Yamaha A/V receiver model:RX-V1070,year:2000,no power only relay
click.I replaced the following:

Right channels:
2SA1302=2SA1943=NTE2329=PNP
2SC3281=2SC5200=NTE2328=NPN
R225=0.22 ohm,5w,dual emitter=Sony # 1-234-182-11,Onkyo # 4500031

R223=4.7K ohm,1/4w,flameproof=Yamaha # HV456470
Q139=2SA1145=NTE32
Q136=2SC2705=NTE31
R201=1K ohm,1/4w,fuseable=Yamaha # VK189000
R202=330 ohm,1.4w,fuseable

and now the unit comes on and has audio from only the front center
channel (left & right) but none from rear channels or fronts A or B
channels.Anyone have any common repair tips?.Thanks.

At a first glance - make sure the pre-main jacks are connected at the rear

STK rear channel amp is bad as well.
