Repairable?

1. How about you post a model
2. How about you tell us what kind of voltage
3. Post a closer photo of the ride side of the board above the power connector

I dont see a replacable fuse which means your shit might be fucked.

I dont know the model nr.
And i guess it was 12V

This could be a very painstaking process with a good possibility that it may be beyond your capabilities.

If you can find technical documentation on the board with the specs of the simpler components (resistors, capacitors, etc) you could check that they're working as they should with a decent multimeter. Replacement parts for things like that are off-the-shelf stuff at a halfway decent hobby electronics store.

However if that doesn't find all the broken components and it's one or more of the surface mount chips that's at fault then the fix gets a whole lot more complicated and will be beyond the vast majority of people, including here on /g/. Not only is finding the broken part much harder, the replacement of a surface mount chip a royal pain in the ass if you're not used to do it.

Thus the simplest way to fix it and probably the only way you'll be able to manage is by finding a replacement board from another device that's been junked for being defective in another way.

You mean the dot at R82 right

also
start your diagnostic with the components near the power supply
