Well, I just blew almost $50 straight to hell! Got the new HR flyback and HOT, installed them, and the set had a great picture - for about five minutes. Then, the POS shut off and started squealing. Yep, the new HOT was shorted and the heatsink was hot as a firecracker. I had previously checked the B+ and it was not running high. Then, I checked the electrolytics around the power supply and HOT. None checked bad. Then, I received a nasty shock from the main filter cap. I said "that's it" and ripped the chassis out of the set, pulling the HV lead out of the new flyback in the process, and then threw the whole damn POS on the garbage pile.
You'd think I'd learn sooner or later. So, do me a favor, guys. The next time I get on here with some POS modern TV and mention that I'm ordering pricey parts to fix it; remind me that the TV really is a POS and I'd just be throwing my money away and that the amount of money that I'm planning to spend on that TV can go towards paying bills or buying a "real" piece of VINTAGE "meant to be repaired" electronics!
Let me tell you, TV repair (or should I say modern TV repair) is ceasing to be fun anymore. I don't remember having such problems back in the '90's when I was still repairing a fair amount of TVs from the '60's up until the late '80's. These newer TVs are cheaply built and they are running the major components to the limit. If the slightest thing goes wrong with the circuit, something blows up. In the old sets, circuits were designed with greater care and parts were not ran to their limit. When something went wrong, it was usually noticed in the operation of the set.
I've got another 31" CTC203 RCA with a brand new flyback and HOT sitting on top of it. It's been sitting there for 2 or 3 weeks and I can't even bring myself to install the parts because I'm afraid we'll have a repeat performance. Yes, I know about the loose drive coil and the bad flybacks; but, this will probably be the one set that will have some oddball problem.
