I would start by checking for bad solder connections around the Frame/Vertical output stage.
If you have the circuit diagram you could try disconnecting the relevant protection line... but you must switch off as soon as the screen comes up you don't want to be leaving it with a bright white line too long.
As you can appreciate, any problems with this stage will cause a bright horizontal line to appear which could leave a nasty burn mark inside the screen if left too long in this condition, to prevent this damage the set shuts down.
