My guess would include a failed tube, probably a 6AF4 UHF tuner triode,
or a broken cable if the power supply is separate from the dipper.
Getting into the dipper probably requires removing the screws through
the U shaped wrapper and sliding it off the bottom. Don't take out
screws that don't hold that wrapper on.
Could be a power supply problem too, but the tube is the most likely
failure.
