Preliminary Matters (The Fine Print)Preliminary Matters (The Fine Print)
5 Fall 2009 1080P Plasma 50PS60
Today’s sophisticated electronics are electrostatic discharge (ESD) sensitive. ESD can weaken or damage the electronics in a manner that renders them inoperative or reduces the time until their next failure. Connect an ESD wrist strap to a ground connection point or unpainted metal in the product. Alternatively, you can touch your finger repeatedly to a ground connection point or unpainted metal in the product. Before removing a replacement part from its package, touch the anti-static bag to a ground connection point or unpainted metal in the product. Handle the electronic control assembly by its edges only. When repackaging a failed electronic control assembly in an anti-static bag, observe these same precautions.

Safety & Handling Regulations
1. Check the appearance of the Replacement Panel and Circuit Boards for both physical damage and part number accuracy.
2. Check the model label. Verify model names and board model matches.
3. Check details of defective condition and history. Example: Y Board Failure, Mal-discharge on screen, etc.
1. Approximately 10 minute pre-run time is required before any adjustments are performed.
2. Refer to the Voltage Sticker inside the Panel when making adjustments on the Power Supply, Y SUS and Z SUS Boards.
Always adjust to the specified voltage level.
3. Be cautious of electric shock from the PDP module since the PDP module uses high voltage, check that the Power Supply
and Drive Circuits are completely discharged because of residual current stored before Circuit Board removal.
4. C-MOS circuits are used extensively for processing the Drive Signals and should be protected from static electricity.
5. The PDP Module must be carried by two people. Always carry vertical NOT horizontal.
6. The Plasma television should be transported vertical NOT horizontal.
7. Exercise care when making voltage and waveform checks to prevent costly short circuits from damaging the unit.
8. Be cautious of lost screws and other metal objects to prevent a possible short in the circuitry.
9. New Panels and Frames are much thinner than previous models. Be Careful with flexing these panels. Be careful with lifting Panels from a horizontal position. Damage to the Frame mounts or panel can occur.
10. New Plasma models have much thinner cabinet assemblies and mounts. Be extremely careful when moving the set around as damage can occur.

Basic Troubleshooting StepsBasic Troubleshooting Steps
Define, Localize, Isolate and Correct
•Define Look at the symptom carefully and determine what circuits could be causing the failure. Use your senses Sight, Smell, Touch and Hearing. Look for burned parts and check for possible overheated components. Capacitors will sometimes leak dielectric material and give off a distinct odor. Frequency of power supplies will change with the load, or listen for relay closing etc. Observation of the front Power LED may give some clues.
•Localize After carefully checking the symptom and determining the circuits to be checked and after giving a thorough examination using your senses the first check should always be the DC Supply Voltages to those circuits under test. Always confirm the supplies are not only the proper level but be sure they are noise free. If the supplies are missing check the resistance for possible short circuits.
•Isolate To further isolate the failure, check for the proper waveforms with the Oscilloscope to make a final determination of the failure. Look for correct Amplitude Phasing and Timing of the signals also check for the proper Duty Cycle of the signals. Sometimes “glitches” or “road bumps” will be an indication of an imminent failure.
•Correct The final step is to correct the problem. Be careful of ESD and make sure to check the DC Supplies for proper levels. Make all necessary adjustments and lastly always perform a Safety AC Leakage Test before returning the product back to the Customer.

Power Supply Basic OperationPower Supply Basic OperationAC Voltage is supplied to the SMPS Board at Connector SC101 from the AC Input assembly. Standby 5V is developed from 165V source supply (which during run measures 380V measured from the primary fuse F302). This supply is also used to generate all other voltages on the SMPS.
The STBY5V (standby) is B+ for the Sub Micon (IC701) on the SMPS and output at P814 pins 11 and 23 then sent to the Main PWB for Microprocessor (IC1) operation. AC Detect is generated on the SMPS, by rectifying a small sample of the A/C Line at D102 and associated circuitry and routed to the Sub Micon (IC701) where it outputs at pin 15 and sent to P814 pin 18 to the Main Board where it is sensed and monitored by the Main Microprocessor (IC1). The AC Det in this set works differently than most. If AC Det is missing the Microprocessor will turn off the television in about 10 seconds after turn on.This will happen each time turn on is attempted.A new feature included on the side keypad is called a Power Button which opens a ground allowing the “Key On” line of P814 Pin 24 to go high, turning off the 5V STB line defeating the Micro Processor (IC1) on the Main Board and Remote Control Operation. When the Microprocessor (IC1) on the Main Board receives an “ ON “ Command from either the Power button or the Remote IR Signal, it outputs a high called RL ON at Pin 19 of P814. This command causes the Relay Drive Circuit to close both Relays RL102 and RL103 bringing the PFC source up to full power by increasing the 165V standby to 380V run which can be read measuring voltage at Fuse F302 and F801 from “Hot” Ground. At this time the run voltages 12V, and +5V sources become active and are sent to the Main Board via P814 (12V at pins 5 and 6 and 5V at pins 9,10, and 12). The 5V detect line from the Main Board to the SMPS Board can be measured at pin 17 of P814. It is not used.The next step is for the Microprocessor (IC1) on the Main Board to output a high on M5V ON Line to the SMPS at P814 Pin 21 which is sensed by the Sub Micon (IC701) turning on the M5V line and output at P811 and P812 pins 9 and 10 to the Y and Z SUS boards and P813 pins 1~4 to the Control board. Full Power occurs when the Microprocessor (IC1) on the Main Board brings the VS-ON line high at Pin 20 of P814 of the SMPS Board. VS-ON is routed to the Sub Micon (IC701) which turns on the 17V Audio, VA, and the VS supplies. VA and VS output at P811 to the Y-SUS board and P812 to the Z-SUS board. (VA pins 6 and 7 and VS pins 1 and 2 of either connector) the 17V Audio supply outputs to the Main board at P814 pins 1 and 2.AUTO GND Pin 22 of P814: This pin is grounded on the Main board. When it is grounded, the Sub Micon IC701 works in the normal mode. Meaning it turns on the power supply via commands sent from the Main board. When this pin is floated (opened), it pulls up and turns the Sub Micon IC701 on in the Auto mode. In this state, the Sub Micon turns on the power supply in stages automatically. A load is necessary to regulate the 17V with the SMPS disconnected. This is a good test if the Main board is suspect.

Using two 100 Watt light bulbs, attach one end to Vs and the other end to ground. Apply AC to SC101. If the light bulbs turn on and VS is the correct voltage, allow the SMPS to run for several minutes to be sure it will operate under load. If this test is successful and all other voltages are generated, you can be fairly assured the power supply is OK. Note: To be 100% sure, you would need to read the current handling capabilities of each power supply listed on the silk screen on the SMPS and place each supply voltage under the appropriate load.

50PS60 Power Supply TroubleshootingUsing two 100 Watt light bulbs, attach one end to Vs and the other end to ground. Apply AC to SC101. If the light bulbs turn on and VS is the correct voltage, allow the SMPS to run for several minutes to be sure it will operate under load. If this test is successful and all other voltages are generated, you can be fairly assured the power supply is OK. Note: To be 100% sure, you would need to read the current handling capabilities of each power supply listed on the silk screen on the SMPS and place each supply voltage under the appropriate load.
This Power Supply can be powered on sequentially for understanding of the operation and for troubleshooting purposes. When the supply is operational in its normal state the Auto Ground line at Pin 22 of P814 is held to ground by the Main Board.When the Power Button is in the off state the Standby 5V Supply will be at 0v, the Key On Line at Pin 24 will be 4.3V. When the Power Button is pressed on, the Key On Line is grounded which allows the 5V Standby to go to 5V.
46
(A) Grounding both the Auto Gnd and the Key On Lines will allow the supply to be powered up one section at a time. (B) Add a 100Ω ¼ watt resistor from 5V Standby to RL_ON and the 12V and 5V Run Lines will become active. (C) Add a 100Ω ¼ watt resistor from 5V Standby to M5V_ON to make the Main 5V Line operational. (D) Add a 100Ω ¼ watt resistor from 5V Standby to Vs_On to make the 17V, Va and Vs lines operational. (See note at top)
Note: Placing the two 100 Watt light bulbs from Vs to Ground will assure the power supply will regulate with a load and that the 17V will be stable. Without out this load, the 17V will pulsate up and down.

3) SET-UP ADJUSTMENT VR602:Adjust VR602 while observing area (A) and set the flat portion to10uSec ± 5uSec. While observing only the peak of the waveform,turn the pot CW which will cause the peak to dome to the left of the flat portion. CCW will cause the peak to decrease in amplitude. Turn CW until the dome appears, then back off CCW.
4) SET-DOWN ADJUSTMENT VR601:Adjust VR601 while observing area (B) and set to 160uSec ± 5uSec.
1) Pre-Heat unit for at least 10 Minutes before making adjustments.Vs, Va, -Vy and VSC adjustments should be completed.
2) Place unit into White Wash from the Customer’s Menu for all adjustments.

PURPOSE: To show the timing between Y-SUS and Z-SUS
From the Waveform it can be seen that the timing of the Z-SUS must align to the Y-SUS for the panel to work correctly.
If the timing is out of sync, the Control board is at fault.
Note: While making adjustments to the Ramp Up and/or Rame Down portion of the Y-Drive signal, the Control board makes the same adjustments to the Z-SUS waveform.

PREPARATION:
1) The Power Supply must be working normally under Light Bulb test.
2) Leave the Light Bulbs in place for the following test.
3) Jump the 17V from pin 1 or pin 2 P814 to the Z-SUS connector P100 1~5. (See note below)
4) Place the Scope on the Z-SUSwaveform Test Point FL103.
5) Confirm there is an Output from the Z-SUS PWB
(approximate 230V p/p in this test)
This test confirms that the Power Supply,Control Board and Z-SUS boards are all working OK.
Light bulbs must remain connected to the Vs from the
Power Supply to Gnd.
Failure to do so, will cause the 17V to fluxuate and cause the

Complete testing of the SMPS requires that you load VS with 2 100 watt light bulbs with P811 and P812 unplugged to verify it is functioning correctly.
TIP: If A/C DET is low or missing, Remove AC Det (pin 28) out of P814 and jump it to any pin carrying 5V STBY. Then reapply power to the unit. If the TV now stays on, suspect a defective SMPS.
