Hello. Please I connect 9 volt power supply, on tone board with y cable, and I think break some component on circuit.
Can help me to determinat what component I need to change on mother board ?
Hello, That is unfortunate.
If yours is the Tone1, the original TB, the schematic and silk can be found here.
If it is the Tone2 Pro, the schematic is not yet available, not sure if it will be.
In either case, depending on your electronics knowledge and repair skills, sending the board back to Khadas might provide the best result.
Good luck. Keep us posted.
Hi, first, check and change the cables everything, check the voltage supply.
