Question about RCA P56940 56" Rear Projection Television
Ihvt is bad replace it its the high voltage transformer that powers the unit
Posted on Dec 13, 2008
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.
