Weak picture tube causing the AKB circuit to blank the video. Common old
Sony problem.
Sometimes a slight increase of the G2 voltage will extend the life for a few
months or a year or so.

Time to start looking for a new tv set.

Hello,

I have a Sony Trinitron XBR, probably over 10 years old. The sound is
great. The picture is okay too, when it finally comes on anyway. That
leads me to the problem. When I turn on the set, the volume comes on
immediately, but it takes a good two minutes for the picture to come
on. When it finally does, it flashes right off. Then it waits a minute
or so, then comes back on, only to go right back off. This flashing
repeats with the amount of time the picture is working becoming longer
while the time the screen is off becoming shorter. Eventually, after
almost an hour, it will quit blinking and be fine. That is, of course
until I turn it off again. If I leave it off for only a few minutes,
it will still have problems, but will not last as long as when its
"totally cold", around 10 minutes or so for it to work properly. I am
not much of an electrician. I was just kind of wondering what may be
wrong and if it may be worth fixing. Any ideas would be greatly
appreciated. Thanks,

Chris
