wired problem with some hdmi and xBox 360

rycerzCzeslaw · Nov 29, 2015

Hi,

Before open this ticket, i've read and tested a lot of stuff - nothing works 4 me After connect my xBox to TV via HDMI cable - i have blank screen, no video and audio (but TV shows that something is connected to the HDMI port - it's indicated). When
i power on xBox - it's still info that "no cable connected".

TEST1:

My xBox 360 is working perfectly with d-sub cable. When i try to connect it to my TV (Sony Bravia) via HDMI cable - doesn't works. I've tried with another xBox - works perfectly with this TV (all 4 HDMI ports tried in this TV, 3 different HDMI cables checked).

TEST2:

Samsung TV (UE55J6200), HDMI (3 ports tried) - my xBox doesn't works, another xBox works perfectly. D-sub cable - my xBox works fine.

TEST3:

Dell monitor with HDMI input: my xBox works perfectly via HDMI (tried with my 3 HDMI cables which i've tried before)

TEST4:

Samsung TV (don't know the type, some new, top model) - my xBox works perfectly with all hdmi ports and all my hdmi cables. I've tested 640x480, 720p, 1080p, 1080i, autodetect... All OK.

I've tried with:

- reset video settings (Y + RT while starting)

- reset memory (including format disk)

- blind change resolution

- change resolution on new Samsung TV and reconnect to Sony TV

Noting helps my xBox to work :/

Please, help

:)

Changeing inputs restarts my input.

There is a problem with many third party audio adapters in that they're wired to identify themselves as a full AV cable to the Xbox 360. The original audio adapter which is no longer in production, was wired to have its own unique identity.

So in a nutshell, the Xbox 360 thinks it's supposed to be sending composite video over the AV output, not just audio.

And this highlights a limitation to how the Xbox 360 handles video output. For technical and some licensing reasons, it cannot output HDMI and analog video at the same time.

When the Xbox 360 boots it prioritizes HDMI and tries to establish a connection with the receiving device. If there is no response, it instead checks if there is anything connected to the analog AV port and if so, switches over to analog video output. If nothing
is connected to the analog AV port, or a properly wired audio adapter, the Xbox 360 simply keeps on waiting for the HDMI connection to establish.

The same thing happens if the communication over HDMI is interrupted. If there is nothing connected to the analog AV port or a properly wired audio adapter, the Xbox 360 waits for the HDMI connection to re-establish. If there is an analog AV cable connected,
it reboots so that it can configure itself for analog video output.

To solve the problem, you either have to crack open the audio adapter's connector and re-solder it to make it identify itself as an audio adapter, not as an AV cable. If you have a soldering iron and want to take a crack at this, you should be able to find instructions
on the net for which pins to wire.

Another soloution is to try getting hold of a used original audio adapter, or a third party one that is known to be wired correctly.

Of course the most dramatic and expensive solution is to get an Xbox 360S. As stated by Bill Gates in an interview once: "Microsoft has never been accused of not knowing how to make money".

And so it ends. The problem was with the HDMI cable that came with the console all along. For some odd reason, it works fine hooked up to the Xbox 360. I can't believe such a painful problem is all caused from a silly wire. Thanks to everyone who helped.
I hope anyone who may have had this same problem can find this solution.

I believer I am having the same issue, my HDMI was working fine, no problems. I bought some turtle beaches, forgetting I needed an HDMI adapter, so I just used regular A/V wires. I just now bought the adapter a month later and now my HDMI isnt working at
all. Continues to say no signal on my TV. I used different HDMI wires so I know its not fault of the wire. Help please.
