Don't know the brand but sounds like it tries to start and detects a short circuit and shuts down as described while the process then repeats. This is a common symptom of most t.v's with a possible shorted line flyback transformer and/or transistor and requires investigation within the line output stage. Unless you are familiar with such circuitry I would contact a dealer for service due to voltages associated with the transformer of 25000 volts.
