OSSC signal randomly dropping

[marqs]

I understood you tried 2 sets of cables which both had the issue? Could you still try the SCART cable with PS2 set into component mode (AV1_YPbPr input mode on ossc) to see if the problem is perhaps related to color burst noise?

I seem to be having a similar issue with my PS2. The signal will drop out for a tiny fraction of a second, enough to make my display temporarily go black but video capture just shows the OSD popup.
My PS2 is a SCPH-50001 model, using the HD Retrovision component cable on a rev 1.7 OSSC with the hardware mod done running firmware 1.09. I do not have another cable to test but I don’t believe it’s the issue.
It doesn’t seem to be related to any particular setting, even with defaults it can still happen. I’m not able to make it happen consistently, sometimes it’ll go for several minutes without an issue and then it’ll drop out multiple times within a few seconds.
This only started happening today. Maybe it was related to me updating the firmware recently? I don’t really have any way of knowing for sure.

I took off the case to check the wire I soldered and it broke off when I touched it. While trying to solder it back on I bridged TVP pin 24 and 25, and in the process of removing the bridge I somehow broke pin 25 off completely. I now realize that I don’t have the proper soldering skills to do this, so I’m just going to leave it as is and downgrade to 0.90. If I’m understanding the schematic correctly pin 25 is NC in a regular 1.7 board anyways, so it should still work fine on original firmware?

So far on 0.90 it has been working fine and I have not seen a sync drop while using my PS2. I’ll edit this if it comes back.
