I have three HR22 DVR's. All three fail the system test with Error code 43-288. Two DVR's pass the satellite setup. One DVR during satellite setup shows a red X on 103* odd 13V Tuner 1. I switch cables and retested and the problem followed to turner 2. I switched cables back. I ran a new cable from tuner 1 to out 6 of the Zinwell MS6X8WB-Z switch. Retested with the same results. 103* signals are in the low to mid 70's. Any help here.
