Question about Toshiba Televison & Video
That sounds like the focus is going out of specification due to a dry solder joint or bad connection.
Checking the EHT distribution box for a bad connection could be fruitfull.
Use utmost care as lethal voltages are at this point!
If the picture recovers slowly it could be a tube base problem.
I don't think it will be much other than the Focus voltage is going up and down.
