    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.

      Thanks...model no. of TV is TH-58PE75U.
      Board A in question part no. is TNPH0692(1)A

      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...

      I have also uploaded page from Factory service manual showing A6 and A7 connect and concerned voltage..

      Please advice...

        Lenovo Yoga 13 Panasonic, no video, fan OK, missing voltage rail (?)
        by jaroslav.psenicka
        Hi all,

        I have a Lenovo Yoga 13 Panasonic here, when powered
        • both fans spins (the sconds starts with a bit of a delay), no image neither on HDMI nor the display
        • most voltage rails seem OK (see image below, red labels)
        • resistnace to ground mostly seem OK as well (blue labels)
        the only suspicious is the 0.0V rail (2nd from left, top row)
        • the resistance to ground is rather low (1.9ohm)
        • when injecting the voltage (1V), it consumes around 200mA, seems OK to me (?)
        also tried new BIOS, no change
        I can't find a schematics for the board - can some of you gurus look at the voltages?...

        Panasonic TC-P60S30 - no standby voltage
        by BobbyMJ
        Hi All,
        Wanting to learn some electronics repair skills.
        I found a non working Panasonic TC-P60S30 and this is my first project / attempt.

        So far I have found a blown cap on the main power supply board.
        After replacing it there's still no standby power.

        Poked around and found a resistor on the PSUB power supply board that measures open.

        An online resistor calculator shows this is a 93k ohm resister.

        My questions:

        Is that correct, 93k ohms?
        Is it a fusible resistor?
        Lastly, how do I know what wattage?...

        Recapping Sony ICF-SW55 - verifying cap values
        by proxneo
        Dear reader

        I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.

        At the moment, I have selected replacements based on the following list of values:

        3 x 470uF 10VDC
        3 x 4.7uF 35VDC
        4 x 47uF 50VDC
        8 x 22uF 6.3 VDC
        1 x 220uF 6.3VDC
        5 x 100uF 6.3VDC

        Which...

        Trip light 2400 watt line conditioner bought used issue with low voltage oscillation going on between relays
        by sam_sam_sam
        I found two capacitors on the board and one of the leads on one capacitor had bad soldering joint and the other joint connections not much better and there were several soldering joints that way to much flux around the joint redid several of them

        The capacitors were a non brand that I did not recognize they got replaced and now it does not oscillating between relay but what concerns me a little bit is when the voltage is a little bit low the output voltage is around 130 volts and then drops down to 115 volts this happens around 105 to 108 volts if remember correctly

        Now...

        3+1 Voltage Regulator for IMVP-7/VR12 CPUs

        Compliant with IMVP-7/VR12, the ISL95831 provides a complete solution for microprocessor and graphic processor
        core power supply. It provides two Voltage Regulators (VRs) with three integrated gate drivers. The first VR can be
        configured as 3-, 2- or 1-phase VR while the second output is 1- phase VR, providing maximum flexibility. The two VRs share the
        serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two chip approach.
