iPad 5th Generation VCC Main Short - No Power - How To Find A Short Thermal Cam - Injecting Voltage
HTML-код
- Опубликовано: 19 окт 2024
- Finding a short can be a little tricky sometimes, but in this video, I'll walk you through the whole process of detecting a short & injecting voltage to find it.
We use a Seek Compact Pro + our Macro Lens to find it.

First step is to plug in the USB charger & observe what does the USB Charging current show. A working device will show about 1A or more
Then disassemble & disconnect the battery & check USB charging again.
Run a Tristar Test to see if it shows a Tristar fail

Then probe the caps around PMIC and see if you find a diode mode reading of 0.000V. If so, you have a short.
Then inject 4.3V/2.5A into VCC Main & use the thermal camera to see what heats up. It is usually a shorted capacitor that will light up in the thermal camera.
In most cases, you can just remove it. In my video, it was a very large capacitor, so I replaced it from a donor board.
Then test USB Charging again & see if it boots up.

I hadn’t seen this method, just the method of soldering a wire to a point on the line and then injecting voltage. When you explained that wherever you inject the voltage it’s going to go to the shorter component since it’s the easiest path to ground really helped things click better. Thank you
That's great to hear! Glad it helped
I love the intro and the overall professional format!
Thanks man! Appreciate the positive feedback!
Great video! Loved the breakdown of the procedure. This is very valuable information, and it goes a long way if used correctly!
Happy to hear that!
Keep up the good work bro. Nice video !
Thanks bro!
Nice Work. Thanks for the video Jesse
Thanks for watching!
Excellent stuff my man 👏🏾👏🏾👏🏾
Glad you enjoyed it
Owie test.
That works too!
Well Done! Enjoyed the video.
Glad you enjoyed it! Appreciate the feedback!
nice breakdown bro great info
Appreciate it bro!
Great stuff as always Jesse !
Thanks man!
Great as always
Thank you! Cheers!
Great video, thank you so much! Question though... what is the difference between injecting voltage and just plugging in the cable? 5:41 And does injecting voltage to any of the shorted caps heat up the actual faulty cap?
injecting voltages into VCC MAIN is injecting into the shorted line
USB charging cable is not VCC MAIN & has other circuits in between that line, so it doesn't have the same effect
Great job
Thanks brother!
Another great video as always👍👍
Thank you! Cheers!
Thanks, well explained
Glad you liked it
Great video 👍🏻
Thank you 💕
Thank you
Can we follow same procedures on iPad Pro?
Same concept applies to all iPads
Awesome 👍
Thanks 😊
Any cons on leaving low melt solder in the joint to give back to customer?
Never had any issues with it
Good job
Thank you! Appreciate the support!

Hello!!
Which preheated do you use ???
A perfect short won't make heat though, I would have also mentioned that.
What do you mean exactly?
@@VCCBoardRepairs A perfect short circuit will pass a lot of current but since their is no voltage drop it will not get hot.
I'm not sure what you're referring to. Anytime I've dealt with a short to ground, there is always heat generated through the shorted component.
In 99.99% of cases people will deal with, this is what they'll see.
I'm not going to comment on the random or oddball 0.01% chance of some scenario where something doesn't heat up with a short present
@@VCCBoardRepairs the same exact info is in the Rossmann repair manual if you have studied it. Well it does happen from time to time. But I would say active shorts are more common than shorts that don’t cause any heat cause you are right most shorts do produce heat.
is that a short on a diode?
Actually, it's a capacitor
What’s the app your using on your pc to look at the schematics

What usb charging meter are you usung on the screen?

iPad 5th. Generation fix
Yes, this is an iPad 5th Generation that is now fixed.
@@VCCBoardRepairs lol it sure it

huh?
Great video 👍
Thank you!
