Slide #29 Sub-Voltages[...]

Slide #30 Sub-Voltages Distribution On previous generations these voltages were present for approximately 15 seconds after connecting the TV to the AC line. This does not apply to this year’s models. These voltages are called sub-voltages and they are only used by the A board. The sub-voltages are developed wh en the power is turned on. The F+15V[...]

Slide #31 10 blinks Condition Troubleshooting 1. Missing/Shorted F_STB_15V, SUB9V, SUB5V, and BT30 V 2. Wrong diagnostic by the A board Since the Sub voltages are only present after the power has been turned on, there will not be a 10 blinks condition at plug-in for the 2009 models. These 3 conditions can cause the TV t o shutdow n and the power LE[...]

Slide #32 SOS Detect (Shutdown) When an abnormality occ urs in the unit, the “SOS Detect” c ircuit is trigger ed and the TV shuts down.

Slide #37 Panel MPU SOS Detect • Protection circuits are incorporated in the unit to prevent the failure of a si ngle circuit or component from creating catastrophic damage. • A shutdown condition occurs when there is an over voltage, a short or a drop in any of the voltage lines. Also the shutdown circui t is triggered when the fans are drawin[...]

Slide #38 Panel MPU SOS Detect (Continue) 4 Blinks SOS: When an over voltage condit ion of the voltage lines from the power supply occurs, pin 12 of connector P25 goes high. This high is provi ded to pin 67 of IC9003 of the A board triggering the “POWER SOS” circ uit. When this h appens, the TV shuts dow n and the power LED blinks 4 times. Prim[...]

Slide #39 System MPU SOS Detect 10 Blinks SOS: IC5401 generates the SUB9 V, IC5607 generates the SU B5V, and IC5480 generates the BT30V. The SUB9V, BT30V, and SUB5 V from these ICs are monitored by IC1100. Any abnormality on these volt ages (Including the F_STB15V), tri ggers the shutdown circuit and the MPU shuts down the unit. The power LED blin [...]

Slide #40 2 Blinks Error Code 1. Missing P15V 2. A short of the P15V 3. Wrong diagnostic by the A board These 3 conditions can cause the TV t o shutdown and the power LED to blink 2 times[...]

Slide #41 Troubleshooting 2 Blinks Error Code When troubleshooting a PDP TV that is shutting down and the power LED blinks 2 times: Find out if 15V is output at pin 1 of connector P6 of th e P board. If 15V is present, it’s likely that th e A board is defective. If no voltage is output, determine if this is caused by the P board or the boards usi[...]

Slide #42 3 Blinks/4 Blinks Error Code Since the IC (IC9805) that generates the monitored 3.3V for 3 blinks condition and the IC (IC9003) that detects this condition are both located on the A board, then the A board is the only suspect when the TV shuts down and the power LED blinks 3 times. Replace the A board. Primarily the P board causes 4 blink[...]

Slide #43 5 Blinks Error Code 1. Missing P5V 2. A short of the P5V 3. A short of the Vda line (Note: missing Vda from the P board does not cause 5 blinks) 4. Wrong diagnostic by the A board These 4 conditions can cause th e TV to shut down and the power LED to blink 5 times[...]

Slide #44 Troubleshooting a 5 Blinks Error Code When troubleshooting a PDP TV that is shutting down and the power LED blinks 5 times: Find out if pins 1 or 2 of connector P35 are shorted to ground. If shorted, possibly the panel is bad. If there is no short circuit, proceed to check the P5V line. Find out if 5V is output at pin 5 of connector P25 o[...]

Slide #45 6 Blinks Error Code (TC-P42S1) The Scan and Sustain voltages on the SC and SS boards are monitored by an SOS Detect circuit. The energy recovery circuit in the SC board is monitored by a comparator (Error detect IC16581). The output voltage is compared to 2 reference voltages derived from the P15V. If the output of this circuit drops belo[...]
