So the flyback transformer in my Samtron 75V has that annoying ringing sound. You all know it, and I want it to stop. My dad worked in TV repair shops for many years as a kid and even when he was an adult, and he was telling me that flyback transformers are designed specifically for one circuit and thus are difficult to replace. I was hoping modern CRTs use more generic designs...and that I'd be able to replace this thing. I haven't got the money for even a cheap CRT, and this one is pretty damn nice so I'd rather not trash it. Any ideas? How might I measure the flyback transformer's properties so I know what to replace it with?
i personally would say its too difficult and way too dangerous to go messing in the back of a CRT especially with the flyback transformer!.....unless you love soo much you make love to it each night; dump it and pick up another even if its a cheap one till you can afford a decent one
Well I'm sorry if I'm not a fan of the "buy a new one" solution. CRT danger is quite overrated...besides, my dad would be helping me, he knows a lot more about these things than I do.
You mean the flyback transformer? No clue actually, I've yet to open it up. My dad was just saying how they're specifically designed for circuits and hard to replace. I'm not too familiar with flyback transformers other than that they work differently from your average torodial...or so I hear...I'm not that familiar with AC. I'll probably take a look tomorrow. I have to replace the cable anyway, I get red/green/blue tinting (very slight) when stress is applied to certain parts of the cable...very light stress that is.
All you need to know is the TV make and model. That's usually how they are categorised in catalogues for replacement parts. They are relatively specific to the chassis used the TV, so you won't be able to just find a 'generic' one that will work.
This question falls under the catogory of 'If you need to ask, you shouln't be doing it', if youre driven enough and want to know, find a TV repair shop willing to take you on as an apprentice, I doubt you can find people teaching HV electronics and TV repair these days
are you sure the noise comes from the transformer itself? a little tip: try cleaning the tv inside and spray the transformer and the areas around (not on parts that becomes hot) with some clear coat. perferably something that is a bit thick and flexible. it's not by the book, but it can help in some cases.
Pretty certain...my dad repaired TVs for years, he's always told me that was the flyback transformer. This isn't a "if you have to ask you shouldn't be doing it" situation. I'm not some fool that's never picked up a soldering iron before, I've just worked with CRTs only a few times. I was asking specifically how to measure a flyback transformer so I can find a suitable replacement part.
i know... and CRT's aren't that dangerous if you know what you are going. (i have worked on them myself) you could measure resistance and inductance on the primary coil and try to calculate ow many turns and so on the transformer has, and then go from there.
