PSOne LCD Pinout

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

On gamesx.com, they said i need a 220uf capacitor in each of the RGB lines to get an acceptable picture. Is this true for the psone lcd, because i only think its true for him because he uses computer monitors. Has anyone connected a psone to the psone lcd using RGB and get it to work successfully. It's also saying that i need a LM1881 or similar circuit to strip the sync from the video line. Do i really need all this stuff? Thanks.

You don't need the caps since the psone works with the lcd w/o caps. Use the s video y line as sync and you won't need to make the circuit. Use the psones svideo y out as sync. Remember that the sync in on the lcd is port 1 pin 3.

Could somebody answer my question about the 7805 chips? I think it would greatly reduce the power consumption if these were replaced by a direct 5v line running to the system in both places...has anyone tried this?

You know, half the point of registering is using it, though its sometimes kinda picky. If you can type your name when you're typing a post, you aren't logged in. :)

I know they sell 50/60Hz converters, but from what I've heard they suck up a lot of power and wouldn't be good for a portable. But if you're just using it for a console, that might work pretty good.

yeah i know those... but the arent cheap... and i thought perhap its possible to change something on the board of the LCD screen to get 60Hz running.
