Precaution 1. Precaution To avoid possible damage, electric shocks or exposure to radiation, follow the instructions below with regard to safety, installation, service and ESD. 1-1 Safety Precautions 1. Make sure all protective devices are properly installed including non-metallic handles and compartment covers when installing or re-installing the chassis or chassis assemblies. Make sure that no gaps exist between the cabinets for children to insert their fingers in to prevent children from receiving electric shocks. Gaps mentioned above include ventilation holes between the PDP module and the cabinet mask, and the improper installation of the rear cabinet. Errors may occur when the resistance is below 1.0 or over 5.2 . In these cases, make sure that the device is repaired before sending it back to the customer. 3. Check for Electricity Leakage (Figure 1-1) Warning: Do not use an insulated transformer for checking the leakage. Use only those current leakage testers or mirroring systems that comply with ANSIC 101.1 and the Underwriter Laboratory's specifications (UL1410, 59.7). 5. Warning for Engineering Changes: Never make any changes or additions to the circuit design or the internal part for this product. Ex: Do not add any audio or video accessory connectors. This might cause physical damage. Furthermore, any changes or additions to the original design/engineering will invalidate the warranty. Warning - Hot Chassis: Some TV chassis are directly connected to one end of the AC power cord for electrical reasons. Without insulated transformers, the product can only be repaired safely when the chassis is connected to the earth end of the AC power source. To make sure the AC power cord is properly connected, follow the instructions below. Use the voltmeter to measure the voltage between the chassis and the earth ground. If the measurement is over 1.0V, unplug the AC power cord and change the polarity before reinserting it. Measure the voltage between the chassis and the ground again. 7. Some TV chassis are shipped with an additional secondary grounding system. The secondary system is adjacent to the AC power line. These two grounding systems are separated in the circuit using an unbreakable/unchangeable insulation material. When any parts, material or wiring appear overheated or damaged, replace them with new immediately. When any damage or overheating is detected, correct this immediately and make a regular check of possible errors. 2. 6. DEVICE UNDER TEST TEST ALL EXPOSED METAL SURFACES 2-WIRE CORD ALSO TEST WITH PLUG REVERSED (USING AC ADAPTER PLUG AS REQUIRED) LEAKAGE CURRENT TESTER (READING SHOULD NOT BE ABOVE 0.5mA) 8. EARTH GROUND Fig. 1-1 AC Leakage Test 4. A high voltage is maintained within the specified limits using safety parts, calibration and tolerances. When voltage exceeds the specified limits, check each special part. 9. Check for the original shape of the lead, especially that of the antenna wiring, any sharp edges, the

For VS and VA outputs, a LLC converter has been used. For the other outputs, a Flyback converter has been used. LOGIC Board The logic circuit consists of a Logic Main Board and an Address Buffer Board. The Logic Main Board decodes the video signal encoded by the Video Board, outputs the ADDRESS data signal for each pattern and generates X and Y drive signals. The Address Buffer Board buffers and transfers the ADDRESS data output signal using TCP IC. - LVDS with built-in video signal processing (W/L, error diffusion, APC, FCR, etc.) applied and 1 ASIC chip. - Outputs the address Drive IC control and data signals to the Buffer Board. - Outputs the control signal for the X and Y Drive Boards. - Monitors major drive voltages (Micom Circuit Block); detects if a surge voltage has been applied and protects the Drive Circuit. - Temperature Adaptive Operating Mode (Low Temperature/Room Temperature/High Temperature); Discharge optimization for each temperature level. X-MAIN Board Connects to the X terminal block, 1) provides maintaining voltage waveform (including ERC), and 2) maintains the Ve bias in the Scan section. Y-MAIN Board Connects to the Y terminal block, 1) provides maintaining voltage waveform (including ERC), 2) provides Y Rising, Falling Ramp waveforms, and 3) maintains the Vscan bias. Address Buffer Board It delivers the data signal and control signal to the TCP.

Troubleshooting 4. Troubleshooting 4-1 Troubleshooting 4-1-1 First Checklist for Troubleshooting 1. Check the various cable connections first. - Check to see if there is a burnt or damaged cable. - Check to see if there is a disconnected or loose cable connection. - Check to see if the cables are connected according to the connection diagram. 2. Check the power input to the Main Board. 3. Check the voltage in and out between the SMPS Main Board, between the SMPS X, Y Main Board, and between the Logic Boards. Samsung Electronics 4-1 Troubleshooting 4-1-2 Checkpoints by Error Mode No Power Symptom - The LEDs on the front panel do not work when connecting the power cord. - The SMPS relay does not work when connecting the power cord. - The unit appears to be dead. The SMPS relay or the LEDs on the front panel does not work when connecting the power cord if the cables are improperly connected or the Main Board or SMPS is not functioning. In this case, check the following: - Check the internal cable connection. Major Checklist - Check the fuses. - Check the output voltage of the SMPS. - Replace the Main Board. Troubleshooting Procedures Is the AC IN socket connector and the Main SMPS CN800 connected? Yes Is the Fuse (F801S) of the Main SMPS Power Input Part blown? Yes CN801 Check the STD5V vOLTAGE Check PS_ON voltage if it is 0V Yes Replace the Main Board No The AC IN socket connector and the Main SMPS CN800 connected Yes Replace Fuse (F801S) No Replace the Main SMPS 4-2 Samsung Electronics Troubleshooting When the unit is repeatedly turning on and off Symptom - The SMPS relay is repeatedly turning on and off. In general, the SMPS relay repeatedly turns on and off by the protection function due to a defect on a board connected to the SMPS. - Disconnect all cables from the SMPS, operate the SMPS alone and check if the SMPS works properly and if Major Checklist each voltage output is correct. - If the symptom continues even when SMPS is operated alone, replace the SMPS. - If the symptom is not observed when operating the SMPS alone, find any defective assemblies by connecting the cables one by one. Troubleshooting Procedures Does the symptom continue when connecting the power after removing CN810 from the SMPS? Yes Does the symptom continue when connecting the power after removing CN809 from the SMPS? Yes Does the symptom continue when connecting the power after removing CN807 from the SMPS? Yes Replace the SMPS No Replace the Y Main Board No Replace the X Main Board No Replace the Logic Board Caution When separating and connecting the cables such as CN810, CN809, CN808, CN807 of the Main SMPS, CN4701 of the X Main Board, and CN5707 of the Y Main Board, a spark may be generated by the electric charge of the high capacity capacitor. Therefore, wait some time after disconnecting the power cord from the unit. Samsung Electronics 4-3 Troubleshooting No Picture (When audio is normal) Symptom - Audio is normal but n
