    Why AlphaTheta DJ Equipment does not turn on?
    • T
      Thomas JonesAug 5, 2025
      If your AlphaTheta DJ Equipment doesn't turn on and the MIDI START/STOP (WAKE UP) LED isn't flashing, it could be due to several power-related issues such as SW power defect or wire defect. You should check for the V+12E, V+5E, and V+3R3E power. It may also be due to a RESET signal abnormality, in which case you should check for the PNL1_XRST signal. Another potential cause is a 16 MHz CLK abnormality, so check for the 16M_CLK (3.3 V 16 MHz) signal. Lastly, a PNL1 UCOM defect could be the reason; in that case, check the soldering status and replace if necessary.
