Hello all, i have topping dx7 pro since 6 months, was working fine until today. it just stopped working, nothing shows in screen. however i still can see it in windows 10 but can not turn it on. Just feels dead, not getting hot as well. Fuse is fine not blow, anybody have/had this problem before or know to fix fix it up. thanks

Hopefully, your DX7 Pro still has a warranty on it, as likely a transformer blew, but the board is still working. That is probably why the unit will not turn on, but the DAC is still recognized by your computer with USB power still feeding.

it is still under warranty but will cost a bit to send it back to china. So i better try to fix before sending it back if it is possible fix

Okay...I was expecting a warranty question next...but ignore you had any other questions regarding its internal parts, post your question here:
