Phone not powering on

Hi,

I was on a call and all of a sudden my phone switched off and it is not powering on now.

I checked with the technician and they told that the board and the battery is fine. I tried booting into recovery or into downloading mode and it does not happen.

Wondering how to make it power on again. Pls do help.

Regards
