    34UM68-P , LG monitor schematic / part ID help please

    Hi all

    This monitor not powering with white front LED on .

    Discovered buck converter IC403 to be faulty . It's marked IAEDH .

    PIN 6 ( GND ) measuring S/C with PIN 5 ( 1V8 O/P )

    The 1V8 supplies the CPU , which hopefully hasn't been damaged .

    Package type i believe is SOT23-6 , but could do with some help to ID device .

              Acer x163w Monitor PSU schematic
              by atunguyd
              Ii wonder if anyone can help me. I have a Acer x163w monitor which is not powering up. The PSU main capacitor's one leg had completly come off - I replaced it but the PSU is still not outputting DC. I found the monitor in questions service manual here on manuals lib but the schematic in there is a completely different - the schematic shows no mosfet to drive the transformer while the one I have does use a mosfet - also the schematic shows only one optocoupler but mine has two.
              The PSU board is labelled FM-20A02-AAA made by APD as per the image below. I am trying to find a schematic for this...

              AOC AG493UCX 49-inch monitor - Firmware request
              by wattage
              Hello Badcaps Community,

              I purchased a preowned AOC monitor that is not working and out of warranty. It was sold as not working. I am looking for guidance on self-repair. In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.

              The problem is that it will not display a picture on any of its inputs. And the on-screen menu does not appear. The power button works properly. It powers on with the remote as well. But the on-screen menu does not appear, even when not connected to any...

              Hi There!
              I'm trying to help my friend who owns a restaurant be just bought.
              He has a very long LED strip running along all the walls and columns. The strip is attached facing down 2in above the floor, using a wall panel that ends in a metal rail that finishes the panel underneath
              It's stuck using, I guess, the 2 sided tape that comes with the strip
              The issue is that like 1/2 of the full length, including 1/2 one wall, another entire wall, and one column, flickers after 4 or 5 minutes ON. Particularly it flashes staying OFF most of the time and flashing ON for 1 tenth...
