Magnavox TV/VCR CCT132ATO1 (Symphonic TVCR13E1) Odd Problem!

Hi,

In my shop is a Magnavox TV/VCR CCT132AT01 (Symphonic TVCR13E1) that
"shuts down" after turn on due to excessive B+ voltage. If I unplug CL603
(multi-wires connector) from main PCB and measure Reg. B+, it is normal +112V
and it is adjustable via VR601. However, if I plug in CL603, which in effect
adds a light load (power is off) to the power supply, Reg. B+ goes up to
+120V(!) and it can't be adjusted! Did you have the same problem?

Thanks in advance, Brad

Hi,

I replaced C604 & C626 both 33uf 10V (low cap). B+ reads 117V (power
off), then at power up, drops to +112V (normal) for about one second, and TV
shuts down. Note: HV measured around 22.5KV when set turned on, but not long
enough for screen to light up (shuts down). I don't have SM for this set.
Either a problem exists in the safety shutdown circuit, or there is an outside
"trigger". Note: There is vertical deflection activity.

Thanks in advance, Brad

Hi Mark,

In this case, it has nothing to do with the VCR. VCR wasn't used when it
happened.
