Hoping this hasn’t been answered somehow already but my searching didn’t turn anything up.
Today I got an RGB modded NTSC-J N64 and it was working perfectly until I connected it to my Elgato HD60 Pro, not realising it didn’t support the OSSC. The output started dropping at random intervals (1s-10s) with the red LED lighting up each time it did so. This persisted even after disconnecting the capture card. I have tried resetting my settings and cycling the power, but to no avail. At most after a power cycle it will work fine for a few minutes and then start again, albeit less frequently
I am using an ASUS VG248QE monitor, which is confirmed to work with the OSSC.
As I said i’ve reset to default settings.
The OSSC is v1.6, I ordered it a few weeks ago. I haven’t tried updating the firmware.
The OSSC display says:
AV1: RGBS 263p
I currently don’t own any other 240p source besides a unmodified PAL N64 (composite only) and a wii which will only do 240i or 480p.
Here is a video I recorded showing what I mean: https://youtu.be/46wVUEMQ3JIFebruary 8, 2019 at 8:10 PM #25151
Something else I just considered – before today I’d been using it with my wii without problems, and the hdmi out was initially connected to a splitter powered by usb. For some reason the hdmi cable was carrying this power to the OSSC, such that I could turn off the switch and unplug the power cable and it would remain on. I stopped using the splitter for fear of this damaging the OSSC, but perhaps it had already damaged it in some way? I’m hoping this isn’t the case.February 8, 2019 at 8:25 PM #25152
If your Wii still works with it without issue, I’d be inclined to blame the RGB mod. Do you know what kind of RGB mod it is (simple bypass, or a Tim Worthington/borti board?) and who installed it?February 8, 2019 at 8:45 PM #25153
I don’t, I’ll crack it open and have a look now. I bought it from consolepassion.February 8, 2019 at 9:11 PM #25154
Alright, just looked and I can’t see an amp? Just the VDC chip wired to the output. I don’t know if that type of mod could cause problems but I have a borti amp from when I planned on doing it myself. If I can’t solve this by tomorrow I’ll desolder these wires and install the borti.February 8, 2019 at 9:20 PM #25155
Weird. I expect that kind of mod would work fine with a CRT, but clearly it has an irregular sync that a contemporary display is not going to tolerate; plus, it doesn’t have the advantages of having an amp, LPF, and sync buffer that the bypass boards provide. Definitely try with the borti board.February 9, 2019 at 12:10 AM #25157
After installing the amp, everything is working as normal again! Any mods, feel free to delete this post as the issue wasn’t to do with the OSSC.February 9, 2019 at 3:54 AM #25159
I say leave the post. It’s entirely possible someone else will end up with a similar mod, experience similar behavior, and then find this thread. 🙂February 12, 2019 at 5:00 PM #25184AnonymousInactive
Just a side note in case you ever need another 240p source to test with in the future, or just for shirts and goggles – the Wii will output 240p for virtual console titles (may require softmodding, depending on the title): https://www.retrorgb.com/wiivsclassic.html.
