Screen going black temporarily when new graphics loaded
I’m having an issue with an NES that I recently acquired, which I haven’t seen reported elsewhere. Periodically, the screen will go black for about 2-3 s. This always happens when there are lots of new graphics being loaded in. For example, in Final Fantasy, it happens when I go from the world map to a battle screen. In Bubble Bobble, where each level is one screen, it happens at the start of every new level, starting with level 3. And in Kirby’s Adventure, it happens any time Kirby moves enough to cause scrolling. Oddly, while the majority of games I’ve tried have this issue, it’s not universal. Mario 1, for instance, never does it, no matter how fast I force the screen to scroll. Maybe its graphics are simpler to load? In any case, I doubt it’s an issue with the game cartridges.
This console has had issues with the 72-pin connector, which I have improved, but am still working on perfecting, so that’s a possible source.
I’m connected to a Toshiba flatscreen smart TV (50LF711C20) via composite (RCA). No other device that I’ve connected to the TV has had this issue, including a DVD going over composite. I have tried swapping out the video cable, which had no effect. I have ensured that the Picture settings for Composite specify “Game” mode. I unfortunately don’t have another TV with Composite that I can try out.
Could this be some faulty video processor, or a memory chip not loading the data fast enough? Or a fundamental incompatibility between the NES and this TV? Or should I just keep fiddling with the 72-pin connector, since it’s generally the Root of All Evil?
Any thoughts are appreciated!
EDIT: Boiling the 72-pin connector, while generally seeming to improve connectivity, has not resolved this specific issue.
