Frequently Asked Questions
How can I tell how old a TV is?
Look at the display type: CRT (1920s–2000s), plasma (2000s–2010s), LCD (2000s–today), LED-LCD (2010s–today), OLED (2020s–today). Check the form factor: console wood cabinet (1950s–60s), large thick CRT (1970s–90s), flat panel (2000s onward). See if it's a smart TV (2010s onward) or check for specific input types (antenna jack, RCA, HDMI generations).
What is the difference between LCD and LED TVs?
All modern flat-panel TVs are technically LCD (Liquid Crystal Display). "LED TV" refers to the backlighting method: LED-backlit uses LED lights behind the LCD panel (standard since mid-2010s), while older LCD used CCFL backlighting. OLED TVs don't use backlighting; each pixel emits its own light.
When did plasma TVs become popular?
Plasma TVs were introduced in the 2000s and were popular for premium large-screen applications through the 2010s. They've largely disappeared from the market due to higher cost and power consumption compared to LED-LCD.
When did smart TVs become common?
Smart TVs with built-in streaming apps emerged in the early 2010s but remained optional. By the mid-2010s, they became standard on most new TVs sold. By 2020, non-smart TVs were rare in retail.
Can Decode My Item decode TV serial numbers?
TV model numbers often encode manufacturing date. Use the Serial Number Decoder tool to identify TV age if the brand/model format is supported. Some brands encode date in model numbers; others use separate date stickers.
