I hope that improves it for you. I know what it is to go after issues one at a time and when you see little to no improvement with each one, but they do add up.
The 21" Zenith I restored was that way. Original trouble started with a shorted sync/sound detector diode (not before sending me on a journey through the Zenith-unique sync circuit) and extreme vertical and convergence issues, which I learned alot from.
At the beginning, I could not imagine it ever being Zenith-bright/sharp. After several weeks, looking back made me realize how easy one could give up before its working as it should. Its just physics!
