In my opinion, You need to get that working in order to find out if there is any other damage, unless you own an oscilloscope. :)
Do you have a trainer cable ( 3.5mm jack plug to 3.5mm jack plug)? With that (instead of the oscilloscope ;) ) you could test if the radio is outputting a PPM signal to the module. It already did happen that removing/inserting the module with the radio ON, damaged the processor pin that outputs that signal. Some people were lucky though..
But another little test, when you turn the radio off, does it wait a second or two before it turns off, displaying "shutting down", or does it turn off immediately as soon as you turn the power switch off?

Cool!!!!order done,
I don't have oscilloscope but I do have the trainer cable and is working on the PC, so ppm signal good, right?.
An the other test , when I turn the radio off t does wait a sec or two displaying the "shutting down"

Not quite, the PPM signal that goes to the trainer port comes from a different pin. I will describe a test you can do to test the module PPM pin with the trainer cable.

Yes, that is good. :)

For testing the PPM signal in the module bay:

Go to the Radio Setup/Trainer menu and Program a trainer profile with "Jack" as source, as if you were receiving PPM from a Slave (student) radio. Turn the radio OFF.
You will need to use pin 1 of the module bay, so please isolate the other pins so you do not do any short circuit while testing on Pin 1. this is important. at least isolate pins 2 and 3. a piece of thin shrink tube around each of them is ok.
If you have a servo cable, you can also connect it to pin one and bring its connection outside the radio. Like that you don't touch the other pins by mistake.

Ok, after you done that (don't skip it) you need to turn the radio ON.
Then plug the trainer cable to the trainer port.
Now touch the tip of the other jack plug to PIN 1 of the module bay.

Go to the trainer menu.
While touching the tip of the jack plug on pin one, do the numbers of at the bottom of the trainer menu change when you move the sticks??
I will post a picture or two of how I would connect the jack to pin 1.
