Please I have a sonic port. Yesterday i connected a guitar via aux(1/8 plug) in because i didn't have a cable with 1/4 plug. Sonic port fell down from a table on side the side where the cables are connected. I found out that the jack has developed a fault (loose soldering joint, i think). When i connect the aux -in cable, it doesn't work; i have to exert small pressure before signal can travel from the guitar to the sonic port. i think some soldered joints on the jack have broken. I have background in basic soldering and electronics so wanted to fix it myself. I tried to open sonic port to fix the soldering but it would not open. I'm in Ghana and shipping to Line 6 for this small fix would be meaningless. Please help me.
