White lines/noise all over the screen? (GameCube)

[Hugo_Peters]

Hello modders!
I recently got my new mobo, and after a lot of testing and stuff I hooked it up to my TV (not a PS1 Screen, because I'm not getting
any signal at all on it )
So when I hooked it up I got only a weird noise on the screen and some fast scrolling lines.

I switched ground twice on the PAL AV Board but nothing helps...

Can anyone help me?

man you sure arent havin luck with these motherboards

Okay.

1. Check all voltages. Make sure they are what they need to be, make sure theres no bridging going on.

2. Always try to test everything before you wire anything up. Was the board working before you made modifications???

3. The AV cord can be confusing sometimes. It actually took me a good half hour just to wire the board properly using the AV cord because of grounding issues.

4. Check your grounding wires. Check them again.

5. Take off the DD and any other extensions. Simplify the board to try to highlight the problem

***6. Play around with the ground and AV WHILE the board is turned on. Then you can see what makes a difference on the screen. This has helped me when I was in a pinch.

6. Place motherboard into microwave and turn on for 15 minutes. Then buy a new one.

I find it's best to skip straight to step 6.

1. Check!

2. Yes!

3. I'll do some Re-Wiring and experimenting

4. Okay!

5. Already done!

6. I'll see if that helps! Good idea btw!

6. I already demolished the IBM processor from one of my broken Mobo's... See my avatar.

Thanks for the help again Tchay!
