TANDBERG CTV2 CHASSIS

< Back

There’s lack of both height and width, but I’m not sure
which control to adjust. The brightness and colour
rendering are both all right, as is the sound.
This chassis uses a blocking oscillator switch -mode
power supply, and it would seem that the h.t. output from
this is low. The easiest point to check is at 8751 at the
bottom of the right-hand panel. There should be 120V at
one end of this resistor and 160V at the other, h.t. feed end.
If the h.t. is less than 160V, locate the grommet in the
screened can beneath the c.r.t. neck and, using an insulated
tool, turn clockwise for 160V. If the picture size varies
erratically, D975 inside this can is suspect.
