AOC AG493UCX 49-inch monitor - Firmware request

[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...

I look to find some simple solution to execute Fn+left arrow once at winxp startup... It might be some simple specific command aplication, or batch script, or some C code (I have C compiler, but thats it)... can anyone help with idea or solution? On internet can find some sofisticated programs that can do such things and much more, but I not interested to load it to system for that.... ... ... If you interested in what is purpose... I have some bug or so on my laptop, and on every shutdown reset backlight to maximum, just flash one moment before go off... on next boot backlights is stuck to...

Hi folks.
I have a 640 which doesn’t charge using the barrel connector, only via USB. Internal voltage rails only go up to 12V, they rise to 19.5 with the USB C.
Can Anyone who has the schematic lend a hand? I can read them fine so just a link would be great, but also any insight if you’ve seen this before.

Also, is there a list connecting the HP series model
numbers to the COMPAL model numbers?
thanks

I replaced the broken usbc connector on this Ciontek CS50 mobile device. It worked fine afterwards, although it looks like the battery went down quickly and the device got warm at the back (battery section). After putting it in standby for a while it didn't came back anymore?
The battery is still charging (red led), but no power on.
I had another look at the usbc connector, it looks like one of the components is melted down (blue marking)? I have a picture of an untouched device and then the repaired device with 2 pictures; what are these components with B1 and PB marking? Are these...

Hello
I'm looking for the circuit diagram for the MEDION AKOYA S5612.

Hi people!!
The owner said it showed bad picture once in a while (attached)
I see that there is back light but no picture.
I want to ask if it is possible to disable the NVIDIA GPU and use the intel one?

Also attached schematic and BDV

Hi guys,
I have a MacBook Pro M4 16" A3403 on the table with water damage. I allready found the problem within a bad cap. As far as my researh went, I couldn't find the schematics and boardview for this MacBook model. They seem not to be released now. So my question is if anybody has a working A3403 on the table and could tell me, which specification this capasator has?
I attached a photo of the missing cap. It's on the bottom side of the logicbard.

I am very thankful for your replys.
Thanks in advanced and best regards from Hamburg Germany...

Hi,

I'm looking for assistance with a Mac mini (M4, 2024), model A3238 (Model MCYT4LL/A), which I recently purchased. The front USB-C ports are not providing power.

Upon inspection, I've identified that a chip and an adjacent capacitor have been physically ripped off the logic board near the SSD connector.

Could anyone provide information on the specifications of this missing chip? Additionally, I would greatly appreciate it if anyone has access to the schematics and board view for the Mac mini A3238 logic board.

Thanks for your help!
