Hello Buck,
I think you will find the schematic at
http://schforfree.seedhost.com/archive/?path=Sony%2FVideo . Look for the
file Sony KV-2@FS100_KV-2@FV300_KV-2@xxxxxxxxx I have already reached my
download limit for the week but you can download it free. You don't need to
register for 1 download.
Hope it's the right one for your set.

Buck, model is a typo right (KV24FV300 right?) don`t have the schematic but
I have run into one or two of these,
check IC600 and see if voltage is constantly fluctuating on pins 2 & 3 if
so replace bridge D611 (part of it
will check bad) USE SONY ONLY, it`s a special high speed bridge part #
871906240.
Also check R640 1K 1/2 watt if it`s burned up you`ll have a bad IC600, this
is supposedly caused by an arc
from the crt dag to Q600`s heatsink which isn`t grounded so it jumps to
IC600, theres supposed to be a bulletin of
some kind to stop this arc but I don`t have that info, Sony ASC`s might be
able to help out, this is all I have, hope it
helps, Larry E
