The malfunctioning part can be identified by the number of blinks of the power light.ĥ blinks 5v SOS P-Board / D-Board / DN-Boardħ blinks Driver SOS 2 SC-Board / SU-Board / SD-BoardĨ blinks Driver SOS 3 SS-Board / SS2-Boardĩ blinks Panel Config. The power LED requires the replacement of the Aboard.Īll Panasonic Plasma TVs feature a protection circuit that will force the TV to shut down in case of a problem. Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. The audio output circuit is located the Aboard. Nine blinks of the power LED are due to a short circuit in the audio output circuit (s) of the unit.

The detection input pins of the MPU, IC1100, monitor for their presence. The A board is responsible for five, seven, or eight blinks of the power LED. A short or open circuit on the A board may also be responsible for their absence.įive, Seven, or Eight Time Blinking: 5 Blinks, 7 Blinks, 8 Blinks Error The MPU IC1100 monitors for their presence when the unit is connected to AC Power. The DTV9V and SUB_5V sources are produced on the AP board. The AP board is responsible for four or six blinks of the power LED. An over-current condition may be due to a short circuit located in the AP board, Aboard, or the LCD panel.įour or Six-Time Blinking: 4 Blinks, 6 Blinks Error An over-voltage condition is definitely a defect of the AP board. Therefore the use of an ohmmeter and a peak-hold voltmeter is required to determine the cause of the shutdown.

Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The inverter board is not to be repaired in One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel.
