Colortrak

Colortrak was a trademark used on several RCA color TVs throughout the 1970s to the 1990s. After RCA was acquired by General Electric in 1986, GE sold the RCA consumer electronics line to Thomson SA. RCA televisions with the Colortrak branding were mid-range models; in comparison to the low-end XL-100 chassis or high-end Dimensia or Colortrak 2000 chassis in consumer sets (the professional version of the Dimensia model, or versions with BNC inputs, the designation was "Lyceum TV" for a short period in the early to mid 1980s). RCA discontinued use of the Colortrak brand, replacing with the Entertainment Series designation by 2001. Some models like this with the design quirks mentioned below have also been marketed under the GE name as both RCA and GE's brand names are marketed by Thomson SA.
