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]

+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]

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]

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

[@Nocturnal_Owl]

Good eye! Yes, I also think it's because of this.

[@nicolasbrenta357]

Good catch, you can see that there was a solder connection before he wicked.

[@SuperMarioDiagnostics]

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]

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!

[@electronicverse9221]

I also use the same trick

[@RectifiedMetals]

I tried that but there still is pressure in there and a little Ooze still happens

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!

[@RogerTannous]

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.

Alex - I like the extra time you spent explaining your solder/de-solder process. You answered a lot of my questions in this one video. FYI I take the plunger out of the flux syringe and stand it upright. A little bit comes out but not that much and its not enough to leak all over.

[@marty6668]

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..

[@MichaelGiacomelli]

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.

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]

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.

As soon as your done putting flux on. Pull the syringe plunger back out a tiny bit and it will stop the flux from leaking out into your cup or holder. It works for me.

[@marktolner2922]

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.

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.

Flux syringe holder. I use one of those old spring style iron holders. I reversed the stand so the tip of the syringe points to the sponge tray. I can use a blade to scoop the blob to smear a spot when needed.

[@lasseystad3266]

Like any other tube in the world, draw it back a bit after you pressed out solder and it will not leek out from the tip. Then you can leave it on the bench or in a cup or what ever.

[@hightttech]

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.

Hi Alex great informative video as usual ..but im glad to see big boss in all his glory a very competent tech as yourself

[@tonyhallen1062]

Syringe -- Put a weak spring on the syring plunger so you have the plunger moving backwards once you are finished. This will create a negative pressure on the flux so it won't be costantly pushed out.

[@InssiAjaton]

I have seen a few KZbin postings where they have found a problem with the battery internal protectors, or the relationship to the charger protection limit. If the battery is discharged even a little too low, then it may refuse to take any charge. Their remedy seemed to be to force an initial charge to bring the cell charge above the critical level and then the charger started working again.

[@georgegonzalez2476]

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.

Our surringe is wrapped with aluminium tape and a magnet in between. That way, we stick it on a side of a bench power supply or hot air unit with needle up. We also do that on our soldering station, which doesn't have a holder or there is no space for the holder on the desk. Hope it helps

[@antekpc]

Hey Northridge Fix, I had a quick idea maybe you can use magnets to keep your Flux syringe stored while not using it. Maybe hot glue a tiny little magnet to the syringe and you can keep it upright held in place with a magnet with the needle facing up? Just a thought, let me know what u think and if it might work. - Anthony

The display may not working when the customer brought the motherboard. It's not because you replaced the charging port. Unrelated issue that has been there that the customer, either didn't know or didn't disclose it. When customer come with specific task, like replacing the connector or only fixing the board with charging problem, we only fix that specific problem that the customer's ask based on their diagnostic. The customer only want the bathroom repaired, meanwhile the roof is leaking. So we only repair the bathroom, not the roof. Unless customer want to fix the whole house, including the bathroom and the roof, we will approach the problem differently.
