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:

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.

SOURCE: TH-42PX80U JUST TURNED ITSELF OFF

The 7 blinks indicates that a failure has happened within the Y main and the upper and lower y drive panels. I recommend you taking it in to a Service center for and evaluation.

SOURCE: panasonic th-42pz77u has no picture.power light

seven blinks on this model is the SC board. it will need a new SC board and the software update for the new board. usually only authorized servicers have the software need to do the upgrade. but if you were to contact panasonic then they might be able to have it fixed for you for free since this was a defect in manufacturing. of course this depends on how long you have had the tv.

My panasonic viera lcd, model no. th-42px80u, flashes green when powered up, then a sequence of 10 red flashes. whats the problem ? joe


Before spend $$ on replacement boards, make sure anything attached to it is powered off. Unplug TV for 5mn to 15min. Plug back in and it should power on. If not leave unplugged overnight before spending on a replacement board. We have to do this 2-3 times per year when someone forgets to turn off auxiliary components (receiver, DVD, cable box, etc) first. It has always come back on.

I have a 42" Panasonic


If you remove the back panel and check on the power supply board, you will find a couple of bulged caps that need to be replaced, or just replace the power supply board.

I have a TH-42PX80U. The picture went black and the red light does NOT blink. I tried a different power cord in a different outlet and still won't turn on.


More likely to have power supply module failure, that will be the first place to look.
Most common failures in PLASMA TV are due to bad power supply module, Z and Y Sustain modules.

Panasonic TH-42PX80U won't turn on.


You are missing 15volts. If this is a new TV, it could be as simple as a plug not fully seated on the power supply. Regardless, the repair should be covered by warranty and Panasonic is one of the best when it comes to taking care of the customer. Ifd nI can be of further assistance, let me know
