N64 wont show video ( But sound works?) Any Suggestions?
Topic Started: Apr 4 2018, 09:34 AM (188 Views)
Greetings all,
New to the forum. Long time gamer, collector and enthusiast .
I recently got a N64 from an attic, has been sitting for about 8 years.
I disassembled it as it was very dusty. Found that the N64 was built in 1999 judging by the ID tag under the game Pin connector.
I took it apart and cleaned all the connections with Iso Alcohol. Surprisingly the board and fittings looked good. I re-soldered the Power connection, and Multi AV port connections to make sure the unit has fresh solder to complete the electrical connections.
Now i got the unit to power on, and I have sound but NO picture? Any idea why ?
Also i have another N64 in good working order, that I have hooked up the the same power supply and cables and it works perfect so i know its not the power brick or cables.
Is there a certain section of the N64 board i can jump out / or re-solder to test for picture?

*Some added info. The N64 power brick and Multi AV cables are genuine Nintendo, I use these on my currently working N64.
Also I have them plugged in to Sharp 27" CRT tv.

To be clear, the system had no power when you pulled it out of the attic. Now you have power and no video correct?

Here's a pinout for the AV Port to board. https://moddedbybacteria.files.wordpress.com/2009/12/supporting-pic-2.jpg

I'd take some electrical contact cleaner, spray it into the AV Plug, and then plug and replug into the port a few times. It should dry pretty quickly then see what you have.

I'm just thinking there's still some dirt or dust keeping you from a good connection.

I'll try this when I get home. Hopefully that is it. I'll also try to resolder the video post connection too too see if it has good connections.
