Hi,

This Magnavox TV model 20MS2331/17 (mfg. June 2004) came
into my shop. Note: I do not have a S.M. for this model.

Here is more information: If I keep changing the channels, the
TV stays on, but once I stop, it goes off. Note: Muting the sound
has no effect on the problem. When the sound comes on, always
after the picture, it is normal. HV measured aprox. 26KV.

My Original Post:

The TV will turn on. A moment after the picture comes on and
you hear sound, the TV turns off. I checked the regulated B+
source for the horizontal output circuit and it measures +94.8V.
Without the S.M., I don't know if this voltage is normal.

Do you have any ideas what is causing this?

Thanks in advance, Brad
PS,
Thanks to Robert for his willingness to help me, but the schematic
was for a different model TVand the symptom is different. This TV
doesn't have the part he indicated.
