Sylvania CX4161W 19" Color TV needs help
 

I got this with the VCR haul this weekend. When we tested it, it seemed to have convergence issues, but when I tested it at home the picture was very good. The only thing was that the vertical was a little off. I adjusted the vertical height and that solved the problem. This will replace my 1979 Quasar as my daily driver.

Looks nice! I like it.

IIRC it has a small convergence board that got cold joints.

I had a suspicion that this TV has the dreaded "Instant On" feature. My suspicion was confirmed when I turned the set on and the picture came up in three seconds. I really want to disable this before I put this TV into regular use. Does anyone know how to do that?

I know that some tube sets had a switch that cut that feature off magnavox was one of those sets..Timothy

We'd need to see a schematic to determine how the "instant on" is accomplished and if there is an easy way to defeat it. The easiest thing to do would be to operate the set from a power strip.

Up until about '87, one of the local hospitals had sets very similar to this in the rooms. The ones they had used the E-08 chassis that used a power transformer and three big plug-in modules. The CRT was a delta gun tube. They had a wired remote and a motorized tuner.

If the power strip method don't float your boat, get a schematic for it and examine the CRT heater wiring...
This set may have a "vacation" or "instant-on", etc. switch to disable it (look for it on the back).

get one of those remote switched outlets sold for Christmas lights. its a small remote that has 3 buttons, for 3 different remotes. Then plug in the tv to it, leave it on (I assume it has a manual switch and not a logic switch). This way you can defeat the instant on AND have a remote to turn it on. I use this setup on my SS Avanti, works great.

Hello, This set if its' a 19 inch set uses a E-21-_ _ (fill in the number) chassis. If the number is over 10 it will have a fast start crt powered by a 3 turn winding on the flyback. If that is the case just enjoy as you are not doing in the crt. All the best,Tom

Well, I got this TV all set up with my new converter box and it was working perfect for about 2 hours. Then, all of a sudden, the focus crapped out. Any ideas? There is no sharpness/focus adjustment on the outside of the set.

What is the model,chassis number? If the set has a quad-line CRT then focus is generated by the tripler most likely dirty or open pot on the chassis. If the CRT is RCA type inline gun then trouble is most likely in the intergrated hi voltage transformer. Again really need the model & chassis number to help you. All the best,Tom

OK Thanks. Sorry I haven't gotten that yet. I've been hassling with that converter box.

If you want help, you're gonna have to give us some meat - model, chassis number to start - it's the number one reason I skip threads - no chassis or model number, no help from me.

Sams, manufacturers and cross references all use the chassis or model number. There isn't a single listing for "1974" under Sylvania in any cross reference. These aren't cars - you have to give up the model and chassis, in writing, so the search will work. Taking a photo of a model/chassis number doesn't work with search.

Looks like it's a CX4161W (Chassis E08) in Sams 1481-2.

It's the same chassis that was in the hospital sets that I mentioned above. It will use a delta gun tube. For the HV/focus, it will use a tripler and a focus control assembly. I've seen the tripler go bad in these and I've also seen the focus control assembly arc and burn.

The Model No. is CX4161W. The chassis ID no. is E080103-4213288.
