Zenith H2447R 19" Porthole TV

[Crist Rigott]

I did a terminal strip located near the front of the chassis. It was pretty much self contained and consisted of just a few parts.



During the removal of the old parts, I noticed that there was that yellow CAD plating residue on parts of the terminal strip.





What I do to clean off that residue is I use CLR cut 50/50 with water. I brushed on a little with a cut down acid brush to about 1/2 inch long. I then "scrub" the area with the acid brush. Then I mop up the area with paper towels, Q-Tips, and alcohol. The residue comes off very easy this way.



I then replaced the components and cleaned off the flux, and I'm done.



Since this picture was taken, I added some more solder to the lower ground terminal.
