Ricky, Brian, OT, Zoloft, GMAN???? You guys have any ideas what it could
be.
Well without looking Doobie, it sounds like a ten-year old set has run
its course. And those Ball-Wart sets are going at a good price... I know
what I'd do.
(Sorry I couldn't help more).

It has been 22 years since I had to repair a TV, but I still have the
books. Hope info is helpful.

It's too bad that you don't have a 25 year-old TV. It would
still be good for another 5 years or so.
Phone a TV repair shop - Munroe's in Sackville (if he is
still there) always gave me straight answers. He was busy
enough that he never had to suck customers in for work. If
it's not worth fixing, he should tell you.

LOL! Go to Ball-Wart's Doobie...

Are the B+ voltages at the fly back still 10-15,000 V now like they
use to be in the old sets?

No, Doob...it should be a fairly cheap fix.
The flat horizontal line is telling you that the problem is in the vertical
deflection circuitry, which is usually a single chip. The fact that banging
the TV sometimes fixes it gives a clue that it's probably a cold solder
joint, which once found, takes about 10 seconds to fix.
Even if you take it to a shop, it shouldn't be a terribly expensive repair.
It's probably a safe bet that it's more affordable to simply support your
local landfill workers and purchase a new television.
I agree with Dave. There is a PCB ( printed circuit board ) on the back
of the CRT. Check for cold solder joints. Just make sure the set is
unplugged and stay away from any high voltage , like the connection
from the flyback transformer to the CRT.
Some TV used to have a switch , which put a horizontal line on the CRT
so a tech could do a convergence alignment. If you have such a switch
it could be intermitant.
I really don't know.
The last time I had one looked at was on the recommendation of someone
in here. The shop was on Almon St and I was ripped off BIG TIME.
I don't know anything about the following but it was just posted on
hfx.forsale.
Hi all.....i would just like to say that if you are looking to get some
T.V
repair done or any other electronics fixed...That i would give Sidney a
call...(902-466-0061)Sidney fixed my 32 inch RCA t.v. in wicked
time....less
than 24 hrs...and has awsome rates to go along with that.....i have
gotten
my t.v. back in works better than new...Give him a call some time if ya
need
any repairs done... thanks Adam

30kV or better, at least thats what the bridgemaster radar display used
to be. Serious pain if accidently touched

Thanks Rich,
I didn't know if the voltages used were still that high with the
(modern) type equipment.
Yeah, 30Kv would certainly keep the cats out of you garden.....
It seems that the higher the resolution or the bigger the size the
higher the CRT voltage. I wonder what the voltages are in the new lcd
panels, they can't use the same power/current that crt's do
Probably not as high rich , thye don't have to illuminate the
phosphours, like you do in a CRT. Also no deflection coils. Been awile
since I've had one apart.
Oh, and Decca is now selling flat panels with the new Bridgemater E
radars, or it an option.
