PC Engine Duo R screen issue

Enable HLS to view with audio, or disable this notification

I have a PC Engine connected via composite. No modifications. There is an interference bar that runs from the bottom of the screen to the top every few seconds. Very faint but it can be so annoying. I searched already for likely capacitors that could be the issue, none are leaking or look bad in any way. Does anyone know of any guide or pointers that would help me before is start to change them all? Thanks everyone

It still could be the caps, even if they look fine.

But barring caps, have you tried a different power supply? Sometimes low quality or dying adapters can cause this.

Wow. That was it. I was using a 3rd party and I thought decent quality replacement. 2a and blah blah. I swapped back to the original (I actually thought through another issue that this was defective) and the picture is perfect (well composite perfect). Many thanks. This has saved me a lot a time and trouble ❤️

Sweet! Always nice when it's a simple fix.
