Zenith TV/VCR SRV1300S dead

[Mike]

a friend of mine gave me this TV if i could fix it, so i went ahead and got
it.

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.

The television 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 plz help.

I'm a novice and can't help you with your prob, however I am looking for a
new remote for my SRV1300S and can not find one anywhere! If you can't
fix your set, would you be interested in selling the remote, or have any
ideas on where I could find one? Thanks in advance, Squirmin_German.
