1980 Sears/Sanyo 19” Sensor Touch - Model 564-42072050

[Quadra]

Hi everyone, new to these forums!

Recent curbside find was this 1980 Sears Sensor Touch set (which upon further research, looks like it was made under Sanyo). It’s one of those sets where the channel up/down buttons are sensors that you just touch your finger on, and it moves up/down the presets you have set on the right.

Went through and cleaned all the adjustment knobs, turns on with snow/sound (although it’s not steady at times) and noticed some things wrong with this:

- The channel up/down “sensors” do not work, as it hangs on one preset (as seen in the first picture). Tired to hit the sensors inside with Deoxit with no change.
- Tried to use the channel tuning knobs back to tune back channel 3/4 on the preset that it hangs, and when hooking up a game console through the VHF input on the back, I get no picture whatsoever.

Any advice on getting the set tuned back to channel 3/4 and getting a picture to appear?
