    2 LG plasmas, separate issues. 50PG20 & 50PJ550

    First item up for bids......LG-50PG20.
    Symptom: tv turns on just fine, audio can be heard but screen is completely black. No backlight, no flicker, nuttin

    Best guess: bad logic control board?? Seen these where the Y sust. Went bad but those at the very least had screen glow just no pic.



    Next.......LG-50J550
    Symptom: turns on you hear the relay click then the screen displays screen glow for a quick second flash then the tv shuts itself down right away. I can turn on/off repeatedly and it always shuts down right away. PS board has no signs of bad caps etc.....surface mounted fuses check out just fine. Tempted to just get a new PS board for this one. Am I jumping ahead of myself?

      The LG50PJ models apparently have a kit on ebay. all this tv does is relay click turn itself off, standby etc......

      was this PS board notorious enough to have assembled a kit??

          Audio Issues - Realtek ALC3306 - Lenovo Slim Pro 7 14ARP8 - Type 83AX
          by SoulFreeze
          Hi, trying to troubleshoot some problems with this laptop I just finished repairing which had power issues (Burnt Buck converter - SY8883DFC shorted to ground).

          After repairing the above issue, I realized the following remaining problem,
          Sound only comes from bottom speakers, top palmrest speakers don't work. Neither does the headphone jack (static/buzzing).
          The computer recognizes headphones are connected and displays a popup in windows
          Sometimes, the computer will boot up and the sound will be working fine. However, if I run intensive programs and the computer...

          Lenovo IdeaPad Gaming 3 15ACH - Ideapad 3 well known solder joint issues
          by Nagyesz
          I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.

          All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..

          How can I extend its lifespan? Could reflow help?

          It has ryzen 5 5500h, rtx 2050, no soldered ram.

          Example of the artifacts:

          Asus Rog strix g15 g513ih hn0865 and it's having display issues while running on igpu
          by Skgod
          Hey I am having Asus Rog strix g15 g513ih hn0865 and it's having display issues while running on igpu. Works fine when I open any game or whatsapp windows application. The issues are :
          Black screen, freeze
          The weird thing is that when as long as the laptop is running on igpu the problem keeps happening. But as soon as I open any game or whatsapp windows application, the laptop works completely fine.
          When the screen freeze or black screen I used to move the display lid up and down and it usually works like that.
          So can anyone tell me what would be the possible cause?...

          A2141 (2019 16" MB Pro) Strange macOS install issues. NAND? WIFI? FIRMWARE?
          by duwane
          Hi All.

          Sorry ahead of time for the text wall. This is a strange problem and I have tried to explain it as best I can. I realise this is a hardware forum (mostly), but I am still not sure if this is even a hardware fault! I am hoping that someone more knowledgeable than me in the area of understanding installation logs, or someone that has had a similar issue in the past may have some ideas of what might be causing this.

          The issue:
          Unable to do a clean install of any macOS versions supported for this model, even after fully erasing and formatting the internal SSD,...
