Thank you Zeno! I will try to get a proper service manual as I would love to have these tvs working fine as is to expect from a Zenith product. I will try what you suggested for the small 13" tv. Never opened it so I expect an extra cluttered space inside. I noticed the 19" has the trifocus picture tube and two focus electrodes. How peculiar! The 13" picture tube has areas of discoloration you can see when the set it is turned off. It seems like water entered inside the faceplate. By the way the tube seems good working.
