This one stays off frequency now. I can just touch the coil L204 (VCO) and it goes ballistic. Audio is good except when it is rumbling with the erratic picture. I called Ballard and they said they could send it off for overhaul for approx. $140.00.....cheaper than the labor I have already in it. I'm thinking about sending it off, since I didn't get any responses.
Thanks,
Joe

Seems to me in the older Philips/Magnavox set there was a coil/control that needed peaking in the IF/RF section. The section with the shielded area.
This was when the signal drifted off frequency shortly after the Channel was changed, about 2 or 3 seconds. I don't do many Philips/Magnavox, but I can check may database, although it may not be under the same Model #.

Replaced the tuner with one from Tip-Top and still having the same trouble. I can wiggle the VCO coil (L204) and the pic gets all "screwy".
Now, I am suspecting maybe the tuner was good to start with. Does anyone
have a schematic with just the tuner and surrounding area? My rebuilder wants over $400.00 to re-build this thing. Any help is appreciated, because I am about ready to throw in the towel on this one!
Someone please answer!
