I don't know what D610 does in the circuit. But I can tell you that it
probably is a Schottky diode that reads a lot different from most other
diodes. On my Fluke 12 a Schottky diode measures low one way, and the
other way the display blinks quickly. This how I know that a diode that
appears to be partially shorted is actually a Schottky diode and is
still good.

Hi Guys, can someone with a print tell me what D610`s purpose is in this

167
Ohms the
other way, have removed the RGB chip on the crt board, vertical output
IC,
HOT

> 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
