Default Zenith srv1300s tv vcr dead

ok. You might be right.

Here is where it gets funny.

I said what the heck. I tried to put a tape in, and it almost took it. the
motor wirred for a sec and then wirred back out. I manually fed the tape
into the unit. I plugged it in, and I hit the power button, it powered on,
and threaded the tape out, and ejected it. Powered back off and wont power
back on. The TV never came on at all.

Does the deflection/HV board require a power on signal from the VCR board?
if not the hv board is got bad components, if so, then the VCR board is bad.

Any ideas? I checked the HOT its fine. I didnt check r607 yet.

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?
