Broken Ulanzi TC-001?

There are some known issues regarding the voltage regulator of the 2023 March batch of Ulanzi TC-001 clocks. It appears that the LDO voltage regulator may be defective and if it burns out, may need replacing.

When the screen is frozen, you will be able to turn off the clock by pressing the left and right buttons simultaneously but you will not be able to boot it up again.

Your best bet is to contact the seller or Ulanzi directly for a replacement unit.

But some folks over at the Awtrix github forum and Discord say the regulator can be replaced with a STI3408B.

Here as an imgur gallery which may help in taking apart your Ulanzi TC-001.

Use this hint at your own risk

Good luck!
