No. A PlayStation 3 console can be hooked up to pretty much any TV. Most TVs from the early to mid 90s and on have the tri-audio/visual cable hookups that consist of yellow, white and red wires. The white and red are audio signals and the yellow is your video signal. The PlayStation 3 comes stock with these component hookups. If you have an older TV however that uses a cable adapter, you can buy an A/V cable connector that should be adaptable to the PS3. Check online, just go to a search engine. You can probably also find more in-depth solutions to your query at the PlayStation website.
