Power On Operation

The power command from the power switch on the S board or the remote control receiver on the K board is provided to the Main CPU on the A board (IC1100) thru connector A1. The CPU on the A board outputs the “TV_SUB_ON” Command (3.2V) and the PANEL_STB_ON” command (3.2V).

The “TV_SUB_ON” command is provided to pin 6 of connector P7 of the power supply through pin 14 of connector A6 of the A board to develop the F_STB+15V. At this time the relays on the power supply are triggered and a “click” sound can be heard.

The F+15V from the P board is applied to several voltage regulator (IC5603, IC5401, and IC5607) on the A board.

The voltage outputs from these ICs are called SUB5V, SUB9V, SUB3.3V, SUB1.8V, SUB1.3V, and BT30V. They used by various circuits on the A board.

To avoid catastrophic failures, they are monitored by an SOS Detect circuit (IC5480) for over-voltage and over-current conditions. This SOS Detect circuit is controlled by the TV_SUB_ON command from the Main CPU (IC1100).

Any abnormalities of the SUB5V, SUB9V, or BT30V triggers the SOS circuit. The TV shuts down and the power LED blinks 10 times.

The “PANEL_STB_ON” is used to turn on the 3.3V regulator (IC9004) on the A board. The output voltage is applied to the “Panel” CPU on the A board (Formerly located in the D board).

The Panel CPU on the A board outputs the “PANEL_MAIN_ON” Command (3.2V) to pin 11 of connector P25 on the P board.

The PANEL MAIN ON command turns on the power supply circuit that outputs the Vsus, Vda, 15V, and 5V.

This technology reduces the size of subpixels, thereby increasing the overall pixel count and improving the display's ability to reproduce finer detail. As a result, users can enjoy a rich and immersive visual experience with vibrant colors and excellent contrast across all lighting conditions.

The TC-P46S1, with a 46-inch screen, the TC-P50S1 at 50 inches, and the TC-P54S1 at 54 inches, cater to various room sizes and viewing preferences, making them versatile options for different home setups. The displays support Full HD 1080p resolution, which guarantees sharp and clear imagery, whether it’s for watching movies, playing video games, or streaming content.

Another standout feature is the Viera Image Viewer, which allows users to view their photos and videos directly on the television using SD memory cards. This feature enhances the television's utility beyond traditional broadcasting, making it a fantastic centerpiece for family gatherings and social events.

These models also include a 600Hz Sub-field Drive technology, which improves motion clarity, reducing blur during fast-paced scenes such as sports or action movies. This technology ensures that viewers can enjoy a smooth cinematic experience without sacrificing detail.

Moreover, the TC-P46S1, TC-P50S1, and TC-P54S1 are designed with energy efficiency in mind, given the increasing emphasis on environmentally friendly electronics. They are equipped with energy-saving features that help reduce power consumption without compromising performance.
