Starting a Zenith 16h23

Another problem with these was the vertical integrator. It looks like a brown ceramic capacitor but has three leads coming out. There is a three digit number on them which you can put into your search engine and find out the insides, If I remember correctly is three capacitors and two resistors. That's if I remember. These cause vertical symptoms like the picture you posted.

I thought if the vertical integrator was bad, you wouldn't have any vertical lock?

The only thing I can see wrong with that picture is the vertical linearity is out of adjustment. Stretched at the top.

My 25nc33 had a bad integrator that caused linearity problems. I'll check the schematic tomorrow but I think it may have two integrators.
