UP Square burnt, how to repair?

fantuan

Hallo, everyone,
I wrongly pluged a power adapter(19v, 3.42A) to UP Square for about 5 seconds. Then I smell something like plastic burning. Now I tried it with 5v adapter, board can't start and there is no light near power button.

In this discussion"https://forum.up-community.org/discussion/comment/7897#Comment_7897" Troy Lin said: "UP2 and UP-core has OCP so it will not get burnt like the UP board." So does it mean just OCP will be burnt? Where is this component and How can I repair the UP Square?

Thanks.

@fantuan I am afraid it is a way of no-return if you plug a wrong voltage power input. We do put power protection on UP Squared circuit, but it can not protect so wide range wrong power input.

@Aling Oh, it is a bad news. Thanks for your reply.
