Zenith Projection TV Heaters

[[email protected]]

I inherited a Zenith PV5263RK that has sound and no video. I read a
post to check the heaters. How do I check to see if the heaters are
lit. Is this a visual inspection? What do the heaters look like?


If there is a newsgroup that is better suited for such a question,
please let me know.

Thanks

Look at the lower section of the tube.
If lit you should see an Orange glow.

To identify the two heater pins check with an ohmmeter : they should read
from 4 to 10 ohm.
