Power my 4.3"Screen question

[MoRZiLLo]

Hi all! I'm testing my Gamecube portable 4.3" screen and works fine.

Put it on 5v from powerboard and run well sometimes, others, cause flickers and artifacts.

In the back of the screen says 9v~36v

My question is... How put 9v to my screen? or 7.4 with original powerboard?

I put 12v from my cube, but doesn't turn on. I believe that this screen runs off of 7.4 but i don't know how.

Can i put at same time 5v+1.9v? or +3.4v? Don't try because i can't fry other board. I'm low of money now.

Did you put 12V While the cube was on and connected? It will only turn on with a signal.

Yes i did, but i don't plan of put 12v in my cube.

I hooked up 12v~5v and runs but the problem again....

The thing that solve this is a tricky read in some post on megasticky(Tchay's or ShockSlayer... i don't know...).

Put double of wire and strong than others in GROUND at pin 1 of powerboard to the Gamecube Pin 1 GROUND.


That's ALL!!!! Runs well in 5v and got sound again

Thanks for the response Prog!!!
