I got the '88 Zenith 19" cleaned up and fixed. The original problem was a vertically stretched out picture. The culprit was a defective 22 uf cap in the vertical circuit; but, I also replaced a 100 uf cap and a 470 uf cap in the vertical circuit that were questionable. I also replaced a 100 uf cap in the power supply that was weak. The 22 uf cap in the regulator circuit was fine; so, I left it.
I think this was the first Zenith that used a single board "module" for the chassis, instead of multiple modules. I think this one and the 9-470-based 19" Zenith's were the last to use an LED channel readout and were made until around '91.
I'm probably going to let my flea market friend try to sell it for me. It has a nice picture; but, I'm running out of room and I'm really not into collecting TV's this new.
Video shortly on the Zenith.
