I have a Panasonic 3DO model FZ-1 which turns on and loads the main screen, but does not play any type of disc. I took the entire thing completely apart, cleaned the laser, detached and reattached all of the ribbon cables, greased the worm gear and guide bar on the laser and...nothing.

When I put ...

I'm just trying to make a "no frills" portable NES. My original thought was to power the screen from the battery, then pull the +5v from the 7805 regulator on the back of the screen to power the NES board. From the sounds of it, this may be the wrong route to go...

That being said, would it be ...

Yep. Testing the disconnected battery with a multimeter. Somebody suggested I use a 7808 to drop the 9.6V battery down to 8V output for my PSOne screen. Evidently, that's the wrong route, eh?

Would a modified 7505 regulator be okay? I think there's a way to get a 7505 to put out more than 5V using ...

The battery is actually a 9.6V NiCd battery. I previously wrote NiMh. Not sure it makes a difference unless you're charing it. I charged it overnight (it automatically shuts off when it's "charged") and when I tested it this morning, it came in at 10.65 Volts. That slowly dropped (about .01 Volts ...

I have a rechargeable 9.6V NiMh 1000mAh battery going through a 7808 regulator, to a power switch, then out to my PSOne screen. When I flip the switch, the screen occasionally turns on, but appears to flicker. It's as if there isn't a constant stream of juice going to the screen. Some other times ...

Thanks much! You guys are awesome.

Thanks for the info. Is there some sort of regulator I can throw between the battery and the screen that will step the voltage down to 7.5v?

I'd like to make a fairly simple NES portable using the PSOne screen and NES board which would run off a 9.6v battery pack. A couple of questions, if you'd be so kind as to entertain them:

1. Can I run the 9.6v from the battery directly to the 7.5v in on the PSone screen or would I fry the screen ...
