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 panel. The rear channels would have a separate problem, though. Could be the STK rear channel amp is bad as well.
