The GE (actually RCA) 35GT690 uses the CTC187 series chassis. The tuner uses the VHF circuits for cable channels lower then 51 and the UHF circuits for the higher channels. This means that the VHF circuits have stopped working in your set. I usually find that this is caused by a defective U7301 IC in the tuner, the SIP IC labeled CXA1594L. This is a very difficult IC to change and all tuner ground solder joints should be resoldered too, so that should be done by someone with experience in the CTC187 chassis.
