Does this problem happen when using the tuner or does this problem also
occur when using the composite or s-video inputs as well? The first thing
that comes to mind is an intermittent (obviously) in the video processing
circuit, maybe missing voltage from power supply.

The power supply I have take it home and checked ok.
It is very good picture when just turn on and it was
not had been turned on for a long time, and will stay
longer time before it go to shutdown. If it begin to
shut down, or just one time. It would shorten the can
be seen picture.
I did not ever meet this problem picture sceen
before, so that struck can not move and don't know
what should be done on it. My schematic is little bit
different from it.
Please all super TV guys, Please help me.
