Sylvania Television Set Chassis Model Number 19C527- Home Forums Galleries Vintage Television Gallery Vintage Video Galleries E-mail   Vintage Sylvania Television Set Chassis Model Number 19C527-   Sylvania Television Set Information   Sylvania 19 inch superset television chassis model 19C527-. The set model number is missing. Manufactured in 1985. Same as the Sylvania Model 28025506. Sylvania offered these same styles in different sizes and different features. There were styles with the analog clicker tuner, and non remote version with the digital tuner which had a push in/out volume knob. These were quite a popular set back then and pretty much becoming extinct now.     Common Problems: Tuner problems. If you have one with tuner problems you will notice when watching, the channel will flicker in and out with an interference with the sound too. I do believe with the old set we had up till 1993, the tuner went completely out with a fuzz and static sound.   Pictures
