Page 15: Sub-Field
Sub-field https://www.werbemousepads.de/pdf/ A number of sub-fields overlap to depict the image in each frame. Panasonic technology detects movement in the image and reflects it in each individual sub- field to achieve smooth playback with minimal blurring. What's Sub-field? Plasma TVs express a single frame of an image by using multiple images, each having a different gradation. -

Page 30: Sub-Voltages Distribution
Sub-Voltages Distribution https://www.werbemousepads.de/pdf/ On previous generations these voltages were present for approximately 15 seconds after connecting the TV to the AC line. This does not apply to this year’s models. These voltages are called sub-voltages and they are only used by the A board. The sub-voltages are developed when the power is turned on. -
Page 31: Blinks Condition Troubleshooting
10 blinks Condition Troubleshooting https://www.werbemousepads.de/pdf/ Since the Sub voltages are only present after the power has been turned on, there will not be a 10 blinks condition at plug-in for the 2009 models. These 3 conditions can cause the TV to shutdown and the power LED to blink 10 times Missing/Shorted F_STB_15V, SUB9V, SUB5V, and BT30V Wrong diagnostic by the A board Note:... -
Page 32: Sos Detect (Shutdown)
https://www.werbemousepads.de/pdf/ SOS Detect (Shutdown) When an abnormality occurs in the unit, the “SOS Detect” circuit is triggered and the TV shuts down. The power LED on the front panel will flash a pattern indicating the circuit that has failed. If the power LED continues to blink even after the TV is unplugged, press and hold the power switch on the TV for a few seconds until the LED turns off. -

65. As a result, the unit shuts down and the power LED blinks 6 times. The TC-P42X1 series monitors the sustain board output. This signal is connected to the recovery circuit in the SC board. Any abnormality on the sustain board will trigger the 6 blinks code. -
Page 39: System Pmu Sos Detect
System MPU SOS Detect https://www.werbemousepads.de/pdf/ 10 Blinks SOS: IC5401 generates the SUB9V, IC5607 generates the SUB5V, and IC5480 generates the BT30V. The SUB9V, BT30V, and SUB5V from these ICs are monitored by IC1100. Any abnormality on these voltages (Including the F_STB15V), triggers the shutdown circuit and the MPU shuts down the unit. -

Glossary https://www.werbemousepads.de/pdf/ Resolution Resolution is a combination of values that express the quality of displayed images. A display's resolution is indicated by the number of dots in the horizontal and vertical directions of the screen, such as 1024 x 768 dots. Higher values indicate clearer, sharper image reproduction. The larger the screen size, the higher the required resolution. - Page 75 Glossary https://www.werbemousepads.de/pdf/ THX is a trade name of a high-fidelity sound reproduction standard for movie theaters, screening rooms, home theaters, computer speakers, gaming consoles, and car audio systems. THX stands for Tomlinson Holman's eXperiment. The THX system is not a recording technology, and it does not specify a sound recording format: all sound formats, whether digital (Dolby Digital, SDDS) or analog (Dolby Stereo, Ultra-Stereo), can be "shown in THX."...
