Sansui QRX 7500 A

I recently purchased a Sansui QRX 7500A. It had a few problems and I had it serviced and repaired. I was told all functions work properly. I hooked it up and reel to reel, quad 8-track, cd's and tuner played wonderfully. I put on a cd-4 record and rt channels played. No movement at all on frt left or rear left meters. I put on a regular vinyl Lp and switched to 2 channel only. Left side did not play. I was wondering if there could be a fuse in the phono input circuit since all channels play in the other modes. Just not phono mode. Thanks in advance.

Seems to me the 'service' should have included checking the phono section.

I doubt there is a 'phono fuse', but it could be just dirty switches or poor connections in the phono circuit--these circuits rarely have problems, but it could be bad caps.
