Where to get Magnavox flyback transformers

You will be extremely lucky to find someone who has stock on these, if they can still find them!

Most people are trying to dispose of these sets rather than fix them. If you look at the value for the time involved, plus the cost of the parts, these sets are not worth servicing.

Since the FB is bad, chances are that there are other problems to also be serviced. Considering the age of the set, I would not be confident in its rerliability.

If you want a newer CRT set, there are many deals around t'll they run out of them.

Why do you say "Since the FB is bad, chances are that there are other problems to also be serviced?"

The vast majority of flybacks that are bad, IME, are the sole problem. Now some of the Philips products hav been known to have concurrent failures of the flyback oand other parts, so is this one of those?

I like how the flyback being bad was diagnosed on the newsgroups. LOL I guess the set is not worth having it properly diagnosed by a technician given its age and known additional issues, cloudy coolant.

Yes, in many more cheaper designed sets, like Philips, when the flyback fails it does usually require some additional parts. Not often much more than the HOT, but sometimes much more, NAP D7 chassis comes to mind for one.

Many times when replacing the flyback, I also found the HOT to be damaged. On some occasions, I found that I had to replace a number of high ESR caps. When considering the labour alone, the customer can almost buy a newer set with newer technology, and have a full warranty.

The D7 chassis was exactly the one that I was thinking of. Other than that, and the Sony BA5 ABL resistor, I have found it to be rare to have to replace other parts.

I think the point is that a consumer or weekend mechanic trying to fix anything that he is not familiar with should be aware that there are infinite possibilities for complications.

Well, a fusible resistor is open, and one of the transistors shorted on the collector and emitter. I don't have a resistor yet, but I got the transistor. I figured I'd pick up a resistor in spec somewhere in town.

I've had the transistor for a few weeks now, waiting for the transformer. So something else did go with it, but that transformer is the problem right now.

I would agree that there maybe something else wrong with this set that you have. I have had people bring me in sets that are dead claiming the picture tube died so that is why there set is not working and wanting to know what the picture tube will cost. All because they look on the internet to what you call these newsgroups and do it yourself electronics forums which is a bunch of crock. I would take this set to a qualified repairshop to have it checked properly if it means so much to you to track down a flyback for it. If not, then I would have to agree with the other guys is to go out and get yourself a new set.
