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.
i was having some problems getting my 7.5v to the spot on the back of the mobo...i was wondering if there was a better or easier or just a different place to put in that wire...i tried putting it on pin 1 of the larger connectors but that didn't work...any ideas???
There are many places to put the 7.5v input. Follow pin 1 of the that connector (7.5v input) to the wire onto the external board that has the power plugin on it. It should be a blue wire.
this si an already taken apart screen and i only have the screen and main mobo...unless thats what your talking about...the pinout needs to be on the main mobo
On the bottom right of the back of the main PCB board, there is a voltage regulator (7805):
INSTEAD of taking a wire from the pin shown, take it from the pin on the far right of this picture. This is the input pin and SHOULD be 7.5v, check with a multi meter, and if it's 7.5v, put it there.
i think that that may work...seems obvious now...i think i also have a grounding problem because i am not getting 5v out of my reg...im getting like 1.3 i'll go over my wiring again and try to figure it out...
so i need to solder both the ground and the 7.5v to the same place??? and is that the ground from the batteries or w/e or is it the ground from the board??? thanks
A helpful little tip, Ground means Ground no matter what it is. So the ground for the board and the ground for the battery are exactly the same thing. All the grounds are connected.
im not sure if i am wiring something wrong but this still isn't working...is there ANYWHERE that i can place my 7.5v input besides pin 1 and on the back of the mobo...please help me...
Take your board, and arrange it so you're looking at the component above, in that manner. Now look straight below that. You'll find a small silver point that says 7.5v right next to it. Solder there.

Why can't you solder onto there? Just solder onto the furthermost right pin in that picture. OR, that arrow point right next to the mentioned pin, that arrow is pointing at a pin, solder to that.
ok thanks...i will try that tommrrow...i put everything away for tonight...thank you for the help...hopefully it works and i don't have a bigger problem on my hands
