Question Cant get composite video out

[jman124356]

This is my first ever build so sorry if this has happened before. I cant get my trim to output video. The cpu and GPU are heating up so it is turning on. I think the port could have been damaged while desoldering. I'm using 30 awg magnet wire twisted together. Does that seem to be the problem? Is there a work around?

I can see the connector pin outside the place , are you sure it's making good contact? see with the continuity with the tester, if you take the signal from the other side of the board, is 3.3v connected correctly u10 - gpu?

U10 is the usual suspect. Did you remove the caps by twisting them? if that's the case check the trace isn't broken. The composite trace should measure 75ohms to ground provided you didnt' remove the resistor just next to the AVE chip. If the trace is messed up, you'll have to wire it next to the ave chip.

The resistance is measuring 75ohms so I don't think it's the pad.

How would I check that "3.3v - gpu"?

test the point with tester when power on voltage on point

Thanks for the help it turned out to be a damaged port. I got it working by buying a broken wii for like $5 and harvesting the port

u can solder a normal rca cable without the port
