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

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
