The problem of damage to the motherboard of Canon SLR camera

The motherboard is broken? Generally, a camera has three motherboards: the power motherboard, the digital processing motherboard and the mechanical transmission motherboard (which is how Nikon divides it). Generally, the price of a board is above that of 800 yuan. If the damage is too great (for example, all three boards have to be replaced), I suggest buying another one (for example, the price of second-hand 1000d is 2000 yuan, and the price of the corpse is unknown). As for the possibility of outsourcing boards, these parts are not universal and it is difficult to buy them outside. If you have friends in the photography circle, try another way. (For example, supplement internal invoices)
