My Beloved Canon 70D is dead... Or is it

So iv had the canon 70D for about 2.5 years and on Christmas morning it froze gave me a err 80 code and wont power back up. So its been a few days and keep trying the camera, put the battery in and nothing. Today I put my 18-135mm STM lens on the camera and I noticed that the view finder got when the battery was installed. I also noticed that with the camera was switch on I was able to manual focus the lens. The STM lens is servo driven so you shouldn't be able to focuses if it was not getting power.

After the camera first quit I did some looking at it looks like the main PCB board is fried from what other people with the same issues have said. It would be a $450 fix so almost as much as guying another used body.

So i would love to hear you guys thoughts on the issue and if anyone has had the same issue.

If I can't get this body fixed I will probably upgrade to the 5D mark iv so I might open up the 70d and see if I can see any issue where the PCB might have been getting hot or something like that. I work at a place where we build some PCBs and stuff like that so some of my coworkers know a bit about electrical engineering so maybe they can find something.

Anyway im very sad either way and need to figure out something I feel so wrong being without a DSLR.

The trick is figuring out what goes bad, easiest to find somebody who has figured out the common failure points already, then it's just swapping out the tiny blown component(s) which takes some skill and equipment that it seems you can farm out for cheap.

Ya luckily my work has some really nice stuff and tons of resistors ect for printed circuits.

Just really stinks that a camera that is said to last to 100K shots only lasted to about 25k.

I would find a Canon-specific forum and ask there. Seems like there should be hope for a solution.

Ya iv posted up a few places about it but nothing yet. I know how hard we were on the 60D and they were great wish the 70d was as reliable.
