Hi:
The vertical deflection went out on my TV a few days ago. It started
acting funny a few days prior to it going out altogether. I'd turn the
set on and the thin horizontal line would appear, then fully deflect, and
oscillate back a forth a few times, sometimes staying a line for a min or
two, then deflect to full screen, etc. Now it just stays on as a thin
horizontal like across the screen, about 1/8" thick.

Are there any things prone to failure in this set that I should look at?
OR, any common problems with this set in general? e.g. bad solder joints
around?
Thanks for any insight!
John

Solder connections - if the ouput IC hasn't blown by now. Sometimes if you
put it off, the things blow up.

Hi Mark:
Thanks for the reply...when you refer to 'ouput IC' I assume you mean
IC421 (LA7832 -that produces the deflection)??
Very interesting second part of the story...sometimes I can get back to
normal deflection by cycling through the input selections (AV1, AV2, and
TV)...the changing of the input signal sometimes triggers the deflection
to operate normally. After maybe 3-10 mins, something happens and the
deflection goes away. Guess I need to poke around with a hot soldering
iron...Any additional comments based on this follow-up info?
Thanks
