Transistor is usually constructed using semiconductor elements. Semiconductor elements refers to partial conductors. They are neither full nor non conductors. that semiconductor elements may be called as transistor elements
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail

Impossible to give a specific answer without more information. Is it a BJT or a FET? Most general answer is you first have to understand the circuit using the transistor and what it's supposed to do. Then, 1. Check that the power supply voltages are correct. 2. Check that the DC biases are correct. 3. Check that the input signal is correct. 4. Check the output. But you have to know in advance what to expect.
Open up the case and replace the B772 transistor on the circuit board.

Depends on the material it's constructed from, the application for which it's being used and the atmospherics to which it's exposed. I have printed circuit boards from the very first model of an RCA transistor radio made in 1957 and the circuit board as well as the electronics still work.

well either the radio control is not sending the signal or you burnt a transistor in the circuit board. that means you have to find the faulty transistor and switch it for another identical one.
Transistor are DC output, Triac are AC output.
A transistor does not act as an amplifier. It is used as a component in an amplifier circuit.
This mechanism is how a transistor works.
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
A switch, switching transistor, or circuit breaker usually does.
Selection and setting of a transistor's operating pointto meet circuit functional requirements.
