    Mbp 16" 820-01700-a

    Working om a Macbook Pro 16" 820-01700-A board. The problem was left and right wing bottom was damaged by Cockroach. I replaced all the components that was corroded. After replaced board was turned On everything working. I put it into my ultrasonic cleaner dry the board and assembly the board was turn on anymore. PPBus was 12.69V schematics 13.1V. DC-IN only have varies from .10A to 0.04A without connecting the battery. Is the ISL9240 is bad?

    Update:
    T2 Chip is getting warm under infrared Camera
    SCM_RSMRST_L = 0v

                  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...

                  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...

                  TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                  by howardc64
                  All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                  • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                  • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                  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"...
