samsung note 2 gt-n7100 dead. Not recognized by pc - GSM-Forum

bollicine · 09-03-2015, 18:56

Hi!
I have a samsung note 2 dead . It was charging the battery and fell . Glass damaged and the battery is coming out . Now No led , no sound . Not recognized by PC. I inserted jig , battery recharged externally , but Odin does not recognize it . Test with SD Card ( bbotloader of S3 as topic of this forum ) , shorted R319 , inserted battery and jig . I do not see anything on the display ( perhaps it is damaged as glass ) , nor it is recognized by pc kies or odin . There may be a short circuit on the motherboard next to the flat of the charging connector ? With jig inserted heats the part of the SIM card and SD card . Who will help me in the test and measurement ? I have a digital multimeter , no box or regulated power supply . Thank you. Those who follow me step by step ?

please help me!!
A question: in youtube's video the man ago a short circuit with a tweezer but the resistance isn't R319. What's and why he does after changing the EMMC? Does anyone know answer? here link of video

thanks for help!
I'd like to understand the problem on my samsung note if you can help me.... to look for a short circuit! I don't know and I'm not so good! it might be the resistance marked in the picture? with multimeter, in test diode, the resistance sounds! what does it mean?

with digital multimeter when i press power key i see 0.13A. If i don't press power key, it's on 0.00A and 5.23V. What do you think? u501? u500? what's i can check?

Check u500 output on this capacitors
Check and Mesure coils on buzzer mode if cracked and replace
Check and Mesure capacitors if shorted or cracked and replace

Is it right? the capacitors to be controlled are those in figure ? I must connect the USB cable to notes 2 and measure with tester !is it ok? I haven't more power over the counter ! thanks for your help!

habibboxes · 01-17-2016, 18:50

No need to connect USB cable
It's the exactly location of capacitors Check voltage on them like schematic show while keep pressing power key
If there is a different in voltage mesuring on capacitors then the problem is from the u500 ic and you need to change it
If voltage mesuring on capacitors is right like schematic show Mesure this capacitors on buzzer mode out of circuit

i mesure without the power dc insert and without battery? i mustn't power it?

habibboxes · 01-17-2016, 18:58

Yes you must so that can give you reading

bollicine · 01-17-2016, 19:07

exactly but I have only its USB cable and power supply! i've charged its battery externally!

habibboxes · 01-17-2016, 19:10

You need battery or power supply no other way

bollicine · 01-17-2016, 19:15

i know it! ok, i check those capacitors with battery in buzze mode! let you know!..i don't think a boot damage but a cracked transistor!

Oh, that's frustrating! But good diagnosis, indeed!
