The contrast control in this set is responsible for controlling degeneration in the cathode of the video amplifier tube, and as a result, the strength of the sync signal. If you put the correct control in, it might fix the problem since it's more than double its stated value. If it doesn't, try adjusting AGC till it's in a range where you can live with it (if AGC is adjustable). You can also try putting a 5k resistor across it, which would lower its total resistance to around 5k. That's a lot closer to spec than the 10k it's reading at now.
