Question Image interference after cutting

[jannviruz]

Hello everyone, I'm making a new project with a k01 board and the problem is that when I turn on the image for the first time after having made the cut, has something like this happened to you? I went over the whole cut and I don't see any connection between tracks or any indication of this bad image, I got a little carried away with the dremel and I scraped a bit but I don't think it should affect it there, tell me if something similar happened to you and if you solved it, the video cable is about two meters long but I've used it other times and this didn't happen, I'll put up some images.

Hmmmmmmmmmmmmmmm. The nike swoosh is in a safe area, nothing important there for it to hit. That inside corner you've done in the trim gives me hives, but afaik in that spot the only problem it could cause would be a voltage short, and the system boots so that's not it................

How long is your composite wire? Is it shielded at all? Is the AVE and the area around it completely clean? If not, give it a good dust off and an IPA wipe down. You might have just enough conductive debris laying about to mess with the signal.

Well, the cable is about 2 meters long, I already used it for tests with other projects and nothing like this appeared, I will try with another shorter cable to see what appears and thus rule out the cable as a cause, the corner is the first time I do it so as not to lose that anchor

Hi, I'm having the same issue with my trimmed board. It's also a K01. I tested 3 different wires (yellow Composite, 30 gauge shielded and 32 shielded magnawire) and the issue persisted with all of them exactly the same. Then, I rewired all my voltage lines to de PMS (didn't work). Finally y decided to re-sand the edges of the board a little bit, but the issue remains.
What's really wierd is the following: When I turn on the wii, the tv screen goes black, next, it looses the signal, and when I touch with my bare finger the board processor or any voltage soldered pin, the image returns to the interference video image. What could it be going wrong? I thought maybe this issue is just for the testing and, when soldering the VGA lines, it will be solved because it's another type of video output, but I'm also worryed that it could be some kind of ground loop or voltage short...

Got it! I was right, the interference goes away once you connect to the VGA.

Got it! I was right, the interference goes away once you connect to the VGA.

My problem was that the cable was too long and that's why it was causing interference. I tried a shorter one and it was fine.
