D610 is placed parallel with R632, 0.1 ohm 2wt, and R641, 1.0 ohm 2wt. All
are tied to hot ground. Looks like a clamp for a current sensor to IC601. The
schematic is on the T/A Members download area.

> Hi Guys, this KV32FS12, BA5 chassis, has a constant tick or click like you
would have from a relay but it`s definitely coming from the flyback, B+ line
is fluctuating from 35 v to 65 v up and down constantly, 200 v line is
constantly changing from 108-135 volts, HOT is not shorted, pulled CN502 to
remove the rgb driver from the circuit, nothing
> changes, I don`t have the print so need some ideas, tia, Larry E
