XMC-1 Issue (HDMI handshake?)

[Ritter]

I've had and enjoyed and XMC-1 for a few years and never had any issue- until last nite. I was getting green screen from most but not all HDMI input sources

For starters I have 3.1 firmware and 1.4 HDMI .

I have 4 HDMI inputs with DirecTV, AppleTV, DVD and FireTV. All previously worked without issue. Last night all but the Directv showed a greenscreen- without any changes in cables or settings. The DVD player would briefly show the screen then revert to green. I tried a hard reset on everything (unplugged for 20 mins)- now ALL inputs show greenscreen- but I do get sound.

Any idea whats going on?

Cable failure?

Once in a great while your XMC-1 may need a deep power cycle. But before that, if you swap a source known working to the input where there is no output, does it behave the same? Also cables do fail, but not as much as you might think. Also be certain HDMI cables are fully seated. Never was a big fan of any cable that is like USB a slide in and I think it is connected affair. Really quite stupid honestly. An Ethernet like connection would be better but I digress. You may want to just try reseating cables where there is not output, or take one known good output of that device's cable and connect it to a HDMI connection that is green screening you. Worth a shot.

Thanks for the quick replies.
Cable failure doesn't explain why one source was working and the other 2 not and the third intermittent. But there is one long HDMI out to the PJ. I'll bypass it and see what that yields.

Try swapping out the main HDMI cable (XMC to video display)
Firmware 4.1 is the last and most stable for the original board. I would do the cable, then the firmware upgrade in that order. If the cable doesn’t do it first you may have a bad board in there. 4.1 Should yield the final story.

I’m with you vcautokid, on the HDMI interconnect.
Why it’s not a din connector configuration AV/interface is somethin’ I’ll never figure out, but what do I know.
Today’s HDMI (to me) will forever be like putting a square peg in a round hole.

Well I’m back up and running. I did so many things in totally unscientific method, all at the same time, but I would guess it was just changing from one HDMI outputs to the other. 🙄

Now all are back and working as before 😅. Do you still recommend upgrading to 4.1 firmware? (Now) it ain’t broken, so ... what will this fix or improve?

Good news! Glad you’re back....
I hear you on if it ain’t broke don’t fix it, but this is an upgrade not a fix. The best of everything the XMC can deliver with the original board is driven by 4.1.
The ability to reset all filters without a factory reset is one of many.
OSD is improved with more customization available. A number of additional things that noticing depends on how your use.

Thx. I’ll definitely upgrade. Good week to do it too.
