my dl4 still lights up .when bypassed it gives me sound however when i switch one of my presets on i get no sound. i only get sound when the unit is bypassed.

I did the reset thing to factroy default did the true bypass reset changed cables everything but am having no luck

line 6 help me please

Hello Sach,

I've registered my DL4 after reading this thread. Got exactly the same problem with mine. Haven't used it in a while. Have tried the factory reset already with the A-D switches. The leds are blinking when inserting the instrument cable. After that it's silent. In the beginning I heard nothing at all. But now I get the true bypass sound and can't get the effects to work. Switching with the footswitches doesn't work either. I tried turning all the knobs and a couple of factory resets. Power supply is a Line 6 MKA-091200GS, output 9V 1200mA. I read in another thread about 2000mA, maybe that has became the standard later? I own the box since 2001.

I hope there are some actions I can undertake myself in order to get the box working and am looking forward to your reply.

Greetings,

Guys I have the DL4 - had that same issue - get registered then search repair places for your area - apparently there is a power surge thing or something - they all do it eventually - or sooner than later - mine took 5 yrs - once fixed worked like a charm - was about $75 -$80 bucks - 2 weeks - ona another note - whenit was gone - my tone was horribal - the thing is magic - get it fixed - ps I have the M9 and they are NOT the same.
