1976 RCA picture problem

[zeno]

OK I pulled the manual & its a simple set to deal with.
For the others its the B&W chassis with modules. A common & good set.
Before we go any further need to know what experience you have.
Also if you have a meter. You WILL need a meter for the size problem.
Let me look on Utube for a tuner cleaning video. You can use
WD40 but its best to use very little & put it in the best places........
