Grinllord Posted December 22, 2020 Share Posted December 22, 2020 Does anyone know where I'm going wrong with improving my NES? I've owned it since new but it's been in storage for 15 years until recently. Some of the games worked but intermittently. The first thing I did was cut the pin to the NES10 chip which worked. Then I manually bent the pins on the cartridge connector for a tighter grip and sprayed some WD40 branded electrical contact cleaner on the cartridges. This helped a bit. Then I removed the 72 pin connector and boiled it as recommended elsewhere, and cleaned the motherboard connector with a fibre pen, then wiped it with nail varnish remover and cotton buds. Since then it hasn't loaded a single game. Just a grey screen. I bought a new 72 pin connector, and cleaned every cartridge with the nail varnish remover and cotton buds, but still no joy. I'm wondering if I've left deposits on the motherboard or cartridge connectors with the fluids I'm using? The WD40 contact cleaner does say it's non-conductive, but that's why I used the nail varnish remover to clean afterwards. I have alcohol cleaner as well but I haven't used that yet. Considering flowing some solder onto the motherboard pins, and then running desolder braid over it to keep the solder area small and flat. Any other ideas?
