Due to age, some capacitors simply leaks, or lose value. Is common with electrolytics. Since this small TV uses a lot for inumerous functions, various curious symptons can occur.
Even with some "half bad" caps, the TV can be adjusted to almost normal operation, but some controls become very picky.
I have one TV-700U working and one spare (with dead CRT). One had ALL electros >5µF bad, and other had 1/3 bad. Statiscally, I bet that at least some can have problems.

If are some bad caps at same time with some RF/IF misaligment, the TV will be very difficult to use.
