There is no video on any channel. What area on the circuit board should i be checking (for camera input #2) for damage when the cause of it not working was due to input connections touching from a spliced cable. I'm sure that's the cause because i blew each camera input one by one and the camera is still working. The jpg files is what i have and the model 22MS605R, in the pdf, is a similar but newer model than mine. The only difference is my slave output is rca instead of LAN connection and i don't have an alarm like the pdf model
