I just removed all the screws and pushed the amp. The volume knob also has a screw. Just take it out.

Is it this screw that you referring to right?

Hi again, my DAC suddenly unable to hear sound, can only hear the statics and the LED is kept changing colors. Wanna know is it because of battery that cause this issue? Currently still haven't change the battery yet.

Hi everyone,

I recently replaced the battery in my Cypher Labs Theorem 720, and it's now working perfectly. For those who own this DAC, if you notice the LED light changing colors when the unit is plugged in and powered on, it could indicate a dead battery causing power issues. This was the case for me, though the cause might vary for others. I wanted to share my experience in case it helps anyone facing a similar issue.

A big thanks to the community for the support, and a special shout-out to @fishda30 for the help!

Nice to know that your unit is now working. My unit ran warm and dained its battery quickly prior to having the battery replaced.

When running properly, this amp is a champ. Great overall sound.
