PS2 scart question

[wyvernshill]

Hello everyone,

Quick question, a while ago i posted something similar (i thought i had an original PS2 scart cable) but here i go.

I have a Logic3 PS2/PS3 scart cable (http://www.muizenshop.nl/p/logic-3-rgb- ... ps2/37395/ or http://www.amazon.co.uk/Logic-3-PS931-L ... d_sxp_f_pt).
I bought it years ago and it worked great on my PS2 and PS3 while they were connected to my old CRT TV.

However, if i try to use this cable on the xrgb mini i seem to have sync issues, the image keeps blinking away no matter what sync level i use, level 9 gives me a fairly stable image with sometimes dropouts.
When the image is displayed it is far more crisp than the component cable i have as well. no matter what settings i try that i found in this forum, it seems the picture is never as clean as the one provided by the scart RGB cable.

Someone posted a link that explained i needed to mod the original PS2 scart cable to get rid of the sync issues. In the original scart cable there seems to be a little circuit board, cutting the power to that board would solve the sync issues.
Unfortunately this Logic3 cable has no such circuit board at all. If opened there are just the normal direct connections to the pins. I cannot take a photo of it as i do not have a camera.
Does anyone have this cable and know how to solve the sync issues with it ?

I know i can use component but as i said before i cannot get the image as clean as the scart cable and using 480P is not a concern for me, it even displays worse in the mini.

Thanks for the help !

that doesn't make sense. The additional board on the original Sony cable is a 12V to 5V converter. The 5V from the board are fed to pins 8 and (through a resistor) to pin 16 of the Scart connector. This tells a CRT to switch into RGB mode.

The XRGB-Mini ignores these pins. They're not even connected on the adapter cable. Hence cutting this it's power supply shouldn't change anything.

You can still try but cutting pins 8 and 16, but I doubt that it makes a difference.

Fudoh, as usual you are an omnipresent force on this board ...

Do you have any idea what could cause the sync issues or can you point me to a good ps1/ps2 scart cable that is still on sale today ?
Most ps2 scart cables are either very cheap (bad) cables or are not for sale anymore (original ps2 scart).

Do you have a PAL PS2 or a NTSC unit ?

With a PAL machine your best shot would be to use luma (black/white image from s-video) instead of composite video for sync. This requires a cable that's modded to use the luma pin instead on the Playstation end of the cable. Same thing can be accomplished by changing the pins (cutting one, bridging another) on the Playstation's AV port.

Retro Accessories in the US sold such cables last year, but I haven't seen them in a while.

Nope, i have an NTSC ps2, i imported 2 of them from Canada a few years back, i still have a silver one unopened in the box.
The reason was simple, i wanted to play the Xenosaga series, and those never came out in Europe (well i think they gave us the 3rd one).
Another thing was the PAL/NTSC 50 and 60 hz problem. I wanted my games to run at the correct speed :p

a NTSC PS2 really shouldn't cause any problems on the Mini. You said you opened the Scart cable and had a look ? What components do you see ? If all the pins are just straight connected, I would start by adding capacitors to the RGB lines and see if that fixes your issue.

You could use this - http://www.videogameperfection.com/2014 ... le-review/ and an Extron interface. Considerably more expensive, but it would have the added benefit of enabling you to use 480p too.

I'll try to take a picture tonight, might use an older cellphone i had lying around. The quality might not be too great :S

Ok here i got a few pictures of the interior of the scart cable. I know it doesnt seem shielded and the hot glue doesnt give much hope either but anyway ...

Sorry if they are too big or do not show up, i never tried uploading pics on the net ...

Noone has a response anymore ?

[Fudoh]

The caps are were they belong, but it's a shitty job in terms of soldering and applying hot glue. Either you rework the cable or you just get another one.

Firstly, I think the problem is not with the sync as it is more consistent with the refresh rate. I think the cable is OK, not pretty. The problem you are experiencing is the same as me, I have tried both a modded PAL unit and an NTSC unit and both had the refresh problem on the panel. I used the official SONY EURO-SCART cable as well. My NTSCJ Saturn works perfectly on the mini, except for some noise issue (Have they ever fixed the LPF problem??) on solid background. I have tested both the first version and the N version of the mini and each revision is exhibiting the same problem.
