Hm that is something I have never really considered. In fact, I think I may go ahead and break some on a known good cpu and see what lines become short. Good idea.
@@iBoardRepair yeah some tech thing that crystal are ic but not, they are DTC capacitor, when you use the pen grinder you dont have to put the cpu flat , just remove it, put some tape around and take your time to remove it.
I take my cap off for you guys fix phone so small micro scope components what is the secret to desolder and solder micro SMD I tried it with my iPhone and now it's worst then it was
Short killer is for VDD MAIN. It wouldn't affect the CPU. Also, the voltage is low with high amp on the short killer. It is likely the CPU was damaged and caused cross circuits. It happened often.
@@vincen.3590 99% of people who own a short killer inject voltage on any line that is shorted to try and burn out the short hence the name "short KILLER"... using a normal DCPS you can inject enough amperage with the correct voltage into almost any circuit to see where the failure is. Especially if it is a line like VDD_main. Short killers are one of the worst gimiks in the market for inexperienced techs. Can you image putting 10 amps through a via in the middle of the board that is 1/4 the thickness of human hair? The damage you are causing with that "tool" is just a ticking time bomb if you actually find a shorted component with it. I have seen some dumb famous youtuber inject 3V into a CPU line on some random computer and 100% the CPU was dead after that. 1.8v or 0.8v lines don't like 3v. Its funny, because on his video you can also see what looks like support components heating up in his thermal camera. CPU was probably fine, but not after he touched it with a short killer.
Very professional. One of the best repair channels I’ve come across on RUclips.
I really appreciate that!
great diagnostics - love your videos and your descriptions into who, what, which and why, is just first class.
Really appreciate you watching!
Where you changed the first chip it was 2 capacitor that was connected together and shorted i think that was the problem you can check your video
Those are both ground, so it is okay.
Another excellent video mate
Thanks for giving it a watch!
Good job !
I really like watching Your repairs;)
Thanks for watching!
hi sr, try to remove the dtc capacitor on cpu( use a pen grinder), maybe dtc capacitor are shorted

I agree with you sir.

hi again what barlow lens you refer for verry small smd caps
I use .5 barlow lense
Video is awesome one actually!
Thanks a lot for watching!

Thanks for watching. Thousands of hours of practice is the secret!

Ahh man I wish that other shop didn’t butcher the phone. Unfortunately it was for sure unrecoverable way before you laid hands on it .
Yeah, threw me on a goose chase for awhile

With that quality of work, I bet they probably had a “short killer” and started injecting…. Poor CPU :(
That is a good point, who knows!
