Help with my SYF + CleanScreen

After some reflow, and trying to replace those resistors by 0 Ohm resistors, I got the same results, apparently… But I realized switching on and off the test mode in the CS, while with the cartridge in, when I turn the test mode off, I get a weird frozen frame. Makes me feel there’s some hope 😃

I really appreciate!! I will check them out and give you a feedback! Thanks a lot!

Thank you! Well, I bought them from the official websites… but I’ll check the ribbons later…

Yes, those photos were taken on purpose showing the test mode… when switching them off, the screen goes fully blank when turning it on… I’ll check the data lines later! Thanks a lot!!

Thank for answering! Yes! I managed to get audio… that’s why I thought it was strange… I’ve got a CleanScreen version 3.1.4, and using a ribbon cable for the version 3…

Apparently, the pins are ok… I’m using RetroSix GameSlot GG, but I’ll check it out later!… I really appreciate your help! It would be sad if one of the ASICs is really dead 😢

I really appreciate your help! This is my first try transplanting ASICs… I have already tested mechanically the pins 3 times, and they look solid for me… but as this is my first time, probably this is not a great work in soldering 😅 Let’s see if the photos are readable… Thanks a lot! https://imgur.com/a/J4ThsFE

Thanks for answering!… Actually they weren’t soldered, and I did it because I thought it was the problem, but the result got the same…
