How to Replace the Transistor on a 32-Inch RCA TV
RCA has been a popular name in household electronics since its early beginnings in 1919. RCA 32-inch color televisions are full of electronic components, including processor chips, LED's, capacitors and transistors. A transistor is an electronic component that both amplifies and switches electronic signals. Transistors commonly have three leads, or connectors. If a resistor goes bad on an RCA television, it can affect the entire unit. If this happens, the transistor should be replaced.
