It was continuous rebooting in recent days and finally power off and now it does not power on.
I checked the circuits, there is no physical damage.
what could be the problem?
 
IIRC those still had a LiPo battery. Was it shutting down correctly (no corrupt last file) before the looping started? It could also be a bad sd card. Use 'sdformatter' then run a full overwrite with 'h2testw' to confirm the card is good.

It has capacitor I bought from GB.
It isn't power on with or without sd card.
While rebooting It seemed as though not enough power.
 
Have you tried a different power source and cable?

If it still doesn't turn on. One thing you can try is to leave the unit alone for a few days and then try powering it up. Something about letting the capacitor drain completely.
 
Test it in the house using a phone charger. That will eliminate the PS being the source of the problem.

Thanks for replies
I tried diffent power source and I will wait a few days and keep trying.
Edit: There is no change in the camera.
I think the cause of the malfunction is due to low voltage.
