Modern Zenith model years start with A 1970, B 1971,

C, D, E, F, G, H, J, K, L, M, N, Y, Z, then A, B, again etc.

These are the regular line. Like cars they start coming out

late summer. Always a sales meeting with good food & all

the free booze you could drink before you placed a big order.



Decoding models is like this.

SK1961W

S=remote

K=model year (1979, may be built 1978 )

19 = 19" screen size ( like yours dosnt always stand )

61= level, higher ## is better

W= cabinet flavor. W= walnut. X= white P= pecan etc.

Any numbers after the cabinet are very minor changes service wise.

( SK1961W11 )



CTC177 is from the family of CTC175, 176, 177, 185, 186, 187.

Almost a 100% failure rate of bad PC cons in the tuner area.

Newer ones are better after some solder changes. Otherwise they

were very good sets & predictable. Google CTC 175 class

action suit.

BTW do NOT resolder it if there is no problems, too much can

go wrong ! Very small SMD's in a crowded area & I smoked a few in

my time !

So all of the C39xxx sets would have come out in 87? Makes sense. The V3912W must have been a KMart or WalMart set based on what you have said. "12" must indicate it was the cheapest cable ready set Zenith made that year.
