  32. V. Trouble Shooting TROUBLE SHOOTING

  33. V. Trouble Shooting CONTENTS • Power Trouble Shooting • Analog Part • Digital Part • Sound Part • Flow Chart & Waveforms • White Balance • Access Service Mode

  34. Check List for Initial Operation -. Power cord into the set -. Power switches on -. You can hear the SMPS relay * If you can’t hear the relay, check if you have 5V standby -. Logic Board LED is on * If Logic Board LED doesn’t blink -> Check if the Logic Board LED is on, when 24p power cable is not connected. -. Video on * If no video, check the LVDS cable And LVDS clk/data line

  35. Inform to change the Assembly -. Check the side-label version of the set (important) -. Order parts according to the side-label version -. If you change a part check if there are any service-bulletins for potential settings that need to be changed in the factory menu. Inform about error messages -. If the set is connected to the network and the software is old, the below message will pop up. “ version XXXXX is available, upgrade?” -. Select OK, and you can update your PDP TV’s firmware.

  36. V. Trouble Shooting 1. The sets power is composed of a power board and a main board (small power) 2. Check the connectors between power board and main board 3. Check the main boards power outputs 4. When you check main board power(small power IC), There are two types of power IC. One is PWM type, another is regulator type. PWM type should check after inductor. Regulator type should be checked on the output pin. 5. Check each voltage Check After Inductor Check On Pin Regulator Type 2 PWM Type 1 A) Power Trouble Shooting

  37. V. Trouble Shooting A) Power Trouble Shooting

  38. V. Trouble Shooting Gray Level H-sync 16 Gray Wave Form B) Analog Part 1.It is easy to check analog video signal than digital video signal 2.Use reference signal input ( EX. 16 Gray) 3.Check Signal Level and sync 4.Check Signal path until input of Video decoder ( Tuner → Video Decoder, AV Connecter → Video Decoder) 16 Gray Patten

  39. V. Trouble Shooting B) Analog Part

  40. V. Trouble Shooting

  41. V. Trouble Shooting 1 Period(50Hz) 1 Period(13.5MHz) 1 Period(15.63kHz) V-Sync Clock H-Sync C) Digital Part 1.It is difficult to check digital video signal because of too fast and small signal 2.Check digital video signal, Use H-sync, V-sync and Clock for basic 3.Each digital video ICs connected with data line, H-sync, V-sync and Clock line 4.Check H-sync period, V-sync period, Clock period 5.If period is out of spec, Change the IC This example is Normal PAL TV signal Sync and Clock

  42. V. Trouble Shooting C) Digital Part
