[ARC Tech-109]

At that time I wasn't interested in lugging the brutes around and they were looking to retire, I remember hauling a few of those big 30+ inch CRT's to the bench but never got into the RPTV's. I miss the days of the EZ triplers and sagging 3A3 heaters that took out the flyback.

Getting back to the Panasonic I see so many suspect connections I don't know where to start but D551 anode is just as good as any. First soldering takes a lot more than globbing it on the connections and hoping it conducts, they need to be heated until the solder flows. Those connections on the flyback are not up to par by any means. I see the majority of solder connections have not been touched and they are all suspect until addressed. Soldering is a skill that comes with years of practice, not something you can learn from a book. Honestly I think you bit off more than you can chew with this one.

And this is what separates the experienced. just a quick glance I see a halo around the anode of D551, the posts around the DY terminals esp #3 don't look very good. TPB4 looks to be shorting across to the adjacent trace for TPB3 just above R603. All of the connections around the flyback pins need to be reflowed and when I say this I mean heated until the entire solder connection melts and flows around the pin, simply touching the glob is not going to cut it and with all that has been done so far I wouldn't be surprised to find blown semiconductors. You're going to need a lot more luck to get this one working right again.
