    Are these voltage values look ok on Panasonic TV?

    TV model no. is TH-58PE75U ..it has no picture...few minutes after powering it on, the led starts blinking and it blinks for about 13 times ....I found Factory service manual and it says

    Communication error with IC8001(Pesks lite 2)
    and check board A and board part no. is TNPH0692ADS Or TNPH0692(1)A

    So I checked voltage on two connectors from power supply to this A board just to verify if power supply is ok or not..

    And here are the voltage I found..
    Voltage on first connector

    1st pin-15.73 V ,
    2nd pin - 15.73 V ,
    3rd and 4th zero V,
    5th- 5V,
    6th,7th and 8th - 0v,
    9 th- 3.73V and
    10th and 11th it is 0V

    Voltage on second connector and 12 pins..

    1st,2nd pin-15.73 V
    rest of other total 10 pins - Voltage is zero.

    Total pins on this connector is 12 pins.

    Can you please confirm if above voltages look ok?
    Thanks in advance,
    Vik

    Is there a label on or near the connector? It should tell you what voltage to expect. A nice clear picture of the label and the whole back of the set would help.

      No there is no label on or near connector...
      There is a label in metal box where this A board fits in ..and that no. is txfnz01lmtu as attached in picture.....also attached few more pics showing actual board those two connectors I am talking about ...they are A6 which has 12 pins and A7 which has 11 pins...also power supply board picture...
