Check again that the voltage 30 volts is present if it is then remove the selector from the plate, remove the cover and solder the insert very carefully wash and dry it with hot air or wait for it to dry ... do not leave joints in the welds. .. re-solder the selector on the board and try again if it remains the same try another selector ...

Thanks, I already solved the fault as you mentioned, take out the tuner from the chassis, remove the cover and carefully solve the tuner insert clean it well and verify that it does not make contact with other tracks, then assemble it again and mount it on the TV chassis.
Successful result when switching on I was able to change the channels normally.
