With the IF Module removed, can you turn up the brightness and get a raster?

Yes, you can connect your generator 50 ohm video output to C1 with the IF module in the set. Rock or position the tuner slighlty to mid-channel, or you can remove the IF in cable.

Google "Servicing a 1974 Zenith 19DC12 4 tube hybrid color tv" you might find this YouTube interesting. No connection to the author.

After all the times I've been inside the set I never noticed that there are 4 threaded inserts in each corner. I've never see an Avante with anything other than the plastic base, so I wonder what they are for. I was thinking of making some legs and screw them in so I can take off the base and open the bottom and not have to put the set on its side.

Okay, I'm going to give the generator to C1 with tuner disconnected as I am unable to set the tuner between channels as it's motor driven.

I'll also try upping the brightness with the IF removed.
