I think the charger port flex are identical but I need to make sure before I try to solder one on.

Most likely just a bad screen that needs to be replaced. The smaller cable coming from the screen next to the other one is for 3d touch + home button together. That flex cable tends to go bad with a tear or even a microfracture that can't be seen without a microscope. Bad engineering design by apple for the 90 degree cable bend.

Yes you can, use this guide on how to open it up, no need to physically remove the battery: Lenovo Yoga 720 Battery Replacement There will be 3 screws clamping the heat plate which is attached with the heatsink assembly and an additional two or three screws for each fan. I recommend removing the screws for each fan and unplugging the cables for each fan before attempting to remove the heatsink or fans. Once it's remove clean old thermal paste off the CPU and heatsink and if needed use isopropyl alcohol to clean the rest. Then apply some good thermal paste such as Arctic Silver 5 or equivalent.

You shouldn't need to pay, things like this should be covered under warranty. As long as the glass (screen) isn't cracked it's the display that is faulty.

Either a loose cable, highly unlikely if they put the metal cover back over the screen connectors or the screen has gone faulty, probably their bad luck from refurbishing the screen. I have only experienced one similar problem like this but with a full grey screen and rarely showing normal display when trying to lock and wake it up, this is from getting a replacement screen from a supplier (refurbished ones), bought like 10, one comes up like this. Have to return to back to where it was repaired for warranty :S

So that is a full digitizer assembly which includes the home button that is connected via flex cable soldered to the screen cable. The blank home button which is bizarre because it means it is a home button that does not have that square icon printing on the button, I have not seen any sellers sell a replacement screen without the square icon on the home button for the iPad Mini 1 / 2 digitizers. It is a cosmetic thing But yeah the insulator tape just need to cover the bottom digitizer border of the screen to prevent ghost touching / self pressing home button.

The optical drives are not serialized starting from a certain model of the PS4 non-slims where they moved the blu-ray drive controller circuitry to the logic board, older PS4 models had a little blu-ray drive controller daughter board sitting on the exterior of the blu-ray drive assembly. The problem is most likely the disc-feed motor + blu-ray drive controller board fuse on the logic board has blown. You’ll need to take it to a reputable console repair shop in most cases as this requires micro-soldering to fix.

Yes, that can be done with those. Make sure you transfer the home button from the old screen to the replacement screen as the touch ID on the home button itself is paired with the phone’s mainboard. You can use this guide from iFixit to help with the screen replacement: Remplacement de l'écran de l'iPhone 6 As long as it’s not a iPhone 6s it’ll be compatible.

Try adjusting the volume and see if it shows headphones instead of ringer on the onscreen message. If it says headphones with no headphones installed the charging port assembly that has the headphone jack faulty.

It is possible to externally charge a lithium phone battery with a DC Bench Power Supply by connecting the positive and negative cables (I use multimeter probes) at 4.3V on the negative and positive pins of the battery connector on the battery itself. Be careful not to overcharge I stop charging them when they pull less than 1.0A. To determine polarity it should still at least have some power left to measure with multimeter.

The funny thing is that for some reason the pentalobe bits seem to let the screw nut go out and screw back in.

If you have isopropyl alcohol on hand. You can use it to help weaken the adhesive temporarily when lifting up the adhered home button.

Yep, clean the old adhesive and apply some Tesa 4695 or 61395.

I honestly do not understand why the back cover is removed from the mid frame, you can remove the mid frame silver plastic with the back cover anyway.

They can’t be both PMI8994 Power Management IC’s I’ve looked at them under an microscope and one is PMI8994 and the other is PM8994.

Unfortunately the connector plugs are different and the cables go in different areas.

No. Different connectors.

I would call that a grounding plate as it looks like it provides grounding for the power button assembly to the board. Without ground the power button would not be able to send current pulses when you short the power button by pushing it from the power button itself > power button cable to logic board.

Not sure why they did this because they could of just provided ground on the cable itself. That's my understanding because that put should not of been designed like that.

The thickness / coverage of the area available to put the adhesive is plentiful which allows you to use more adhesive than you need. Anyway what I use is red double sided tape as it's adhesive strength is very good and the thickness is good to use in this case. It's called 'PET red double sided transparent tape'.

I think iFixit sells rolls of them which aren't really expensive at all.
