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 2 года 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 2 года 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.

@RogerTannous 2 года 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.

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 2 года 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.

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 Год назад

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.

I have seen a few RU-vid 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.

@antekpc 2 года назад

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

@MrMath1973 2 года назад

I had the same idea as you had about the magnets. theres some holder for knifes on some kitchens and he could adapt same thing like that to keep the syringes pointing up.

Keeping syringe clean...I just always pull back a little on the plunger to release the forward pressure on the flux and that stops it from dripping out. Hope it may help you all.

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.

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.
