Q:
Hi, I have a problem. When i Turn the tuner, the LCD just Blink.
How can i solve it?
A:
The power-on failure may be caused by low battery charge.
Connect the USB cable and see if it powers on normally.
If it does, it indicates a power supply issue. In this case, after charging for 30 minutes, unplug the USB cable and see if the ATU powers on normally. If it does, continue charging for another 4 hours.
If the ATU still powers on normally after unplugging the USB cable after charging for 30 minutes, and only works properly when the USB cable is connected, there may be a problem with the TP5400 battery management chip or the battery. We will continue to discuss this.
Q:
I did all the tests. Still not working. It's connected to USB power supply and just Blink.
A:
USB cable or charging adapter problem
This can only be caused by a power problem. It's likely that your charger or charging cable is faulty, preventing charging. Low battery is causing the device to boot up.
Replace a different USB data cable and charger.
Do not use a fast charging adapter or a Type-C-Type-C cable.The ATU's Type-C port is faulty, preventing charging.
If the device still doesn't work properly even with a USB cable connected, it could be a problem with the ATU's Type-C port. To do this, open the ATU (first remove the front panel, then the back panel) and check for a poorly soldered connection.
