Sony KVX2142, ae-1c chassis. Picture is severely squashed vertically, with
bright band in the centre. Preliminary investigation suggests that the HT is
ok (I get a picture), and the horizontal drive is also ok. The 27V for the
vertical deflection circuitry sits as 12V; there must be some path from the
12V to the 27V.
According to the circuits, the FBT generates the 27V supply via a resistor
(0R47), diode, and a elec cap. There would appear to be no volts either end
of the res. This would seem to indicate the FBT is kapput, but only the
secondary that is used for the 27V bit. Is this possible/likely?
Before I splash out £50+ for a replacement, I'm wondering if I could make a
separate 27V supply.
