I've got this apex 24" tv with an LG A59KYL220X08 tube inside. I can't for some reason get an impedance read off of the yoke. My digital multimeter won't give me a read for some reason. The tv works fine. I unplugged the yoke connector and tried getting a read off both the plug and the solder points. Would one of the 8liners chassis work with this? Does anyone know if this will work?

So when you ask about impedance.... sounds like you might have a meter that reads inductance??
This is actually the most important reading. The Horizontal inductance is most critical and the leads to connect to almost every yoke is Red and Blue.
Hope this helps

And if you are using just a plain jane digital meter you'll only be able to read the yoke's resistance. (very few meters read inductance)
If that's the case then you would be using the Ohms function. (omega symbol)
Not as good as inductance, but will get you in the ballpark.
-
as long as you will be using the same scan frequency as did the tv , it should display a pic .
tube number sounds like a flat crt . the displayed pic will likely be distorted horizontally.
(do NOT opperate long with severe distortion - can stress the H output stage)
flat crts require additional geometry correction
-
Actually the tube isn't one of the flat ones. At least it doesn't look it.
-
then try it .
low Hdeflection would likely be too much of a load ( inductance too low )
overscan could be too much inductance .
same can apply to the vert windings....

My only concern is that I might blow up the chassis. If thats not a problem then I'm good.
