By mistake I've connected my camera to 12vdc
. Now it desn't start up. When I connect supply the blue led only lights and nothing more. Do You think that it is chance to repair it? Can be damaged transistor, chipset?

... the best is to check the board. I don't think the power from the charger feeds directly the dashcam, so there should be another DC-DC converter somewhere on the board. If you're lucky you fried only this part.Do You think that it is chance to repair it? Can be damaged transistor, chipset?
No one said it's a switched mode converter.Definitely not a DC/DC - if then a linear regulator.
Do you have any datasheet information (e.g., input voltage ranges) ?The supply is most likely directly connected to the A7. Applying 12V to that will fry it. I have very little hope unless you're willing to replace the A7. It's made in a 32nm CMOS process, which is known not to be happy at all about unintentional 12V
I'm not expecting that; my question is about: "how much" ?It won't take 12v
then it's also known what are the input voltage ranges ......known not to be happy at all about unintentional 12V
Some data:1.8v or 3v
