    HP TPN-Q195 7265NGW main G3BA N17P not start

    Hi everybody,
    I come across with this main.
    It starts and switch off with the button.
    It has all voltages risen. PLT_RST is UP.
    However, the LPC bus is risen but hasn't any exchange there (Hasn't any POS code).
    I removed CODEC, but it doesn't help.
    I haven't boardview and scheme for this board, only for G37.
    I have not any ideas. Probably HUB issue?
    Would you help me please.
    Thank you.

      CLK_PCI_LPC present?

      can you post pics of your measurements of LPCFRAME/LPCAD0/LPCAD1/LPCAD2/CLK_PCI_LPC?

          CLK_PCI_LPC - pulsations is missing
          But all these signals have 3.3v pull up.

              Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
              by cheeky2
              I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
              Obviously the same LVDS connector for the screen connection...

              Hi and thanks in advance for any input you might provide!
              I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
              Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

              Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

              HP OMEN g3ba n17p NO POWER
              by madjid911
              Hello, this laptop omen 17-A037NF (motherboard DAG3BAMBAH0 REV : H, SN 5CD812BWNM) of mine won't start at all. The charging light is flashing. The battery is charging properly, the 20V is being supplied, the SIO chip is being supplied with 3V3 and 1V76. I have 5V on one coil, but I don't have 3V3 on the other coil. Therefore, the EEPROM chip isn't being powered. I replaced the 3V3 chip (SY8286C awv7YD) with the SY8288B and the JW5068C, but the result is the same.

              So I took a closer look at the 3V3 chip. On pin 11 EN, I measured 4V53, Lx pin 6 0V, BYP 3V3, FB 0V, BS 2V9, and VCC 3V3....

              LG 55NANO77SRA TV ā€“ Menu scrolling by itself even after removing button board (Main Board EBU66792103)
              by ygorsan
              Hi everyone,




              Iā€™m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







              šŸ§© Problem Summary:
              • The TV keeps scrolling through the menu or selecting items by itself.
              • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
              • The remote control is not in use (batteries removed), and the TV still shows the same behavior.
              • I

              Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
              by Asraf Atb
              Hi everyone,

              Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

              Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

              I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....
