I know it is old but it's all I could afford. I just got a Portastudio DP-01FX/CD and all seems to work, that I have figured out yet, except track 4 will not arm or record. LED will not light and no matter what I do no signal goes to the level meter. Thought the LED might be dead, but I don't think so, and I tried to clean the switch from above an that did nothing. I cleaned the slides and the front switches and volume pots and that seems to have cleaned up the sound but I have not taken the main board out. I am lost on this. Any suggestions would be appreciated. I dread removing the main board...
