set your multimeter to AC and test that you have voltage on the 2 ac leads on the bridge.
then set your multimeter to DC and then check the + -  leads on the bridge.

also make sure you have soldered both sides of the pcb to the legs on the bridge in case the solder throughs have been damaged.
make sure that the bridge is polarised correctly (I.E. the 2 ac pins are in the correct place and the + and - are in the correct space)

the AC for BR2 comes from pins 1 & 2 on J101 and via F113

pin 1 on J101 goes to F113 then to the top right pin on BR2 (A.C)
pin 2 on J101 goes straight to the bottom left pin on BR2 (A.C)

Check that F113 is not faulty, there have been quite a few people who have been caught out with fuses that look fine but are faulty.

Check that you have continuity from the - on BR2 to the - Pin on C5. Do the same with the + pin on BR2 and the + pin on C5. You will have to remove the board for this.
let me know what the results are and we will go from there.
