TK1 board is not turned on. Could you help me?

Hello.

I have a TK1 board and a TX2 board.
I have known that power supply of TX2 is 19V and above 16V may damage on a TK1 board.
I connected a TX2 power cable to TK1 board by mistake because it looks very similar.
In less than one second, I knew my mistake by a loose connection, and I disconnected that cable.
However, after that when I push the power button than a fan and a light turn on a second and turn off immediately. TK1 is not turned on now.
How can I repair my TK1 board?

Best regards,
