Yup: below you will find a little “Return of the Jetsons” video post on a 1970 JVC Videosphere television repair: a CRT-style/picture-tube-type TV, in glorious black-and-white. Customer “found us on the internet” and brought the TV to us with a complaint of “low sound.” We were able to solve the problem and complete the TV repair, recapturing a moment from the customer’s youth, with a most definite coolness-cachet for his cadre o’ compadres.
JVC (Japan Victor Corporation), founded in 1927, produced Japan’s first televisions. They introduced many innovations and high-quality consumer electronics, including the VHS recorder. They began production of this space-helmet gem in 1970 and sold them into the 1980’s. I don’t recall ever seeing one or fixing one at the shop before (sadly, this one lacked the add-on alarm-clock-base feature! As they say these days: want!)
As you will discern from watching the video, the CRT (cathode-ray tube, in the original parlance; “cathode rays” are electrons) or picture tube is still going strong on this one, and looks great. CRT lifetime is variable; picture quality attenuation can begin at any time, but we’ve seen CRT’s still looking very good after 40 years or more. For older products, we often dial in a composite-video feed, to enable viewing modern video devices. CRT’s were often very hardy. While a step up from early rotating-disk mechanical televisions, the mass and weight of CRT’s eventually gave way to modern plasmas, then LCD’s; coming next: placemat/rollup screens.
Here, we diagnosed and performed a pretty simple and routine fix: some reconfig and resoldering in the audio circuit.
