    Acer SA230 Flickering Issue

    I got this flickering issue as in this video

    https://drive.google.com/file/d/1MHr...hcpjotoN_/view

    The monitor keeps flickering for like 5 seconds and it gets solved after 5 seconds. First I thought it is the power/display board so I purchased one from eBay but the issue persisted.

    Checking the board where cables are connected I found out the SM4047 IC is getting hot.

    The image of the board is attached. Is there anything else I should check before I order the IC?

      Checking further I found out all of these marked components are shorted to the ground. shall I start removing the components before removing the IC?

      Thank you

          Acer Helios 500 (PH517-51) - unexpected reboots when laptop is warm (cold solder joint issue?)
          by Mirenia
          Hi everyone,

          got an Acer Helios 500 Laptop (PH517-51) for diagnosing with a strange issue:

          The laptop runs for a while (1-2 hours, sometimes less) and then suddenly shuts completely off, like someone pulled the power cord and restarts immediately after on its own.
          If this happened once, then the laptop only runs for a few minutes until restart.
          This happens regardless while staying in windows or uefi or in a linux environment.

          At first I thought of a normal overheating issue, but as I monitored temps with HWInfo64, nothing seems very hot.

          ACER BM320 Monitor - Horizonal Flickering Lines After a While
          by reessi
          Hello,

          The monitor started off showing flickering thin (1 pixel) lines horizontally every say 3mm..

          They are black on the right and gradually fade to nothing on the far left.
          They start either after 5 mins or up to 2 hours after so annoying for testing.
          They flicker continuously very fast! With a slight pause milli-second every second.

          Initially I cleaned the LVDS cable and connected to the T-Con and then it worked fine for 3 weeks but not sure if this was just co-incidence.

          I tested each half by removing the first the left flex from...
