SNES Vertial Lines Issue

[jamescurtis24]

Did you try another TV?

Yes, same issue. And again, exclusive only to this system.

What you are describing is not possible. The standard SNES AV cable has one input for visual and 2 for audio - regardless of what your TV inputs do, it isn't converting an audio signal from your SNES into Video signals. Unless everything I know about audio / visual is wrong

Modern TV's use the Luminance port on the component connection for a composite video port. He's using composite, but since his TV lacks composite ports, he's using the luminance port on the component inputs.

I've run into some graphic problems using this on some older systems. Agreed with everyone else that you should attempt to run it on a different TV first.

If cleaning the cart slot doesn't work, my guess would be PPU as well. But isn't that surface mounted? Quite a bit beyond basic soldering skills (and tools).

It has been tested on another TV, and the same issue occurs. And I used regular AV ports on that one

Are these of any use?

If it is having the same issue on another tv after cleaning then your PPU is most likely the problem. I would start with replacing all of the 100uf the capacitors first.

Is there a tutorial for that?

This should get you started:

Would it make a difference that it's PAL and mine is NTSC SNS - CPU - GPM-02 ?

I'm thinking I'm just gonna have to source this repair out because I've never soldered (sp?) before in my life and have no understanding of how that stuff works.

So the connection is still composite. Interesting nonetheless.

Oh, and

If I am not mistaken, the main pcb is the same regardless of region.

Honestly, it will be cheaper to just buy a new SNES. Sorry.
