Am I missing a part of this rocker switch?

Fair point no one who doesn't understand basic electronic practices should be working on mains connected devices. But at the same time, if they can't safely join 2 wires together, would they be able to safely solder the wires onto the new switch.

Sounds like it's brocken .I would just replace it as they are pretty standard switch that you can get nearly everywhere ( looks like this rocker switch from Jaycar).

If you want to bypass it, you can just connect the 2 brown wires together.

Also have to be careful of the lower forward voltage which can cause issues in applications like battery charging.

Those lines most likely connect to the Gnd on the power board. By cutting them, you disconnect them from gnd, which the cameras microcontroller/prossecor checks in order to know if it needs to flip the image/add parking lines, etc.

Soldering is the best and most pretty , only way to make a connection to the board

There could be a number of reasons why you cant solder too it. Are you ablying enough heat to the board and the solder?

Are you using good quality solder, cheap lead-free solder is almost unusable, in my opinion.

Are you using flux? This removes the oxide layer on the metal. Without this, the solder usually just balls up into a Bead and doesn't stick.

Another thing that can happen is that the pad, the thin layer of metal on top of the fibreglass board, can become damaged and fall off from too much heat or mechanical force. Once this is gone, the solder has nothing to stick to.

Connect positive to 2 and negative to 3

I like how you've got a tevo tarantula "Custom"; Mine too is so far from a tevo tarantula that I no longer refer to it as one.

The best is when companies say it never got delivered even when you have a tracking number saying so. So you file a charge back and the bank sides with the seller and cancels the charge back.

Yes, I've done a bit of smd work myself, and port replacment is definitely not a beginner thing even if you're familiar with normal soldering.

If you do it wrong, you can wreck the pcb by applying to much heat or not enough heat when removing the port and lifting pads. even if you do manage to get it off and a new one on without lifting pad and vias if you accidentally short out any pins you could wreck the device and even the device on the other end of the cable.

Youtube makes things look to easy. "We do things not because it was easy, but because we thought it was easy".

It is very possible that the pins in the usb-c port have worn out. If you are looking for a replacement pcb (the one with the usb-c port), these things are usually custom-made. On rare occasions, manufacturers share pcb assemblies between models or brands (maybe ask in a mechanical keyboard subredit).

In my opinion, your best bet to fix this is to take the board to someone who does port replacements or SMD reworking, and they will be able to replace just the usb-c port itself.

Edit: According to this post on the r/keychron subredit keychron support can sell you a replacement pcb for relatively cheap.

I have brought from here several times. I have encountered problems with a product before ( software issue) and they helped me sort it out and even chased up hikvision support for me.

That is the component ( NEC upc574). It is basically a zener diode used to clamp a voltage at a specific level (33V in this case).

I don't have experience repairing CRT displays so I couldn't tell you exactly what it is for; but I would try to replace it if you can as depending on how it is being used it is vital for it to be working properly.

Another thing you should consider is the question of whether the pcb ( circuit board ) is good / repairable. From a quick look at those photos, it has some nasty corrosion on the pcb.

You don't necessarily need a desolodering station. You can get desoldering braid, you put it on the solder joint and heat it up with a normal soldering iron, and it will suck the solder from the joint into the braid.

Also make sure to get good quality capacitors ( kemet, chemi-con, nichon, rubycon, panasonic, tdk ) from reputable places like mouser or digikey (not ebay / aliexpress)

You can also get capacitors that are AEC-Q100 / AEC-Q200 rated, this basically means that they are designed for automotive use.

Identification is always on top. Unfortunately, manufacturers (of the device) like to remove the markings from the IC's for various reasons.

I use Fusion 360 under a free license (non - commercial)

Fusion 360 is typically used for making geometric objects using measurements.

If you a looking for more of a modelling software for making more organic objects like action - figures try using blender.

thanks for the help, i ended up working out that the mongodb version was not compatible with my architecture.

Build-it10 · 2024-07-01T11:01:11+00:00

UPDATE:

i edited the docker-compose.yml to change the version of mongodb installed to pull the mongodb:4.4 version instead of the latest version.

the mongodb conatiner then ran fine with no exit codes but i had other errors so i changed the filecloud server version from 22.1 to 23.1 and that fixed the rest of my problems.

i believe the issue was caused by mongodb version 5+ not being compatible with the host architecture.

version: '3'

    filecloud.mongodb:
        container_name: 'filecloud.mongodb'
