for some reason, the 6v regulator is holding steady around a mere 4.8V

hmm, anyway, if you press power at the same time you put the tape in, The
motor will kick on, and start taking the tape, but it wont thread up to the
heads and play. It just shuts right back off. Neither of the LEDs on the
front ever come on either.

Im leaning more and more to the CPU board.

Any ideas?

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?
