Hi Everyone,
It is a Toshiba CX2168C, #8806. The standby PS is an unregulated flyback
circuit using an STRD-1005T chip, followed by a zener at one output, and
with a linear regulator on the 5V. The unregulated voltages from the
SMPS to the linear stages are about twice what they should be.
The only thing I can think of are shorted turns in the primary of the
flyback transformer, changing the turns ratio and thus the output voltages.
Any comment or advice?
Thanks, Peter
