Re: no power

The P56940 uses the PTK195 series chassis. The most common reason for that chassis not running is a shorted flyback (high voltage) tansformer. Sometimes a shorted flyback transformer will also cause the horizontal output transistor to short, and then the power supply will "chirp" when plugged in. The set should be serviced by a qualified tech familiar with the 195 series chassis.
