Hi,
Are the new Line 6 DL4 MM4 FM4 still repairable?
I have one defective DL4 and one defective MM4. They both have no power.
I replaced the 3.6 volts zener diode and C40, C48, C58 and C59 capacitors in the power supply.
All the supply voltages are good (6V, 3.3V, 6.6V and 5V) but the pedals still don't work.
I also tried a reset by holding switches 1 and 4 and by turning up the power but that did not help.
The chips are soldered directly on the board so it's not a socket issue.
I'm I missing something?
Nick
