I am learning to repair at least the power section of those motherboards. I think their power section has a generic structure. other sections of those motherboards contain expensive ICs which does not worth repairing. which sections of those motherboards do usually fail?

is there a generic diagram of a typical DVR motherboard circuit?

I dont have any DVR to repair now, but I am learning to repair their motherboards. Preferably, I need motherboard schematics belonging to one of the following models: HikVision DS-7104 HikVision DS-7204 HikVision DS-7208 HikVision DS-7304 HikVision DS-7308 or any similar models will be useful.

the motherboard schematics of any recent DVR model will be useful for repairing other recent models.

Dear all, does anyone have a diagram or schematic for motherboard of any HikVision DVR device that shows motherboard's circuit? thanks in advance.
