psone screen help needed please

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.

It would help if you told us the voltage and current your screen needs.

Not even close. 750mAh is about right.

I realized that you said what screen it was after I posted that, and didn't feel like editing. Squee's right, without the LED mod, the screen takes about 750mAh. The PS1 screen can't run at more than 9V, and it is screwy at that point to.

i found out that using a 10 ohm resistor i can get ~7.2 volts from 12 volts.
