1 FZ-10 weird lines across the screen
Like the title says, I have a Panasonic 3DO FZ-10 and when powered on it shows purple horizontal lines across the screen, the board looks fine and I’m trying to find a good starting place to check and see what’s wrong with this console, there is this chip that someone said was an rgb mod, maybe this could be the issue?
I know the power supply inside is a new one because the old one was burnt out when this unit arrived probably due to the wrong voltage so I got this replacement unit and it tests out okay
Update (11/05/2022)
I should also mention that I did try composite as well as S-video and they are both doing the same thing.
Cette question est-elle utile ?

@cwr take some good pictures of the whole board. The mod chip can most certainly be the issue here. What this looks like is a problem with the scan rate. Can you change your TV to something like the original 640x480 or 768x576 (unusual) and see if that changes things. If it is an RGB mod it should have a RGB board somewhere.

I had a 480p monitor from 20 years ago so I tried s video on that but same issue, I’ll upload pictures soon

@oldturkey03 I didn’t install this chip, I bought it from another seller and I asked him about it and he isn’t sure either, it looks aftermarket but I couldn’t find a good source online

@cwr i totally get it. Those are good consoles and I am all for it. Just hard to diagnose if something goes wrong. Good idea about using the older display. Nothing nicer than playing the games from decades ago on a retro platform ;-)

I uploaded the photos now, I did replace 3 caps near the video output just to eliminate that, composite and a-video both have the same issue
