I recently picked up a non-working 847 to replace the display on mine. The numbers on my 847 were losing some of the segments but the inoperable 847 had a good display. It was an easy swap and now my 847 has a good display. The OP I bought the salvage 847 from told me he had purchased it from an estate sale but the rig was 'deaf' when he connected an antenna and powered it up. ?I hooked it up to a watt meter and dummy load and the rig will not transmit on any band. I started the alignment procedure and discovered the PLL adjustments showed minimal voltage (.022 volts) at TP20001 and would only change a few thousands when I adjusted T2001 through T2005. ?

I am wondering where to go at this point to start troubleshooting this issue. Is it worth pursuing trying to repair this non-working rig or put it on the shelf to salvage parts from in the future?
