Hi everyone,
My TX happened issue. Now, when I turn on the Radio (blue LED is lighting), the LCD displays "shutting down" and "Power off" immediately.
Can anyone help me?
Thanks.

This sound to me like a power switch problem.
When the switch is on, there should be battery voltage on J6, pin 10 (ground is on pin 8).

Thanks, Mike
I have battery voltage on J6 at pin 10 (about 12V when I use the battery 3 cells) and the LCD is still lighting with display "POWER OFF".

Check pin 4 of J6, this should also have the battery voltage on it. It is the RF module power, switched from a separate contact on the power switch, and is used to detect the power switch is on.

I had similar problem and had to open and clean my radio's power switch.
