Hey guys! I recently bought a broken NES and replaced the 72 pin connector, and it worked great! until I removed what I thought was old soda from some pins near the RF chip, turns out I messed up, and my NES shows a monochrome screen for a split second, then goes to black while still playing audio. Does anyone know what the substance is so i can find a replacement and put it back on my board, Thanks!
