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.
So I like solder the yellow to the yellow, white to white on the YOBO NES for video and audio.
I hooked up the screen and yobo, yobo turned on but the LCD starting buzzing, getting louder and louder, so I unplugged it as fast as I could.
So did I connect the two power jacks backwords or why would it buzz?
I mean, there is a piece that has 2 capacitors and a heatsink on it for the power wire, and it has 2 places that are EXACTLY the same for power into it, then out to LCD.
So should my LCD be fine? Did I just do that backwards?
Or does it always go buzzzzzz?
PS: No I did not turn the LCD on it just made the buzz being off.
Is there a voltage regulator board on there? When I hooked mine back up I found that quite a bit of voltage cleanup was done there, and my picture looked terrible without the regulator board. Also be careful hooking the connectors up to the reg board, as the polarity of the connectors is switched. Make sure the input voltage is going to the input on the regulator, and the output voltage is going to the red wire that goes to the screen.
