    Lg 42 issue

    Hi forum,I have not stated model but will re edit at later stage,yet another faulty TV set,on switching the television set on,it displayed a pure white screen,then I heard a crackle,I then briefly switched it off incase it blew my electric box,
    Left it a hour opened it up and noticed a couple of blackened out parts along with underneath the psu some kind of iffy soldering or is this normal for Lg,can I ask what would have caused this ? Was in dry storage

          Firstly I would check the gamma voltages across the tcon board
          but it may also be bad tab bonding issues

              Checked mains fuse and other major parts for shorts using a DMM ?

                      MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
                      by rounin
                      Hi everyone,

                      I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

                      🛠 Original Issue
                      The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
                      Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

                      I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

                      ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

                      Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                      by ugamazing
                      I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                      We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                      Hello guys!
                      I have a strange issue with my laptop keyboard and I'm lost trying to detect what's wrong - the KB9028Q-C or the keyboard itself.
                      It powers on OK and has no other issues except the following:
                      • CAPS LOCK does not work at all
                      • Fn button toggles Flight Mode
                      • When I press 't' or '5', it produces 't5', and when I press 'y' or '6', it produces 'y6'
                      • (with SHIFT pressed: 't%' and 'y^' respectively)
                      I initially thought it was a keyboard malfunction (internal short, etc.),
                      but when I press and hold...

                      Alienware 15 R2 Service Tag: DL7NN32 ISSUE (Battery is not charging)
                      by Simone Vergani
                      Hello everyone,

                      I'm experiencing an issue with my Alienware 15 R2 (Service Tag: DL7NN32). The laptop works perfectly when connected to the AC adapter — it powers on and functions normally. However, the battery does not charge. If I disconnect the DC adapter, the laptop shuts down immediately, as the battery is at 0%. I have replaced the battery with a new compatible one, but the issue persists. I also replaced the AC adapter with a compatible one, but the battery still doesn't charge.

                      To assist with troubleshooting, I'm attaching two power circuit schematics:
                      • Power
