Safety Precaution CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL ONLY. PRECAUTIONS DURING SERVICING 1. In addition to safety, other parts and assemblies are specified for conformance with such regulations as those applying to spurious radiation. These must also be replaced only with specified replacements.
5. When replacing a MAIN PCB in the cabinet, always be certain that all protective are installed properly such as control knobs, adjustment covers or shields, barriers, isolation resistor networks etc. 6. When servicing is required, observe the original lead dressing. Extra precaution should be given to assure correct lead dressing in the high voltage area. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in this apparatus have special safety-related characteristics.

Main (Video InterFace) board: To converter TV signals, S signals, AV signals, Y Pb/ Cb Pr/Cr signals, DVI signals and D-SUB signals to digital ones and to transmit to Control board. 3. Control board: Dealing with the digital signal for output to panel. 4. Y-Sustainer / Z-Sustainer board: (1). Receiving the signals from Control and high voltage supply.
PCB failure analysis 1. CONTROL: a. Abnormal noise on screen. b. No picture. 2. MAIN (VIDEO): a. Lacking color, Bad color scale. b. No voice. c. No picture but with signals output, OSD and back light. d. Abnormal noise on screen. 3. POWER: No picture, no power output. 4. Z - Sustainer: a. No picture. b. Color not enough. c. Flash on screen. 5. Y - Sustainer: Darker picture with signals. 6. Audio Bard: a. No voice. (Make sure status: Mute / Internal, External speaker) b. Noise 7.
Basic operation of Plasma Display 1. After turning on power switch, power board sends 5Vst-by Volt to Micro Processor IC waiting for ON signals from Key Switch or Remote Receiver. 2. When the ON signal from Key Switch or Remote Receiver is detected, Micro Processor will send ON Control signals to Power. Then Power sends (5Vsc, 9Vsc, 24V and RLY ON, Vs ON) to PCBs working. This time VIF will send signals to display back light, OSD on the panel and start to search available signal sources.

Product Specification of PDP Module 0. Warnings and Cautions 9 WARNING indicates hazards that may lead to death or injury if ignored. 9 CAUTION indicates hazards that may lead to injury or damage to property if ignored. WARNING 1) This product uses a high voltage (450 V max.). Do not touch the circuitry of this product with your hands when power is supplied to the product or immediately after turning off the power. Be sure to confirm that the voltage is dropped to a sufficiently low level.
Product Specification of PDP Module CAUTION General 1) Do not place this product in a location that is subject to heavy vibration, or on an unstable surface such as an inclined surface. The product may fall off or fall over, causing injuries. 2) When moving the product, be sure to turn off the power and disconnect all the cables. While moving the product, watch your step. The product may be dropped or fall, leading to injuries of electric shock.
Product Specification of PDP Module USE 1) Because this product uses a high voltage, connecting or disconnecting the connectors while power is supplied to the product may cause malfunctioning. Never connect or disconnect the connectors while the power is on. Immediately after power has been turned off, a residual voltage remains in the product. Be sure to confirm that the voltage has dropped to a sufficiently low level. 2) Watching the display for a long time can tire the eyes.
Product Specification of PDP Module 1. GENERAL DESCRIPTION DESCRIPTION The PDP42V6#### is a 42-inch 16:9 color plasma display module with resolution of 852(H) × 480(V) pixels.
