    Component ID/value

    The part J6301 (the power board) shows in Board Viewer but there are no values for any components attached to the board. There was black scorches around the SMD, I tried to resolder it but the whole side was burned off.

    Whats a value that should work?

    ASUS ROG
    60NB0180-MB4020(211)
    G750JHA

    Found board viewer schematic @

    Thanks

      Re: Component ID/value

      Assuming you've resolved whatever issue caused it to burn up in the first place (I hope)...

      That is just the current-limiting resistor for the LED. It's being powered by 5V. You can use Ohm's Law to figure out an acceptable current.

      5V / current = resistance

      5 mA = 1k ohm
      10 mA = 500 ohm
      Etc..

      Somewhere in that range should be fine for most LEDs. I wouldn't go to a higher current (lower resistance) unless it is obviously too dim.

                  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...

                  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...

                  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"...
