Default Zenith srv1300s tv vcr dead

changed it anyway (10meg) and it does the same thing.

it wont let the tape go in. You can hear the motor come on, and then it will
switch direction to spit the tape back out.

if you push the tape in, and hold it half way, you can hear the power supply
cycling (tick tick) through the speaker.

the monitor never ever comes on no mater what you do.

Maybe there is something wrong with the TV and causes the CPU to shut off.

the HOT tests fine, in circuit and out of circuit.

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?
