hi
im looking for people who have the gv-n105toc-4gd gigabyte
to look for those components
shematic and boardview welcome

need to know those values
c 671 678 684 693 815 825 824
r 634

ty

Re: help repairing Gigabyte gv-n105toc-4gd

Capacitors should be 0.22u 6.3v on the pcie lines

Are you sure it's r634? Looks like c825 that's missing on the 2nd image or is r634 open circuit?

thanks

ure right but wanted to know the value just to test and verify...
825 is missing
possible same value than 824 ?

will change the 3 capacitors
wanted to change them but my iron heater is not adapted too
so i wait my air thermal to do the job

This boardview should work

hi
im really glad
as i suposed same model except ram values

normally got all to maintain it !!!

Re: help repairing Gigabyte gv-n105toc-4gd

Yeah, that circuit looks identical

hi
ty again
just a question how to identify by see the value of voltage of cms capa ?
must find replacement on "giving cards"

Re: help repairing Gigabyte gv-n105toc-4gd

If it doesn't say then you need to guess from the circuit that they are part of and allow some room for error - what voltages are expected on the inputs etc.

For instance, C825 shows as being connected to 12V_EXT6 and GND, so the cap needs to at least work with 12v (so aim for 16V)

well ty for answer but wasnt the point of the question lol

how to reconize a 6.3v than a 16v cause no marks on it ?
just the size ?

other question is what temperature components supports ? i suppose heavy ones not to burn on rohs....
and should be high cause made on ceramic

in other hand what temperature ti use to dismount them by air and what on iron to mount them

Ah sorry, I misunderstood.

If you are pulling components from another board then it would be helpful to have a schematic for that board as well, otherwise its hard to know.

thanks...
they could do differents colours !!!!
i recover comonents from many boards....from differents functions.... so dont have any shema

other question
does c674 678 684 693 missing makes the pc unbootable ?
this card is strange...
no booting pc but if u does it by motherboard chipset u can turn it on by windows perephicals (dismount and remount)

my daughter said she saw like a flash gpu side and near outputs...
i suspect her adaptor hdmi->vga to had a pb and makes a component blow

l19 seems to get hot
and c822 seems to have a crack on it
will try a photo

Re: help repairing Gigabyte gv-n105toc-4gd

here they are

Re: help repairing Gigabyte gv-n105toc-4gd

perhaps a short on q13 or q14

[klendatu]

Re: help repairing Gigabyte gv-n105toc-4gd

perhaps a short on q13 or q14

r7093 et 7094 are fine

i will dismount l19
when i mesure between the 2 sides goes 1 execpt at 1 point goes 0
think maybe the solder broken at 1 side
it will explain the flash...

Re: help repairing Gigabyte gv-n105toc-4gd

perhaps a short on q13 or q14

maybe ure right the 6508 seems to get hot
some marks around
gonna do a picture to get your pov

continuity around l19 and c822 seems ok
will redo solder for L19

Re: help repairing Gigabyte gv-n105toc-4gd

q13

how may i verify it ?

Re: help repairing Gigabyte gv-n105toc-4gd

This boardview should work

Hi!

I´m try this boardview but isn´t valid to my graphic card.
I have gv-n105tg1 4gd.
Some parts are similar, but the part I need is not quite valid.
In my case, the fans and the fan stop led do not work.
Is it possible to get the board view?

Thanks!

hi
otherhands does the card works ?
if it does u can try to reflash the card...
did u try msi afterburner and try to use your own def for fans ?

Re: help repairing Gigabyte gv-n105toc-4gd

q13

how may i verify it ?

ok found how to test it
so ive got 1.3Mo beetween 3-4 pins
so the mosfet is good

am i right ?

im quite sure the unworking of that card is only missing capa at pcie rail.....
just waiting a capa test to find some to put in place

[klendatu]

Re: help repairing Gigabyte gv-n105toc-4gd

q14 got 1.7Mo
