I've been looking for help regarding a top loader problem, but I haven't seen anything regarding this specific error. My NES top loader suddenly stopped working. When I turn it on now, it makes a quick buzz sound for 1/2 a second, then there are these large horizontal white lines that scroll up a black screen. This happens with all the games I've tested now, while the system had previously worked well for about 6 months.
Does this sound like a dirty connector issue, or could this be something else? I've tested this with two different RF connectors and 2 different power supplies. And I've tried cleaning everything with alcohol. I haven't opened the system up yet though. Any ideas? Thanks!
