Your user manual will have the flashing light code structure indicating the fault that caused the shutdown there is no thermal fuse in your TV
projection TV`s have integrated protection circuits
built into the circuit design, these circuits turn the
power off automatically when a fault has bin detected this
is in order to prevent a more costly repair, these circuits monitor
power supply , vertical and horizontal deflection
over voltage, or x ray, and also faults with convergence circuits.
Diagnosing these faults require test equipment and a good knowledge of
electronic repair techniques, and also a repair manual.
