Hello all. Over the last while I have done a lot of work to this n64. I got it with no picture and after opening it up I noticed it had bulging caps and liquid damage. After replacing the rcp, power switch, cleaning the contacts and recapping the full board I have a working console.
After getting it working I realized that my upscaler only takes component and not composite so I tried to install an rgb mod from ali express. After finishing it up I can't get any component output from it. Although composite still works.
I can see 0.85 volts ac on the video pins and have ground and 5v power to the board. Unfortunately I don't have an ociliscope so I can't see if there is any actual signal. The board is a -03 with a VDC-NUS chip. I don't think I did anything wrong aside from some ugly solder joints going to the daughter board. Everything has continuity as well as no shorts. My board also has components for sync.
I feel like I'm losing my mind and have been beating my head against this for a while. Does anyone have any ideas?
Edit: memyfofum pointed out rgb and ypbpr are different signals. The mod is probably working fine and I just need to get a scart cable instead. My bad bois.
