Voltages good then. Every time I've had an Rx issue I've had bad voltages there. One required a new multiplexor (because of excess probing) and the other needed the trifilar toroid rewound. I did have one where the soldering on the BPF caps was not making correct connections. I had to reflow the solder on those caps... Double check T507. I might start with a signal at the antenna and start tracing back through the receiver. Maybe someone else has another idea...
