Default JVC TV repair help

Is standby B+ getting to the micro? When power is turned on does the
jungle chip provide startup H-pulses to the H driver circuitry that feeds
the HOT? Is the power supply coming on and regulating properly to provide
B+ to the flyback?
These and lots of other things you can check without a schematic

I am trying to fix my JVC AV27BP4 TV. The TV has no HV, the HOT
appears good but it has no startup drive. The startup drive is driven
by another transistor which appears good, and that just hooks to a big
JVC IC through a single resistor, the VC2024Z.
I'm not really sure where to go from here... I can't find any service
info on the tv, or a datasheet for the VC2024Z(yeah right!). Is it
likely that this IC could be bad? Or should I start checking all the
discretes around it... Any tips would be greatly appreciated!
