Apologies for the delay. I got busy with my son’s spring break the past few days.

Using the test firmware, I am now getting audio from the HDMI to Component converter. I can finally play Open Ice on my Sony in 240p.

Thanks a lot!

[GeorgeSpinner]

Thanks! I’ll try to test it out tonight.

[GeorgeSpinner]

Thanks for checking. I would definitely test that out.

[GeorgeSpinner]

Update – no audio from HDMI audio extractor either.

I tested that the extractor works correctly with other audio sources.

[GeorgeSpinner]

Thanks a lot.

I tried the quad stereo settings and it did not have any impact on my issue.

I’m not suggesting you said it would, but I thought the info couldn’t hurt.

[GeorgeSpinner]

Also, yes – I tried triple buffer mode. No dice.

I think this is pretty well known, but that’s not exactly true. The OSSC can sometimes sync with a board (green light) but your display doesn’t like the signal and you get no picture.

My older Panasonic plasma would suffer from this exact scenario with the OSSC and this PCB. The light on the OSSC would be green but the plasma would just have a black screen. The plasma would not go into the no signal mode, the screen would just stay black. Sometimes setting the output mode to custom and adjusting the settings manually will fix the issue, with certain PCBs. No amount of adjustment could get this PCB to sync with the plasma, but the OSSC never had an issue syncing with it. I confirmed there was no issue with OSSC syncing by running the OSSC HDMI output to a composite/svideo converter and image displayed fine on my CRT. My LG OLED does not have any problem with this PCB on the OSSC and works in the Generic mode.

The 5x can’t even sync with the PCB and has no way to manually adjust the sync settings. I believe the message is “check signal”.

If I change the input mode on 5x to composite it displays a black and white image of the PCB output with garbage at the bottom of the screen. I assume this is the sync information. I believe it also displays that the signal is 50hz.

There issue is the 5x cannot sync with them PCB.

[GeorgeSpinner]

Yes. 54hz, I believe. I’m sure that’s the issue. I’m just surprised because the OSSC handles it fine with the Generic 4:3 setting.

I’ve tried the minigun Supergun and the axunworks mini Supergun. Both via component cable. The minigun is using HD Retrovision competent cables.

So in your case it may be some bridged pins on U1 or U17 too (U1 gets pretty hot – maybe a tiny solder ball was there and moved thanks to the heat and some flux residue).

Thanks for the suggestion.

I took the heatsink off and had a look at U1 and then U17 but I didn’t see anything obvious wrong.

The USB Blaster I ordered from Amazon arrived this afternoon.

I was able to successfully flash firmware .87 onto the unit.

After restart it was working again.

I flashed firmware .88 from an SD card and I am back in business. All my settings and profiles were even still there.

I am curious why this happened.

At the time this occurred, I was using the MiSTer FPGA to the OSSC using an HDMI to component adapter.

I had the MiSTer configured with direct_video=1. I am wondering if it did not like the sync signal? My Sony CRT had no issue with it.

I was just fooling around because the Mister component out via the IO board is pretty dark. The brightness isn’t an issue with the OSSC, but on the CRT it is.

I regret fooling with it.

Thanks again for the help.
