OSSC + Sony XR A90J + PS2 Component screen goes on and off

[fireball]

I have just bought one of the new v1.8 OSSC’s and updated the firmware to 1.08. I’m connecting my modded fat PAL PS2 via component cable to the OSSC and connecting the OSSC via high quality HDMI cable directly to my Sony XR A90J which is a 4K OLED tv.

I’m trying to run NTSC games in 480i, ps2 component out is set to YPbPr. Screen goes off about every 5 seconds, sometimes a bit longer or shorter. Doesn’t matter if 480i/576i is set to passthrough or not. If anoyne has any suggestions I would be glad. Have read other threads on the net which suggest to make sure to use a HQ component cable from HD Retrovision. My cable is 20 years old but I’m pretty sure it was regarded HQ back then, brand is Blaze by Xploder. Before I invest another 50+ euros (current price from european seller) for a new component cable I want to make absolutely sure there isn’t a known problem with my tv or that a new cable is even likely to fix my problem.

Otherwise I sadly don’t see any other other option than to return my OSSC. 🙁

Does OSSC also lose sync (red led blink)? Can you try adjusting sync Vth from options to see if that would make a difference?

[fireball]

led is not blinking red, it’s green even during the picture dropouts. I tried adjusting Analog sync Vth but no effect other than the screen going completely blank and the led red when the value is set too high or low.

I tried a few additional things to make sure the cause is not my cable or ps2:

– I lent a HQ RGB SCART cable from a friend and with this I connected my ps2 to the OSSC, same problem

– I hooked up my ps2 to the CRT tv 0f the same friend with this cable, no problems

– Last I tried a component -> hdmi adapter instead the OSSC between ps2 and my tv, no problems (well, besides from the picture being ugly and way too dark and the reason why I bought the OSSC in the first place…)

It seems I’m just out of luck with the OSSC and my tv.

Have you tried a different display with OSSC to see if the OSSC possibly is faulty or if it’s some kind of compatibility issue? I presume the test pattern is rock solid?

[fireball]

Test pattern is steady. Will try device at a friend soon and report back here.

[fireball]

Working fine on other displays, seems it’s just my tv.

Quite weird behaviour from this set. Could you test a PS1 game on the same set running on the PS2 before returning the device?

[marqs]

Could you also try DVI mode (Output options – TX mode) to rule out any HDMI metadata issues?

[BuckoA51]

A downgrade to the old 0.xx firmware would also be interesting to try (though I think OP has already given up and returned the unit now).

@marqs  I increased the Analog sync Vth from the default 123mV to mid 247mv as increasing to higher mV values delays the signal drop. The signal dropping seems to stopped at 247mV for now.  Why is the signal dropping at 123mV and will there be a fix implemented for the next firmware update?

I just dusted off my 1.7 ossc and did the r35 to u21 wire mod. I updated to the latest v1.11a firmware and using the default profile (no profiles added). My tv is a sony bravia x90j on the latest system update. My PS2 model is scph-30001 (in ypbpr video setting) and I’m using an hd retrovision PS2 component cable connected from the console to the ossc, and Belkin 2M Ultra HD HDMI 2.1 cable.

Edit: I increased value to 293mV but the signal still drops but not as frequently. Increasing the value to 304mV causes the tv signal to completely drop needing a reboot.

Edit 2: I changed the following under the settings, Sync opt./ADC PLL BW = Low and Compatibility/Allow TVP HPLL2x = On. Also changed the value back to the default 123mV in Analog sync Vth. The black signal dropouts have stopped (for now). I’ll post back after a long gaming session.
