Take a look at 7:45. You accidently wicked away to much solder from one pad. For me the pad looks like one that is used to disconnect some part of the circuit for debug purpose. It´s the pad above the 4 tht holes from the connector you removed. And another thing, Playdoo is conductive. If the green stuff really was something like this and it shorted both legs of the component, it may be broken.

@ysdoho Год назад

+1 the component above the pad looks like a voltage regulator and the solder was there connecting the traces that go to a via. You can see the changes when you compare from 1:08 to 7:45 or 8:39

@dkgadgetfan Год назад

Yes, you are right. That is the problem. The 5 pin IC located right next to the "solder pad/shorting pad" ("S4501" in the schematic) is a power switch for the 3V LCD voltage. If the pad is not shorted, then the APU cannot enable the switch, and the LCD will be permanently off.

@RealNovgorod Год назад

Good catch! It's the solder bridge below the 52445 IC. Imagine if that's what's powering the mux chip...

15:15 to avoid the messy flux syringe, i pull the plunger back a bit before laying it down, every time. This prevents it from wasting flux every time you set it down Hope this helps

@SteveRand Год назад

Same, there is residual pressure from the rubber seal that keeps forcing a bit more out. Back it off a fraction and it doesn't leak!

Received my order of low melt solder a couple of days ago and finally got to use it today. Got my first customer iPad charging port in the shop and I’ve practiced for hours removing ports from donor boards and I was never able to get the port to just slide off the board with the “low melt” that I had but with yours it came right off and I wasn’t even trying to make that happen!

Hey Alex, Long time viewer first time commenting.. I have a small cup I put my syringe in, nozzle pointing up, and if I am not using it for a while i pull back on the plunger a little bit.. Also at 22:22 it looks like a cracked component to the right and below the printed "6505" I enjoy your videos, keep up the good work..

@RogerTannous Год назад

Hey Alex, cheers from Lebanon ☺ I put the syringe on a piece of aluminum paper so that I can easily grab any flux that falls from it. Someone said in the comments about a key combination, Fn + screen function key, and it seems it's the fastest test you can do as long as the laptop is still assembled. Otherwise, if no usual component seems to be damaged, I guess it could be a hall effect sensor on the board, it's used to let the computer know when the lid is closed. So if the hall effect sensor is faulty, the computer will not power the screen on to save power.

@ConcertLD Год назад

When i am done with the flux, i always draw back on the plunger this helps preventing making a mess everywhere. It only takes a few mili seconds to do it. Once you develop muscle memory you dont even think about. My boss I used to work for in a TV shop back in 1997 taught me that.

@MichaelGiacomelli Год назад

If you have compressed air, one of those 60 dollar AliExpress glue dispensers is amazing for flux and paste. At 60 psi you can dispense amtech through a 24 or 26 gauge needle effortlessly, but the hole is so small it freezes the instant you let go of the button. Makes applying flux much easier as well since you can feed it directly where you want it.

@Mr.Bearded.Mechanic Год назад

Mesmerizing to watch that wick sucking up the solder🤩. For the flux syringe, maybe something that you can clip it in, or place in a grove in that way it will sit on the syringe wall.

Apply a bit of pressure on the motherboard when testing and see if the image comes back.(in case there is a bad connection in the layers of the board or a bad solder ball under a PGA chip.

@bloeckmoep Год назад

Could be that one of the interconnects in the layers is bad/marginal and heat did make the gap between layers further go apart, as the glass fiber reinforced epoxy has a tendency to bend when hot. Oh how i hate multilayer boards.

Keep your flux syringe tidy by gluing a small sponge that is dense to your desk somewhere and stick the syringe in it to keep it handy and clean. Change the sponge out when it is too messy. There are very dense little white kitchen sponges that are good for it.

RE flux leaking from syringe, i put together a stand to hold syringe with a piece of insulated Cat5 fixed at rear of stand. I place syringe in holder and simultaneously push syringe into Cat5 so Cat5 goes up tip about 15mm. The Cat5 seals tip nicely; never a drip or glob at the end.

Just apply a bit of negative pressure on the plunger of the flux syringe while keeping it down on the bench, otherwise the flux seeps out because of the residual pressure in the syringe.

Static discharge? For a while I worked at a company that had a lot of mysterious board failures. They also had no static control protocols. One one run of boards, they had a 60 percent DOA rate. Coincidence? I don’t see a lot of conductive mats and wrist straps near you. A while back I was patting myself on the back at having fixed a Tektronix fancy and fast oscilloscope. It was worth more than my car. One careless move with a screwdriver, there was a small static spark, the scope started displaying funny lines and two minutes later the main irreplaceable Tek IC died. I got a lot better at wearing a wrist strap after that ignoble episode.

Possibly a corrupted graphics driver or a problem with the LCD display back light? Since an image can be gained using an auxiliary screen, these seem to be the obvious potential problems. Then, Try to wake your computer by jiggling the mouse, pressing a key on the keyboard, or quickly pressing the Power button. If your computer is awake, but the monitor is still asleep, you can force it to wake up using the keyboard shortcut Win+P or Ctrl+Alt+Del
