Screen going black temporarily when new graphics loadedI’m having an issue with an NES that I recently acquired, which I haven’t seen reported elsewhere. Periodically, the...
Resposta para "Screen going black temporarily when new graphics loaded"I found a roundabout solution, which was to buy an RF-to-coax adapter and plug the NES in through coax. Not ideal, as I’d really rather go through composite, but it suggests that either the problem on the NES was limited to the composite connections (and not something fundamental about the video processing) or that it was an issue with the TV. I suspect the latter. The TV may not have liked the signals it was getting through composite video, maybe the signal was too low-power to be detected as present. Or the TV and the NES were not syncing properly, like the TV was expecting a higher baud rate than the NES was providing, or the NES couldn’t get out all the new video information to the TV before the TV got tired of waiting and declared the connection lost. Something like that. I’d still welcome any thoughts, for curiosity reasons, but from a practical standpoint, I’m calling this one solved!
Resposta para "No Signal To TV"A flashing red light means that the system believes there is no game cartridge inserted. If there is actually no cartridge inserted, this is intentional, and not necessarily an indicator of a problem. If it’s still blinking when a game is inserted, the metal contacts on the game aren’t all correctly touching the matching contacts on the console’s 72-pin connector. Clean the cartridge with a q-tip and some rubbing alcohol, then try again, removing the game and re-inserting it multiple times if needed. If the red light still blinks, it means that 72-pin connector needs adjusting or replacement.
Resposta para "Yellow blobs on nes board acidentially removed."That sounds like flux to me. It’s used in conjunction with solder in order to make the soldering process easier. But once soldering is finished, it serves no purpose for the circuit, and should be removable without affecting anything. I suspect your display issues may be related to something else entirely. You could try re-melting the solder on those suspected pins to make sure they have proper connection to the board, Or it could be an issue with the new 72-pin connector.
