PSP Go S-Video

Post by d0kterfreddy » Sun Sep 09, 2018 9:54 pm

Was there an official S-video cable available for the PSP go? If so does anybody know the pins for S-video. I would like to modify a spare component cable to S-Video.
The thing is I would like to hook up my PSP Go to a PAL CRT. And the CRT has S-Video but no component.

I saw some unofficial cables. but they are rare to find and expensive.
Maybe a different question. In the component cable there is a 42k resistor on pin 15. What is de resistor for composite? I would like to test something.

Does anybody have a link to the datasheet of the OKI L86V7657 9175902J chip. If so mayby I could learn something from that.

I found a solution for my problem. Here are my findings.

- I used the pinout from http://www.acidmods.com/forum/index.php?topic=34981.0
- Bought a PSP2000/3000 composite/S-video cable.

Next I de-soldered the proprietary connectors. And tried to pragmatically find the correct pins. Here is the result:

PSP GO pinout:
1: GND
2: D+
3: D-
4: GND
5: ???
6: ???
7: +5V (Not from USB)
8: +5V USB
9: ???
10: Component Blue / Chroma
11: ???
12: GND
13: Component Green / Luma
14: ???
15: Enable Component Video Out
(Resistance 50k to GND)/
Enable Composite/S-video Video Out
(Resistance 5,5k to GND)/
16: Component Red / Composite
17: GND
18: GND
19: Enable Audio Out (when Grounded)
20: GND
21: Right
22: GND
23: ???
24: Left
25: ???
26: ???
27: ???
28: GND

I can confirm that it works. It has been tested on an HDTV.
Now I can use my PSP GO on a PAL CRT via S-video. Unfortunately my Trinitron died on me recently. but that's another subject.
