I have a picture now but it looks horrible. It's very dark (I wasn't able to buy any capacitors yet because the store is closed) and it looks as if my screen is underwater. The image moves constantly like this:
/ / / / / / / / / / / / / /
\ \ \ \ \ \ \ \ \ \ \ \ \ \
/ / / / / / / / / / / / / /
\ \ \ \ \ \ \ \ \ \ \ \ \ \
/ / / / / / / / / / / / / /
\ \ \ \ \ \ \ \ \ \ \ \ \ \
/ / / / / / / / / / / / / /
\ \ \ \ \ \ \ \ \ \ \ \ \ \
/ / / / / / / / / / / / / /
\ \ \ \ \ \ \ \ \ \ \ \ \ \
/ / / / / / / / / / / / / /
Please help me! :(

It is currently using the AC adapter (the Genesis) though my screen is using a lower voltage adapter it has to be 7,2V but mine only is 5V. Could that be it?
EDIT: Also I'm using both my screen and my TV. That's not the problem because I already disconnected my TV but the picture was still bad. The problem is though: if I connect the screen GND to the Genesis GND my TV does not output any sound... Weird huh?

It works perfectly on my tv (with the original cable). But it is wavy on my psone screen (with soldered wires). I already checked the connections though and there seems to be no problem.

I'm going to try it right now!
EDIT: It works! Thank you so much :D ! The sony adaptor I had was outputting 7,11 V, but when I turned on my screen it went down to 5,31V. It doesnt have enough current I think. I used my special adapter which has 5 output voltages with a switch on it. I put it on 7,5V and it worked! Just one more question: will the image become at its best when I use the capacitors because it is still dark.
