This happened to me back in 12/2020 with low output on left 1/4" out. Fixed by Long and McQuade in Vancouver.
On my invoice:
Confirmed low/no output of left 1/4" output. Left XLR ok.
Traced problem to Q14 and D50 mute circuit.
Replaced Q14 and D50. Test OK..
Did factory reset. Went back to 2.91 and 2.82 and 2.81 but no luck. Checked all cables.
Right 1/4", both XLR and all loop outs are working fine. Left 1/4 out very low volume.
Line6 already said to take it to a repair depot.
Helix floor.Left 1/4" out is very low in volume and all other outputs are fine. Not in warranty but needs to go in for repairs.
Not asking what my repair would cost as we don't know whats broken.
Just wanted to know what other problems that people had and what the cost was for the repair.
Helix floor 2.92. Just started today my left 1/4" output is really really quite. The right 1/4" out is OK.
XLR and loop outputs are working fine. Did factory reset and it's still the same.
Anybody had this and got it fixed?
My up button did that too. I sprayed it with some contact cleaner and it was fix ( for now). You have to open up the unit to get at the switch.
Will have to change the switch in the future.
