Toshiba model 24AF44, Ch. M3M627 focus and luminence problem

The customer said that all of a sudden the screen went out of focus and the brightness drastically reduced. Although I never suspected an adjustment problem I tried the controls just to see. The flyback screen control will raise the screen and the focus has some effect but does not have sufficient range. I have no schematic for this set. I'm thinking bad divider in the IHVT or is there perhaps an external resistor in the divider circuit that might do this? Another respondent suggested a possible focus to G2 short however there does not seem to be one. Or does anyone know if this problem is common to this set? Thanks. Lenny.

I just wanted to add that after running for awhile I also noticed that the flyback is quite hot. There doesn't seem to be any other noticeable problems with the secondaries.Lenny.

Replace the flyback.

Replace the flyback and HV multiplier assembly to start with. Most likely this will fix the fault.
