Hi,

Other than suggesting a full hard reset (unplug from the mains for a couple of hours or overnight), I wouldn't suggest doing anything with it otherwise the warranty may be void.

If your concern has not been corrected after completion of the above procedure, perhaps your best bet would be to seek the services of their authorized service personnel.

Hope this be of initial help/idea. Pls post back how things turned up, if you would waive the warranty and try a DIY or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again hegemony,

    With the indulgence of IB4G2008....

    Search on the net disclosed that 8 blinks indicates fault in Driver SOS 3 SS Board (SS energy recovery circuit).

    Other errors are:
    1 blink STV 5v sense DG Board
    2 blinks 15v SOS D Board
    3 blinks 3.3v SOS D Board
    4 blinks Power SOS P Board
    5 blinks 5v SOS D Board
    6 blinks Driver SOS 1 SU / SD / SC Boards (SC energy recovery circuit)
    7 blinks Driver SOS 2 SU / SD / SS Boards (SC floating voltage area)
    9 blinks Panel Config. SOS
    10 blinks Sub 5v SOS / Main 3v SOS DG Board DTV 9v SOS / Tuner Power SOS
    11 blinks Fan SOS PB Board
    12 blinks Sound SOS H Board
    13 blinks Communication error DG Board with IC8001 (Pesks Lite 2)

    Though I must say that common problems with your model would be clicking sound and/or delay in video display (which according to some service personnel are normal). Your particular problem indicates a hardware fault and for all intents and purposes better be left to authorized service professionals.

    Should you venture a DIY, please be reminded of safety precautions when dealing with electrical powered devices. It would also require that you be familiar with electronic components and circuitry, use of a DVM, a soldering iron and access to a service manual or at the very least a schematic diagram with voltage readings.

    Cheers.

I have a Panasonic Viera plasma and everytime i turn it on it lasts for about 10secs then turns off. The red light blinks 8 times. The model number is th42px7a. Should i fix it or buy a new one?


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, power supply board is dead, u 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.

I hope this will help in solving the problem......

Panasonic 42 inch Viera Pixel Distortion


We have the TH-42PX70A which has the same problem. It comes and goes..It is only 2yrs old, warranty has run out. The moving red pixels are on the black and the cyan pixels are on the white. It will go away for months and then return for a few days. It is not an antenna problem as the signal is still there.I am taking it in today for the tech to look at, but I turned it on this morning and it is fine. So I wont be able to show him.. (took pics though).Everyone says they are the "best" and all that, but every now and then you get a lemon. If it turns out to be too costly, I will buy a new one and it wont be a Panasonic.
