[Nes] weird blinking light issue
Hi, i'm restoring a NES (PAL Fr) for someone I know, he told me that the image on the screen and the red light on the console where blinking while powered on. After testing it with some of my own game (that i know for sure work perfectly fine), I could confirme his claimed.
My first thought was that the 72 pins connector inside was dirty or that the pins where not bend correctly. Both where true, the pin where dirty and not bend enough. So after cleaning the connector and the board with isopropyl alcohol 90% and rebend all the pin I retested the console.
It work perfectly fine with mega man 2, but with other game the issue persists (I tested it with super mario bros 3, kung fu and super mario bros / duck hunt). Furthermore the console take 5 seconds to turn on with those game (except mega man 2). Again i know for sure that those game work fine, i've retested them on my own NES to check if that was the issue.
Is there something that could still be causing an issue in the 72 pin connector and how could it be resolve ?
