Just wanted to say thanks to Both "the Wizard" for helping out Rick....and
Rick for passing
that info along to me. Sure enough...1 ohm resistor was blown due to a bad
LA7839 Verticle
Drived killed by it's dried up 100uF Capacitor.

Here's MY bad luck....Found a source for the parts, replaced them all, and
in my excityement
to get the TV reassembled I went to lay it down on it's face to make it
easier to slide the back
on and got a SMALL bit of my shirt sleeve caught on the end of the picture
tube. It twisted the
little driver PSB enough to break the vacuum "nipple" and PSSSSSSSssss. ...

Yep...broke the Tube's seal and lost the vacuum.

Dohhh...That was the SHORTEST repair I've EVER done. Guess I should stick
to what I do
Vintage Synthesizers. No vaccum tubes and fragile bits to break in a
Mini-Moog !

Thanks again gents for the help. Sorry ONE klutzy move made it all for
nothing.

Cheers....Dean.
 
OUCH!!!!!! I know that feeling. I worked in a TV repair shop, where the
man (Owner) would leave the backs off the TVs all the time (Why I have no
idea). I know several that I walked by, and my Jeans would just "Lightly",
brush against the neck, and boom, "Pssst". You just sit there and cuss
everyone but yourself..:) LOL

What I would say, MAYBE you can talk to a Locally owned TV repair, and see
if they have any used Tubes. I know the one I worked at, would have them
all the time. But that was 10+ years ago. Many may not even store the used
ones anymore. But worth a shot.

Hahahaha you're NOT only one, I did too before few times. OUCH!!!
I can't hear that Pssssssssst... because I wear hearing aids and can't
hear that kind of noise. Only time I hear air rush when I suddenly
crush a nipple on purpose. Whoosh.

It takes bit of abuse to crack that nipple and I'm surprised yours
fractured too easily. 8-O

For this reason, we keep their backs screwed on with 2 to 6 screws
depending on their size with small ziploc bag of loose parts inside
each unit with power cord stuffed in.

One tech took down a unit and caught a cord trailing from a RCA 13" TV
and yanked it off shelf. BOOM! Hit the concrete face down without
imploding, face intact even no cracks. Opened it up and found whole
stem along with yoke broken loose. Luckily had another tube and few
jumpers on that circuit board, TV is fine. :)

RCA 13" sets has very clever HV regulation design right off raw B+
without regulator at all. (Yet, no breathing at all). I wish it is
used in 25 and 27" to combat that annoying breathing pictures.

My old emerson 13" is AWFUL, breathes very wildly (regulator not the
problem).

Cheers,

Wizard
