It's good that you know how TV's can bite, I'll still have to post this in case someone having your problem and reading isn't aware of this and feels lucky- If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. could be a problem with the screen potentiometers block. should be located on the chassis close to where the HT lead passes on its way to the picture tube. Good luck

Check for 28volts coming out of the flyback through resistor and rectifier , if it is there then you may want to look at the vertical output i.c , it may be gone or cold soldered which is common in those sets.
