Usually, what happened in those is the 100uf, 200V cap behind the flyback would fail, causing a picture that sometimes looked like it was out of horizontal sync. If the owner took it in for service as soon as it started acting up, a new capacitor would usually get the set back in business. However, many owners kept watching them and the bad cap would eventually cause the HOT to short. When this happens, it often blows the STR, the TIP47 transistor on the heatsink, and a resistor (1Kohm, IIRC; but, it's been a long time), and the solder-in B+ fuse (a tiny picofuse). In other cases, a few more parts in the power supply will get fried.
