WTB Zenith/PSOne board
Howdy. Well, after having a number of problems with the video on my screen, I finally did it. I messed up the connections between the ribbon cable connector and the rest of the board. The screen appears to be fine, but I need a new motherboard.

Re: Power Issues... (SOLVED!) But, now I get no picture.
Well, I finally got my screen isues to work. It appears I got a little crazy with the soldering iron and soldiered the 7805 to this piece of metal next to it. I cleaned up the solder. I then grounded the audio/video and it works. Pretty much.

Re: Power Issues... (SOLVED!) But, now I get no picture.
There isn't anything displayed on the screen when there isn't a video source. The brightness and volume levels display when you push the buttons.
Hmm. When I press the buttons, nothing happens. I guess that means my screen isn't actually turning on. Well, now that I know that, I'll see if I can ...

Re: Power Issues... (SOLVED!) But, now I get no picture.
Hmm. I'll check that.
I have a question for those who have used the Zenith screens. If I just power up the screen, without any video source, should I get any sort of picture? Such as color or words or anything? Would the Brightness and Volume Control buttons display anything on the screen?

Re: Power Issues...
I think you wired up the regulator wrong. Either that or it is "dropping out".
Good call. I had the regulator in backwards. Now, I can get the screen to power up, but there's no picture. I tried to connect a wire from the 12th pin on slot 1 to the 7805, but it still doesn't work.

Power Issues... But, now I get no picture. (SOLVED!)
Alright, I'm attempting to power my Zenith screen with a 9.6 Ni-Mh battery. I'm running it through an Adjustable Voltage Regulator, which then runs through two resistors (220 and 1.1k) and two capacitors (Using this schematic ). When I don't have the screen plugged in, the multimeter reads 7.6 volts ...

Re: Question about LEDs (Placement and Connection)
I'm assuming you meant "How do you mount the resistors"
Basically it doesn't really matter. Whatever is more convenient for you.
And both ways to connect the LEDs to the resistors will work. Just do whatever is best for your project.
Twisting the metal leads and dabbing it with solder will work ...

Question about LEDs (Placement and Connection)
Hi all. Long time lurker, first time poster. I'm still pretty new to this hobby, but I've learned a ton of stuff reading both Ben's book, as well as the posts on this forum. I think I'm ready to create my first portable (NES).
I, however, have a quick couple of questions about the LED backlight mod ...
