        Interesting find..see attached.

        The title block references the same part from GMT as posted in post # 2. But the actual suffed part is from Richtek with p.n . RT8231BGQW

        (2-5piece)100% New RT8231BGQW RT8231B 3T=FK 3T= QFN-20 Chipset - AliExpress
        * confirm with the vendor that they will supply the exact part

        Full datasheet:
        Complete DDR Memory Power Supply Controller (richtek.com)


        So it appears that these parts are drop in replacements for each other. Do double check the details of the pinout before sourcing.

            by m1ch43lzm
            Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
            Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

            Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
            by Tynan Dill
            I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

            Upon bringing it home and plugging it up, it showed a standby light.

            I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

            The screen seems to blackout and stay black, but with a flashlight I can see the display.

            With my Playstation 4 connected via HDMI, and running a game I can hear sound.

            Assuming...

            LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
            by Hakuu
            Hi There,

            This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

            After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

            More Details

            TV Model - LG OLED77G1PUA

            Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

            Sony xbr-65x900c main board issues?
            by jb_Bak
            Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

            Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
            Power Board Connector that goes to Main board
            CN6401
            Pin 01 NC
            Pin 02 NC
            Pin 03 "BL_ON": 0V
            Pin 04 "N/C"
            Pin 05 "STBY 3.3V": 3.5V
            Pin 06 "GND": N/C
            Pin 07 "AC_OFF"...

            Panasonic TC-P54VT25 No image. A or D board?
            by canadaboy25
            I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

            The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

            I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
