Just a cleaning won't fix this one
The seller of this RCA obviously doesn't know much about TV servicing. Any television set with horizontal hold that "won't stay put" needs more than just a cleaning to get it working again as it should. Seems to me the horizontal AFC circuit is defective. I'd check that first. The problem could be a misadjusted horizontal-oscillator coil or weak AFC tube at best or an off-value resistor or a leaky capacitor in that circuit at worst. Since the seller also mentions being able to get a "light picture" on the screen when the set is on, I would also suspect that the CRT is weak (not uncommon in a set of this vintage) or perhaps there is a problem in the video amplifier circuits (if the contrast is weaker than it should be, and cannot be adjusted to normal with the contrast control). In any case, a simple cleaning won't repair this vintage set.
