How many blinks is the LED showing? The number of blinks correspond to a service code so that technicians can better diagnose the faulty component inside.
I'm doing factual research for a potential class action lawsuit regarding these "blinking lights of death" problems that the Panasonic plasmas are showing. I'd like to hear more about your experience. It's been a while since you've posted here. Have you contacted Panasonic? If you're willing to share your story with me, please email me at [email protected].

My best guess would be that your SD board is bad. On this model think the part number is TXNSD1EDUU.

We recommend you test the TV with multiple devices on multiple sources.

7 blinks? Driver SOS 2 SU / SD / SS Boards (SC floating voltage area). These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy. For more information, check the link http://electronicshelponline.blogspot.com/. If the blinks continues, and non-stop, the fault should be with its main system control IC, and with the memory IC.

Try disconnecting all HDMI cables and plugging the TV into a new wall outlet. If the issue is resolved, it may have been caused by a small power surge from either your wall outlet or one of your source devices.

You don't need a driver. Just connect it to your PC and choose in the TV menu correct input source.

thats a sos error for numerous supply voltages missing. Send a email to me for assistance as I cant post the info here [email protected]

yes you can

how many times does the power light blink? Let me know and I will assist with the issue.

There are two guides, one for 10 blinks at power on:


or, 10 blinks at plug in:

Good day!!!That problem is usually cause of faulty capacitors on the power supply board..Just follow this instruction to fix your TV..1. Open the back cover of your TV.2. Look at the power supply board..Its normally connected to the power cord..3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..5. Some of the capacitors not bulged so its better if have a capacitance meter

Hello,

You need to check the output voltages of the power supply to see which one goes off. It may be due to short circuits some where,if otherwise the power supply board is dead, do you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Hoping this will here in solving the problem.....

It could just be a bad connection on the driver board or worst case it could have failed.

First you need to disconnect from the mains and leave for 5 or 10 minutes to discharge.

If you remove the rear of the screen you'll see the driver boards as items 7 & 8 at the folowing link.

Disconnect the ribbon cable from the board thats below your black line and put some tape around the end of it to make it safe.

Now turn the power back on to check that it's the correct board in relation to your black line.

If it is then turn the power back off and leave for 5 to 10 minutes again.

Now check that the ribbon cable and control board show no signs of corrosion or damage.

If they both look OK then reconnect the ribbon cable making sure its fitted correctly.

If when you turn on again you've still got the black line then you've 2 options.

1) Remove the board and check for dry joints and resolder where necessary.
2) Replace the board.

Let me know how you get on and I'll look for replacement board costs and availability.

Hi.

This sounds like your tv has been the unfortunate victim of electronic "flu".

Alot of flat screen tv's are suffering this same problem.
This has nothing to do with anything that you have done to the tv, ok?
This is because the electronic parts manufacturers back in the mid-90's decided to take profits over quality.
See, they made about 5,000,000 capacitors that were all defective, but instead of trashing them out and making good ones, they decided instead to leave them on the open market, and now they have finally made it through the manufacturing process and have been installed in tv's, computer monitors, car stereos, alarm clocks, and video game systems.
All these defective parts are failing now, instead of lasting the 25-30 years that they were supposed to, some are lasting only a few weeks to a few months.

The worst part of it is, since the parts that are defective were made so many years ago, the current companies that have been installing them aren't liable for the parts failing.

The vast majority of the time, no warranty work is allowed.

The TV can be repaired, but only as an out of pocket expense.

If you decide to get the set repaired, get estimates of the repair costs first.
I say this because to get the bad parts replaced with good ones can be al,ost as expensive if not more, than buying a new set.
There are a couple of places that have specialists trained to do the repair, if you decide to get it fixed.
Fry's, BestBuy, Staples, CompUSA, and Radio Shack all have trained specialists for this repair, because capacitors can hold SERIOUS electric charges in them, and if you thied to do the repair yourself, you could quite easily get injured.
I hope this helps you out, and try to have a good day.

I sugest u take this tv set to an expert, this is a comon power suply problem with these appliances and can be easily fixed by replacing 1 or 2 items. Go for it, its cheap.
