This set can accept the current standard resolution NTSC TV transmissions, DVD, VHS, and Camcorder video signals, convert them, and display them on a high-resolution TV screen. An external set top converter box is necessary to receive Digital TV programs. Related Models Circuitry Information The power consumption and self-diagnostics remain the same as other Sony TVs. This set's change to high-resolution video results in circuitry changes to the video processing, horizontal frequency (fixed at 33.75kHz), and high voltage generation.
