Hello Mr. Ichikawa

A little hint about extension cables - if you are simply soldering flexible wires to the circuit board, use a hot glue gun to glue the wires to the board. That way the wires can't flex and break next to the board. The glue can be cut away if the circuit board needs repair in the wiring area.

It worked owing to it.
Cause:
Disconnection in extended cable.
Voltage was measured only on the main board, but it was not measured on the display side.
I was thinking too much that I could not understand simple things.
If you write here, you can become cool. It is very important to change your mood.
Many thanks.
