Turboswordsman

Good day everyone! Hope you are all doing well. I have a mooka projector for a theater set up and one of my friends did something to it and now it’s stuck on this screen. I haven’t had this happen before and I don’t have access to the actual controller, so I browser around on google and found nothing! Not even a manual. Does anyone know how I can get rid of this screen? Thank you so much for your time!

Well you can't take out the ram and expect it to boot so put the ram back in. CPU failure is pretty rare, if anything broke it would be the motherboard. You could also search the internet on how to short the power switch pins on the motherboard. That rules out if the button on the case is working or not.

1600 does not have integrated graphics...you need to connect the gpu for a video output...and no cpu can run without rams...

Normally you have a motherboard and a stick of RAM. You just place the stick of RAM in the slot for RAM on the motherboard and you're done, you upgraded your memory.
With 'soldered in memory', the motherboard and RAM are integrated into the same circuit, so instead of having the RAM be a separate stick, it's soldered onto the motherboard which makes it much harder to upgrade/replace. This is where the hate for that sort of practice comes from.
 
Technically you could desolder it and solder in new memory, but it's possible the manufacturer has made it so the machine sees other memory, plus the way this stuff is made could be quite complex.
What I have shown below in the spoiler here is a basic stick of SODIMM (laptop) memory. The black rectangles on this green stick of memory is the actualy memory, the gold pins on the bottom are the interface used to connect to the laptop and everything else makes this function together.
In theory you could desolder these BGA chips (will explain more on that later) and desolder other memory chips on, but this 'kit' of parts may not be able to recognize more memory. If this was a 8GB stick of memory, these black rectangles would be 1GB a piece and you could try soldering on 2GB memory chips, but it may not recognize it.
 
Now these are usually also BGA chips, which if you don't know anything about soldering; I'll just say they are quite difficult to solder on correctly.
For more information and some experience with BGA chips, I recommend watching Strange Parts' video on upgrading an iPhone storage. Here he shows the process of soldering memory onto a phone board.
How this works, is the board has some amount of connection points and the memory has solder 'balls' on the bottom of the chip. You have to heat up all the balls properly to make them adhere to the board. Else you won't have a stable connection. Apparently in factories they use XRay machines to make sure all balls have adhered properly.
 
These image will give a simple illustration of how BGA works:
 
 
In short:
Memory is physically soldering to a board, instead of easily removable. This makes replacing/upgrading it extremely difficult.

if you have a device with soldered ram just forget about upgrading it, the equipment you need costs more than any of the devices you may want to upgrade.

That it's literally soldered to the motherboard, i.e. there are no DIMM slots to put in more or different sticks. I'm not sure if you can desolder and replace/upgrade them, but I don't think you can. Definitely not without special equipment though.
 
This is common practise in MacBooks (AFAIK) and ultrabooks, which is why it's typically recommended with laptops to buy the model with maximum amount of RAM you think you'll ever need on it (and can afford of course) in any use case you can imagine.

There are not really any commercial solutions to upgrade the CPU cooler in a laptop. They're usually proprietary. Most you can do is upgrade the thermal paste and maybe place the laptop on a desk cooling pad with fans to help temperatures out a bit.

no, unless you don't mind the laptop being stuck to a desk.
 
if the clock speeds go up thanks to extra cooling and the amount of work per unit time stays the same, then yes

Do you want it to still be a laptop? If so, the only thing you can do is replace the thermal paste. This won't improve performance at all if you're already running full turbo speed. If you want to do a fun DIY laptop into desktop project then you can slap a huge cooler on that baby and overclock.
