I tried a new cartridge connector and the games will now boot without pressing down but still scrambled graphics. A visual inspection shows the caps look alright but I don't have a way to test them. Thinking about getting a cap kit for it.

The motherboard for this TV looks almost identical to a NES-001 with differences in the video output area. Is there a chip that may have crapped out? How could I check?

• I have tested it with the RF cable (both channels) and composite video.
• I took the entire console apart and gave it a solid cleaning.
  • I noticed the lock-out chip had been disabled.
• I removed the 72-pin connector and boiled it.
• I bent the pins on the connector to ensure it would make contact with the game.
• While the 72-pin was off, I did additional cleaning on the part of the board the connector attaches to.
  • I also noticed that portions of the board that the 72-pin goes over had additional solder on it (clean, only on the single silver strip), I'm assuming to fix corrosion or something?
  • I used a multimeter on the part with solder to ensure connectivity to board.

Still after all the cleaning and boiling (and putting back together) it still doesn't load any game. I have an additional working NES, so I know the games do work for comparison. Everything looks good, but just have a solid white screen. Am I missing something?

I don't think this would damage the board, but the NES Carts have a label on the back that tell you not to do this so I am a bit hesitant to try it.

I have purchased NES from an online store and when I am playing games, it has some weird stairs effect, like every next line shifts with 1 pixel and then after 8, it goes back. On the letters/text it looks really bad. It is the same using Composite and NESRGB:

There are also weird yellowish shadows on the objects:

Any ideas about what it could be and what to try to figure it out?

Thanks!

Hi everyone, great little website and I’m hoping you can help me, bought a NES from eBay and turned it on (unofficial power lead) and it was flashing red. So I took the NES apart to replace the 72 pin connector, however since I did this the NES doesn’t power up. Not sure if I have shorted something. The power supply does work on my snes but I have bought an official one to try once it arrives. Any ideas what I should do next?

Just an update, I managed to fix the power issue with the NES. The lead felt flimsy in the jack so I inspected the jack itself and the large metal spring plate wasn’t in place so I gently bent it back up again and it worked!

Thanks for your help

I no longer get the Red Blinking Light, and I can get the NES to run both of my copies of Mario/Duck Hunt about 70% of the time, but I can't get any other games to work at all. And before you ask, yes I have cleaned the games, multiple times even. This is a second NES that I got basically for free that I am trying to fix and sell/gift. All of my games work on my personal NES.

I'm kind of just out of ideas at this point, and I'd prefer not to buy a new 72-Pin collector if I don't have to, but if there's nothing else I can try, then I'm open to doing that
