that the daughter board is not properly seated in the main video board.
The usual reason for loss of signal on an HDMI socket is that the plug is not fully inserted straight into the socket. Particularly in tight space situations, the bend/weight of the cable can tug the plug away from straight. HDMI plugs are only friction fit and it just takes a small amount of shift to screw things up.
A problem that moves from socket to socket, where a socket can not be made to work again once it goes bad, suggests pin damage in the socket -- often caused by a damaged HDMI plug. As you move the plug from one socket to the next you damage the next socket, too. Very nasty. Even if the plug is not itself damaged, you can get the same sort of damage by forcing the plug into the socket at an angle instead of inserting it straight in.
To check that you need to pull out the D2v and examine the sockets and the HDMI plugs with a strong flashlight looking for bent pins.
