Did it work ever before? Which firmware is installed - stock Walkera or Deviation? If second: which version?

Just to find out little more could you try connecting usb lead then power Tx while hold 'Ent' key, so can see if deviation is running it should show Flash drive.

If you press 'EXT' button, power on Tx and see nothing at Tx screen, then it's the hardware problem.

That's unfortunate.
Lets start with detailed picture of the internals. And hope you have a multi meter.
Oh did you use lipos to power Tx and 2 or 3s if so?

Could you verify the main switch as I wrote to you in PM?

You will have to measure the voltages in the power circuit to check if there is something wrong:
