it.
I recapped the A board, (132 caps, I won't be doing that anytime

About two years ago I had bought a Phillips color TV, but didn't
feelike paying for the extended warranty. Now, the sound comes on real
low when first turned on, there's a 2" black bar at the top of the
screen that won't go away, and often when the set is turned on in it's

I have a 23-year old (try not to laugh) Technics SA-410 receiver.  It worked
fine earlier today, but I went to use it a 2nd time and I'm getting
absolutely no output out of either speakers or headphones.    Something
defitely failed within the unit.

numbers ...422 left. (Its not BF422)

Yesterday I unplugged my record player from my receiver, which was also
using the receiver as the power source. Later that day, I went to turn

I had one of these brought in, since the customer had accidentally severed
the VGA connector off  from end of the cable.
I figured out all but one connection.
Where I connect the "VGA CON" line on the HD15 connector?

This set has been focused (mechanically and electrically), all cooling
fluids replaced, lenses and mirror cleaned spotless, picture is still
overall hazy/cloudy.  Possibly nature of this set?  Model 9p6031c.

I have a Toshiba 32A10 (32" TV) that generates overwhelming white
noise (sound) from all CATV stations, from both the set's own
speakers, and from externally-amplified ones. The CATV signal is
fine; another TV can use that same cable with no noise.

I use a lot of external disk/tape/etc. enclosures or
