I recently decided to finally get my hands on a Sega Saturn, a JP model 1 to be exact, I paid 100$ for a bundle which came with the unit, cables, controller and JP Panzer Dragoon game, but upon booting it up I was somewhat disappointed to see that it has noticeable Horizontal Scanlines that flicker throughout the screen. Now I have tried it on two CRT's via AV cables, and even tried a different power cable. It isn't completely terrible during gameplay, but during darker scenes it's a lot more noticeable and just an annoyance overall.
After doing some searching it seems to be a problem in the PSU department, and would unfortunately more than likely require some replacement parts and soldering. I could probably repair it myself, but am honestly a bit hesitant to do so.
Fortunately the seller i ordered from has a free return policy, but I'm unsure If I should go ahead and return it or not. I wonder if this Is just a super common thing? did I just get unlucky?, or should i have potentially got a model 2?
I'm a bit torn, and any advice would greatly be appreciated.
It's caused by aging electrolytic capacitors in the system (particularly around the PLL), and/or old EMI filters on the video output lines. An old power supply can also cause it, but then the system would make an awful noise and wouldn't boot anything.
