    XPS 9360 Motherboard Backlight Damaged

    Working on a Dell XPS 9360 motherboard, DPN T9VPC. Cust tried installing new mobo and presumably connected the battery before connecting the screen. Now system boots with image but no backlight. External monitor is fine. LCD panel itself was tested OK on another XPS motherboard.

    Does anyone have a board view for this model? Or suggestions on backlight circuit repair?



    Thanks.

      UN65TU700DF picture and sound but no backlight. BL tests ok but repl. PSU didnt fix!
      by triplefour
      this tv is throwing me for a loop. do samsung tvs no longer have the backlight self test feature built into the power supply?
      i tested the backlight with my LED tester and it lights up both strips. one of them reads 100v and the other reads 63.7v.
      unplugged mainboard from power supply but left backlight plugged in, and then plugged psu wall power in. expected to see backlights light up but see nothing.
      according to how ive diagnosed in the past, this would almost always be a bad power supply. replacement power supply was cheap like 20$ from ebay. but still i get not even...

      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
      by acedogblast
      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

      Asus ROG Strix Scar G533qm with a G733qm Motherboard, can I modify the Bios to accept G533 Bios
      by glovecaps
      Hello,

      I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.

      My question is, can I update the Bios on this G733 motherboard to a G533 Bios.

      The reason for wanting to do this is that the keyboard isn't working as it should, and I think this...

      Motherboard LA-B972P it has no backlight
      by resistor83
      hi everyone, I have this hp laptop, motherboard LA-B972P that hasn't had the backlight from a few days. However, you can see the image through the flashlight but without backlight.
      I also tried to change the monitor but the backlight is not present. It can only be seen through a flashlight. So I guess there is a problem on the motherboard.
      What measurements could I start taking?

      Thank you...

      Guide me through repairing a Dell p2210f LCD ccfl backlight monitor
      by DanPoka
      I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
      Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
      This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered...
