    MSI GT62VR-6RD MS-16L21 - PL10 an PL11 doesn't have voltages.

    hello!

    MSI GT62VR-6RD MS-16L21
    PL10 an PL11 doesn't have voltages. Resitance on these coils 3.5Ohm. It is good rsistance for SR2FQ.
    At U11 VCC and VIN ok
    VR_ENABLE=3V ok
    VR_READY=3V ok
    ALERT#=0V not ok
    SDA only static 1V, no data
    SCL only static 1V, no clock
    Pin19 to Pin20 sense loop ok
    pin32 to pin33 sense loop ok

    And i set U11 in test mode by replacing PR43 to 20kOhm (U11 Pin 40). In this mode U11 generates 1.05V. So in this mode 1.05V i on PL10 and PL11 available. It means +VCC_CORE voltage supply is ok.

    1. is the CPU defective?
    2. what options are available to exclude defective CPU or validate defective CPU without replacing the CPU?
    3. is PMON pin1 necessary for work of the U11? It is low and comes from charger. In Datasheet stays "Buffered total system power. The output current is proportional to the total power from the adapter and battery"

    thank you!

      Powersupply has all the voltages - Monitor still no power
      by Capacitorial
      Hello guys,

      I have a Philips 240B7QPJEB. The monitor seems completely dead.
      I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
      On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
      The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
      The weird thing is, that the Power LED is powered over the TCON board.
      On The TCON...

      Help reading schematic voltages input/output
      by gjgib
      Hello, this might be embarassing since I consider it a dumb question but keeps me kinda stuck sometimes in my journey.

      I want to know if there is any post in this forum which explains my questions. A) When, where and how do I know when X voltage line is input or output. Example:


      I'm battling with this IC to understand it's voltages. It's from non-turning-on Lenovo Ideapad 3 15iil05 - NM-D461.

      I see some lines like +5VL / +5VALW / V9B+ / +3VALW being okay and some others like 1.8VALW / +0.6VS / +2.5V_DDR. I just know that some of them are bad or missing,...

      HISENSE LCD LED TV MODEL HX40N2176F LED DRIVER SN51DP IC PINOUT AND VOLTAGES
      by RossMoodley1967
      Hello

      Need to know the voltages that will be present on SN51DP ic when tv is in standby and when powered on.

      Just to elaborate on the problem with the tv 1.set came in with flash of HISENSE logo on screen then back into standby.2. Now tv when plugged in red standby light present to quickly changes to blue but no backlights.3.Then an hour ago i checked again , came on standby and stayed until i pressed the power button which changed to power on (blue)4.As far as the led driver circuit goes voltage at output in standby was 38v , power on led light up voltages rise 58v-68v...

      Asus Prime x299 Deluxe - no VCCIO VCCSA voltages
      by lol999
      Motherboard after starting show Q code 00.
      No shorts on any rail ( at last I can't finde any)
      All voltage are correct on SIO - 3.3V, PCH power 1V , DDR 1.2V, SPI 8 leg 3.3V
      Nothing get hot, PSU starting, all lights came ON....
      One thing i can see incorrect is no VCCIO and VCCSA voltages and no main power on CPU.
      After deep looking I found dead Synchronous Buck converter CSD97374Q4M that is powering VCCIO for CPU but after replacing it nothing changed. Voltages on it are correct....
      This buck converter is PWM'ed by Asus DigiVRM ASP1405I-62T. Can't finde any datasheet...

      RTX 3090 all voltages normal but not post
      by hallmark1730
      Hello, Aorus 3090 xtreme model card does not post even though all voltages are correct.When I plug it in with another GPU, the motherboard stays on the GPU error light.That's why I can't test it from mats mods or check seems in windows.I checked the pex gate, there is 3.3 volt and 1.8 volt output.

      The only problem I noticed is that the core heats up very quickly. When there is no heatsink, the voltages drop to 0V. But when the heatsink is installed, the voltages are constant.I measured the PCI lanes and there are no broken lines.I am open to all suggestions and recommendations.​...
