My wife's Canon 5D MkII seems to be bricked, and I'm looking for input on what the issues might be and if it's reparable (or worth it to repair it).
The first thing that happened was, when taking a photo, the shutter actuation would take a few (3ish?) seconds no matter what shutter speed was set on the camera, and the LCD screen would show an Error 70. She tried a number of different solutions found online which involved resetting the camera in various ways, including removing batteries and draining power completely and using/formatting different SD cards. The only thing that worked was using rubbing alcohol and q-tips to clean the camera's sensors which connect to the SD card.
This solved the problem for a couple days, but when the same thing started happening again, other issues started popping up. She started getting Error 06 message in addition to the Error 70 (which apparently means the camera can't detect the sensor when it's cleaning). The shutter actuation now takes 5 to 10 seconds, regardless of the set shutter speed, which probably means the sensor isn't detecting the amount of light bouncing off of it. The LCD screen went out, it's only showing images that look like this
. These problems accumulated and all are occurring simultaneously now.
We can't seem to find this combination of errors online to tie it to a definitive problem, but this all seems to point to a main hardware problem, such as the motherboard or the sensor going out. The camera is 5 years old, and she estimates the number of shutter actuations at 120,000 to 150,000. It's about 5 years old at this point, and well out of warranty. If it was in proper working condition, it would be worth about $1200 (based on keh.com and other similar price comparisons). She's debating whether to get it repaired or not - i.e. send it in to Canon, who would tell her what's wrong with it and give her an estimate to fix it. She shoots weddings and other paid gigs on the side, so she's buying a new replacement (apparently they just recently stopped making the MkII, so she's getting a MkIII) but is debating whether it would be worth it to fix this MkII and keep as a backup body.
Can anyone shed any more light on what's probably wrong with it?
