pncola Posted July 19, 2017 Share Posted July 19, 2017 Hi. I bought a pre owned HD400 last month and I don't have too much knowledge about line 6 product. My HD400 takes about 2, 3 minutes warm up time to come out the full sound after turn on. After that it works fine. No need to wait again for the warm up if I turn off and turn on again. Is it common for every HD400 to wait 2, 3 minutes at the first time power on. Or is it error? Please advise. Thanks. 1 1 Quote Link to comment Share on other sites More sharing options...
elcosomalo Posted July 26, 2017 Share Posted July 26, 2017 I´m having the same issue.. I have tu hit the strings really hard to make the hd 400 sound, and the sound is crackling. After a that, some minutes later the guitar starts to sound but the sound is muffled and changes over time while playing... like when applying a really strong noise gate (which I disabled for all my patches). I think it is an electronic issue... like a capacitor dying. I opened the thing but I could not see any dead caps (visual inspection only). I think it is a capacitor because over time the pod seems to go back to normal like if "something has charged up". No clues... :( :blink: Quote Link to comment Share on other sites More sharing options...

julious_frost Posted September 12, 2019 Share Posted September 12, 2019 Any solution for this ? Quote Link to comment Share on other sites More sharing options...
Davo1 Posted March 30, 2020 Share Posted March 30, 2020 Yeah, any suggestions from tech support would be appreciated on this (POD HD400). I'm up to about 15 min wait before getting any real sound to happen. The unit never goes anywhere, just stays in my house. Giving it to an electronic repairer to "go find the problem" is a very expensive route, and if I had to do that then this brand is dead to me. A real shame a crappy bit of electronics is ruining the experience, because the rest of the unit is very robust. Quote Link to comment Share on other sites More sharing options...
joel_brown Posted March 30, 2020 Share Posted March 30, 2020 Sounds like a capacitor going bad. A Line6 authorized repair facility may be your only choice but it may end up costing what you paid for it. When I had my PODHD repaired a few years ago it cost $75 to fix it but back then the PODHD was $500 so it was worth it. Quote Link to comment Share on other sites More sharing options...
