  16. Ⅶ. How to Check PDP TV Problem • PDP TV Power On Sequence 1. PS_ON Signal On (MainBoard → SMPS ) 2. SMPS Works ( Low Voltage Block) 4. VS_ON Signal On ( Logic Board → SMPS ) 3. Logic Board Works When VS_ON signal does not occur Vs voltage is not supplied, and a “No Screen" phenomenon occurs. 5. SMPS Vs, Va Voltage On 6. DC/DC Block Works ( Vscan, Ve ) Display

  17. X-BUFFER Y-MAIN Ⅶ. How to Check PDP TV Problem ■ DrivingBlock Diagram

  18. Ⅶ. How to Check PDP TV Problem • Diagnosis ■ Things to check first if there is trouble 1) Check the cable connection part 2) Check LOGIC LED operating status - Normal operation: LED blink once per 0.5 second - Driving Board Problem (DRV Reset) : LED ON for 5 seconds → LED Off for 2 seconds - Logic Board Problem: LED blink once per 8 seconds Repeat… Repeat... Repeat...

  19. Ⅶ. How to Check PDP TV Problem 3) Check SMPS voltage - Check Low Voltage Block(Standby 5V , D5V , D3.3V) and High Voltage Block(Vs, Va, etc.) 4) Check the power input part of the main board 5) Check the power input part of the logic board 6) Check the power input part of the driving board and drive element damage by a fire availability - Check FET , IGTB Short - Check Scan IC OUT_L ↔ OUT_H Short 7) Check Address Buffer fuse, MLCC, and resistance
