Pal PS1 OSSC 314p no image

[hgknapper]

I cant really find much info on how to fix but basically from what i can find online the pal ps1 sends a wonky signal that TVs sometimes find hard to read. I have sony bravia tv and so far i cannot find a way to get picture out i only just got the OSSC and really am just shooting in the dark using a Scart cable from the ps1 and direct into the TV i get the menu but when i put in a game like odd world bam only audio. I have updated the firmware to the newest is there any fixes people know about?

Yeah, PAL PS1 has an extra line compared to normal 50Hz 288p signal (314 instead of 313). This causes problems on several displays because the excess lines (when line-multiplied) is not tolerated. Some Sony TVs will not except this (W series from a few years back especially).

You can try the Panasonic hack, under Compatibility in the menu, but I think it won’t help on a Sony (doesn’t help on all Panasonics even).

Otherwise, I’m afraid you’re pretty screwed. You could try 60Hz mode if you have a modded PS1 (requires NTSC discs or ODE though).

no need for 60hz mod for the ps1 pal. if the game is pal (50hz) it displays in 50hz, if it is a 60hz game (ntsc) it will display 60hz
I have a 40w705c tv so very sensitive, taking only x2 maximum whatever the consoles (sms2, md1, md2, mcd2, saturn, dreamcast, ps1, ps2, xbox og, all pal)
for the ps1 I use the profiles found on the forum and it works.

“no need for 60hz mod for the ps1 pal. if the game is pal (50hz) it displays in 50hz, if it is a 60hz game (ntsc) it will display 60hz”

60hz on a PAL PS1 is very far off spec (something like 59.10 I think) and not tolerated by many HDTVs, at least not with a smooth picture.

OP can try the optimal profiles by all means but the underlying problem remains so they probably won’t help in his case.

My plan is to get a GBS C for the PS1 now i think it might be able to sort it out

Any scaler with a frame buffer can likely work round this problem at the cost of a small amount of input lag.
