Hi, i've experienced this very weird problem with my line6 dt50 212 that i just bought about a week ago.

After 15-30 minutes of playing with the amp, it will suddenly make a (very) loud crackling and popping sound and then my guitar sound wouldn't come out from it.

However, after turning the amp off for 10 minutes, it will become normal until the loud crackling noise appear again.

When the dt50 is working normally, the tone is excellent, I don't have any problem at all with sound quality. Nevertheless, it is very annoying to stop playing every 15-30 minutes or so.

Does anyone here perhaps have had the same problem and can give me a suggestion ?
