Have blue power light, no HDMI, no ethernet status lights

I've used up the board to make ROV. At first, it was working normally, able to ping between ground control and the vehicle that uses intel up board but after I will bring it out to improve the code by I have plugged the screen through HDMI to check the code easily, but it shows no signal but normally it can be done. And when I try to ping to find the board, the board doesn't reply. I tried checking the USB by plugging in the mouse but no power to my mouse, no ethernet status lights, But the blue power light comes on fan spins.
I tried following this link
https://forum.up-community.org/discussion/908/fix-wont-boot-no-hdmi
but nothing changed.
Does anyone know what is causing this or is there a way to fix it? I'm sure no water gets into this board. I have tested it many times, no problem. But there was a problem in this round that made it impossible to continue the work.
