BRZ 1700.1d

hi all
This amp came in with one shorted output.I remove all the outputs from the board.
I have both - + reg and rail voltage.some one did some work on this amp before i got it.I want to find out on what settings should i put my scope on to take some test on the
output pads to make sure everything is ok .Also what wave form should i see on them.
(Learning to used scope tektronix 2215A

pic1 is the first leg on my PS FETs (5v div 10vus
pic 2 center leg (5v div 10us
Do they look ok for this amp?

Ok scope is now set at 10v/div 10us/div
first pic is gate of the PS FET
second pic the the center leg
third pic is pin 10 and 9 of the pwm IC
what point can i test with the scope to know if the output section is ok?
I replace all output FETs and drivers.Amp is playing good audio.
