Hi everyone,
My Benjolin is dead for some time now. It won't produce sounds using its knobs. If I touch the lower side of the board with my fingers it does react in some way, but the instrument really won't work the it is supposed to be working.
Could anyone guess why this is happening?

Greets,
Alex

dry joints? Some of the most common faults are due to bad soldering, or where a point has become dry over time. Also is your PSU connected the right way round?

Try prodding around where you have soldered, see if that does anything. When a voltage is supplied, are you getting anything at all at the line out?

Sorry Rob, for butting in too. Embarassed Very Happy

Bad solder joints are the cause of malfunction in hobbiest built electronics 90% of the time. Inspect all the solder joints and make sure you've got a solid connection. Reflow spots that you're not sure about. Get in there with a continuity tester to make sure youve got contact between leads and the board.
