I would guess a power board failure. The blinking light is an error code.

We had a Pioneer that did the same thing. We called a Pioneer Service Center. It appears there was a recall on the Power Supply. They fixed it in our home at not charge.

Most of the time when this happens it is the ysus board, that noise you heard was a capacitor popping. Another board runs about $175 and thats if you do it your self. A shop will most likely charge around 500-600, hope this helps, you could also try contacting panasonic and trying to get past the tech and onto casemanagement where you might get somewhere with an out of warranty fix.

SOURCE: panasonic viera tv won't turn on. Power light

hello, you have a either your su, sd or sc boards fualty and it is a driver sos1 thats what the manual reads the best thing to do if your not electronically inclined or able to fix it is to get a service manual and make sure it is for your specific model and size you will find what the 7 blink codes mean, on my side i have a 42 in pana the service manual for this set and your is similar so since it is not the same model i cant tell you exactly what the truoble is but your best bet is to find a service manual find the 7 blink fualt then without getting ripped off you will know what the service man needs to do if you dont know or cant replace the parts yourself that is besides having to download firmware from your computer to a sd card and update your set but you need to solve the blinking code first it may solve the entire issue. the tv should come on when you resolve the blink codes or replace the fualty board or boards

I have a panasonic plasma tv. Model #


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!

TH-42PZ80U Panasonic Plasma, red light flashes 10 times


Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.

But need to measure the connection SC2, if it short, it will be the SC board.

The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.

Grainy Sky+ Tv picture


Can't say it's a fix but when you press the tv button to make the picture better, cover the end of the remote and press sky so the tv and box don't pick it up.

It's more of a work around than a fix!

When the red light flashes, it means that something has gone wrong wit h the set internally. The set will have to be taken to a service centre.

Loud Fan


Yes, fans are somewhat the bane of these new TV technologies. With all the mechanical and optical stuf in them now, TV's are a lot less reliable than the good-ole CRT type.
Fans are easy to replace though.

Panasonic TH50PH10 Turn off Automatically


Hi, if your plasma flashes 10 times it means that there is a problem with the sustain driver. This could be an intermittent problem, such as when the set heats up. It should be returned to the dealer as it is under warranty.
