oops. It is a brown black blue, which is 10 megohms.
its only reading as 2.
Is this the problem?

Remove the HOT and try......if it still shuts down , your Hv section
should
be OK
Check R607 10 Meg

I try to power it on, the tv will cycle for a sec and shut off.
I checked the HOT, and it tests fine.
I also read that there are two to-220 regulators that typically go
bad
on
these, I went ahead and replaced the 7805, and the 7806 regulators,
and
the
set still cycles.
I pulled the power supply back out and checked the diodes and
voltages.
The
secondary supply diodes test fine.
I checked the volteges on the power supply, the 113vdc test post
tests
a
normal voltage, and I checked the voltages at the regulators and
they
both
appear to be normal.
There is about 7volts on the 5vdc regulator with a 4.8 to 5v output
there is 11.5 vdc on the 6vdc regulator with about 5.8 to 6vdc
output.
The volts are normal. When i try to power it up, it will cycle too
quickly
for the HV to come up.
If i disconnect the TV deflection board completely from the circuit,
it
still cycles.
Im stuck.
Any Ideas?
