Vintage 1983 Samsung CT-333KA 13” CRT TV Woodgrain Retro Gaming Tested and working It's missing the 2nd knob. I'm not sure how to turn the TV on and off. I just unplug it to turn off. I think you either pull or push the volume button, but it doesn't work to turn on and off, but the volume works and is adjustable. The volume button is sensitive to touch. No attenaa.
