Question about Panasonic TH-42PD60U Television

1 Answer

Panasonic Plasma TV model TH42PD60U Shuts off power led flashes 7x

This TV is about a year and half old. The problem has become more frequent. The TV will work fine and then just go out completely. The power indicator led flashes 7x then pauses and then flashes 7x again and repeats. Turning off the power button will reset it and the TV will turn on again and works perfectly. Sometimes the problem will reoccur after a few seconds and sometimes hours. Can't smell anything getting hot, like resisters frying.
I've tried disconnecting the power supply cord from the back of the TV and reconnecting and also have tried plugging it into a different wall outlet. no change.

    Did the software correct this problem?
    I was told it was a D-board.

    I have the same problem. When it goes off randomly, you can kick start it again by pressing the on switch till the blinking stops. When it stops, let it go till it clicks on. Keep trying till it goes on.

    We did have a service company check out this problem and mentioned that it would not be worth fixing. Too expensive he said! If this isn't true, please inform.

I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!

Red light blinks 9 times on Panasonic TH-42PZ77U


hello, panasonic plasmas have a safety shut down circut to protect the main panel when a short is present or internal circut panel is non functional some info i found in the service manual for 10th generation plasma
if your tv is still under warantee take advantage of the pany free service other wise it is a matter of exchanging the defective board then you will need electronic skills for this repair if you plan to do it yourself. it would be wise to have a skilled tech check it out and give you a estimate there are some techs that will come out and check it for free and give you a repair price.

here are some repair manual tips for blinking panasonic .. i didnt find 9 blinks on this manual i may be using a different manual but these are panasonic plasma blinking fault tips for 10th gen
becuase all models have different blinking codes you may need the model specific service manual

for 10th gen model some models 2008,2007,

8 Blinks SOS:
Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.

9 blinks panel config sos

10 Blinks SOS:
The SUB5V and DT9V sources created on the A board are monitored by IC1100. If they are not present at pin 30 and 34, the MPU shuts down the unit. The power LED blinks 10 times.

10 Blinks SOS:
The F_STB_15V of the P board, as well as the derived SUB5V and DT9V sources are monitored on the A board for excessive current. If a short circuit is developed in one of the supplied lines, pin 114 of IC1100 receives a high. The SUB5V and DT9V lines are also monitored for excessive voltage. When an over-voltage condition is detected, a high is also output to pin 114 of IC1100. The DT9V is provided to a DC/DC converter to create the BT30V for the tuner. If the BT30V becomes excessive, a high is output to pin 114 of IC1100. A high at pin 114 of IC1100 causes the unit to shutdown and the power LED to blink 10 times.

hope this helps..

I have a panasonic plasma th-42px60 tv for about a year and a half now when i changed the fuse in the plug the power led light is flashing but there is no picture


Panasonic shows multiple board replacement in sequence of boards that may be the problem. they start with the PA board as the most likely culprit start with that. how ever there may be 6 other boards that can cause a 10 flash code.
the PA board part # is TXNPA1BJTUJ.

Panasonic Th37PE30 Viera plasma stopped working


here is a complete list of all codes for panasonic tv's rgeardless of model if its panasonic it is these codes

1 Blink SOS: This shutdown operation is usually caused by a lack of communication between the A and the D boards.
1 Blink SOS: This shutdown operation may be caused by the improper connection of a SS board connector to the panel.
2 Blinks SOS: Pin 87 of the MPU IC9003 monitors the 15V line. During normal operation, the transistors Q9053 and Q9054 output a high to pin 87. If the 15V line is missing or shorted, a low is provided to pin 87. As a result, the unit shuts down and the power LED blinks 2 times.
3 Blinks SOS: IC9807 is a 3.3V regulator located on the D board. Its output is monitored by IC9003. If the 3.3V is not present at pin 86, the MPU shuts down the unit. The power LED blinks 3 times.
5 Blinks SOS: Pin 85 of the MPU IC9003 monitors the 5V line. During normal operation, the transistors Q9051 and Q9052 output a high to pin 85. If the 5V line is missing or shorted, a low is provided to pin 85. As a result, the unit shuts down and the power LED blinks 5 times.
6 Blinks SOS: Pin 90 of the MPU IC9003 monitors the status of the SC board. During normal operation, the transistor Q6581 and IC6581 output a low to pin 90. If the SC board becomes defective, a high is provided to pin 90. As a result, the unit shuts down and the power LED blinks 6
6 Blinks SOS: 6 blinks of the power LED may also be obtained from pin 3 of IC9003, the DRV_RESET input. The D board provides the 5V source needed to power the C boards. On the C2 board, the 5V is routed back to the D board via connector C20/C10, C11/D31 causing pin 3 of IC9003 to be high. If 5V is not routed back to the D board, pin 3 of IC9003 goes low. The set goes into shutdown mode and the power LED emits 6 blinks.
7 Blinks SOS: Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times.
8 Blinks SOS: Pin 91 of the MPU IC9003 monitors the status of the SS board. During normal operation, pin 8 of connector SS23 outputs a low to pin 91. If the SS board becomes defective, a high is provided to pin 91. As a result, the unit shuts down and the power LED blinks 8 times.
10 Blinks SOS: The SUB5V and DT9V sources created on the A board are monitored by IC1100. If they are not present at pin 30 and 34, the MPU shuts down the unit. The power LED blinks 10 times.
