SOURCE: PANASONIC TH-42PD60U

I had a similar problem where my TH-42PX60 would turn on but all controls were disabled. I could not change channel, input, volume or anything other than turning the TV on and off. I called customer support and they directed me to this site: http://www.pasctraining.panasonic.com/specialapplications/productfirmwaredownloads/downloads1.asp to download a firmware update onto an SD Card. I inserted the SD card into the slot in my TV and powered it on. The update took about 3 minutes and I haven't had a problem since.
This is a link to the instructions to install the update:

SOURCE: (panasonic TH-42PZ77U plasma) the tv will power on

in protective mode the tv does not turn on and light is blinking, typically we must proceed by elimination as some faulty sections are preventing the tv to switch on. unplug the output power connectors from the power supply until the latter stop clicking. if it is still clicking after every of the output rail have been disconnected, then the power supply itself is faulty.

hope this helps!

SOURCE: Panasonic Plasma TH-42PZ77U Power Light Flashing 7x

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.
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.

I have a 56inch panasonic Viera LED TV. it turns on and the sound works fine, and the screen lights up but it is a white blank screen with no picture. Suggestions?


Does it display channel numbers or other pictures when you press menu or other tools? If so, it's a problem with the TV's video inputs. If not, it's something wrong with the projection hardware, matrix, or power supply. Failing that, I recommend contacting Panasonic's support center, and keep any information you have on buying the TV handy. Good luck!

Picture and sound go off and power indicator blinks eight times. TV will not turn off or back on. Disconnecting power for a few seconds restores the picture and sound for a time, but then it repeats.


The TV might be telling you that there's something wrong with the power (wrong or excessive voltage, for instance). Please test the TV at someone else's house to rule out electricity problems at your house. If the TV still shuts off, then there should be something wrong with its logic board or power circuits, and you should call a technician to inspect it.
