I received tubes for the tuner.. Made no difference as for UHF or anything else (No Change).. When changing the VHF tuner and when I go past channel 2 the program comes in as clear on that channel as channel 3.. So using a signal source that's set to channel 3 comes in perfect on this TV on both 2 and 3 channels.. Is that an issue, or should I not worry about that? I don't see a switch anywhere to turn UHF on or off, and the black coax cord with the RCA jacks on each side is connected to each, and there is also a red wire that looks to be the B+ connecting in between VHF and UHF tuners.. I did check all the resistors that are pictured near the tubes, and all check in range, there are two caps in that area that are also pictured.. I haven't checked them, and really have no reason to seeing how all the orange drops that I replaced were good.. There is also that aluminum looking cap with a red line around it (Also pictured).. What also should I do?
