I did a ring and continuity test of both the yoke and the fly on my B&K 944 flyback and yoke checker and both passed fine. The fly even moved the needle higher in to the good region once connected despite me forgetting to pull the HV rect tube as reccomended. This is the first time I've used the 944 after testing and replacing all bad parts in the 944 except the transformers and meeter (I could not properly test those, and had to assume they are good) so I can't really say if my 944 is giving me a good reading or not.
I did check between the top caps of the HOT and HV rect, and got a reasonably close resistance reading to what sam's lists. I have not checked the other windings of the fly for resistance yet, but will soon. I had actually ohmed out the fly a few years back just before I found the shorted damper that had been killing the HV, and some of the readings were not as close to sam's as others yet it still worked well after that.
If I can tomorrow I will do some more checks including the ones suggested (that I have not tried) and report back.
I believe it failed due to my blocking of the cabinet bottom vents (they got blocked because I had to take the set it was sitting on out of the room and set it on the carpeted floor) which caused over heating. The video circuits were acting squirily before it failed (intermitant noise, and I think one of the signals was intermitant as well) but not frequently or long enough at the time to worry me. The picture then shrunk horizontaly, and may have ran that way for a couple minutes before I noticed. The picture was only lit on the brightest spots during that. Once I noticed I cut the power hastily and on the next power up it had a nearly if not full raster, and only had light at video peaks. It will display light on the screen with decent video for an instant after switch off (it use to do this when the boost diode was open a couple of years back). I noticed that there is an approximate pencil thickness tower of wax in the HV cage that is fairly new.....the fly does not seem to run hot though so it may be nothing.
I'm not of timmy's mind set anymore because of this set. About a year ago I was convinced that the fly was bad because all else seemed fine, and I had chased my tail on all else except the fly, but then I discovered that the damper which had tested good before was shorted, and that got me on track.....a few blown dampers later I came to realise that this set liked to blow it's damper if the horizontal frequency was not close enough to what it is in normal operation....Quite wierd.
The good news is that I have a Philco with a virtually identical chassis and circuitry (only differences are control layout, tuners, and a noise inverter stage added in to the synch sep stage in the Philco) which I can trade parts (and maybe signals if I get the two in the same room) between. Already tested the HO tube and H osc. in the Philco.
