Hi, I recently purchased a Line 6 DL4 pedal. It worked fine when I got it. Played with it for a few hours with the batteries provided (I didn't know that I had to purchase a different power supply for it). So I turn the pedal off, go to bed and the next morning the pedal won't turn on! It didn't suffer any physical damage, I didn't even mess around with the parameters too much. I did not try to fit in another adapter, again no physical damage on the power input. I have tried new batteries, purchased the Line6 Power Supply, didn't work. I have read other people's posts but I've never encountered one that happened to someone this quickly. I am not very good at repairing stuff, I will probably end up making the problem worse if I try to. I have tried resetting the pedal, didn't help. So I just wanted to post and receive opinions from experienced people in case I'm doing/did a really stupid thing or missing something. It's probably a faulty product, I would appreciate any kind of help before I return the product. Thanks.
