Baby monitor camera power isuue

I have a Motorola mbp36s baby monitor camera which was working fine until the power cable got damaged and it shorted out when moved when plugged in. I tried a know working cable with the correct plug top transformer still not working. I took the camera apart and tested the power in to the switch then out the switch and found a zener diode seemed to have gone. I replaced this and now have 5v on it. But still not working. I would like to test further with the test points on the board but not sure what I'm meant to be getting on them.

I can't find anything on line like circuit diagrams or what the test points are meant to read. Can anyone help please?
