what is the point of R1 resistor on ps4 slim ADP-160CR power supply?
I am looking at the schematic and i dont understand why is it important to have a 0,1 Ohm resistor. Does it have to do something with the 2 mosfet (Q3 and Q4) in series? What if i just replace it with a wire? thanks -
nah. fixed it. 0 ohm resistorsLeave a comment:

No video output on Nintendo Wii
Hi everyone!
I have this wii that has no video output on composite nor on the other RGB coloured rca (forgot its name).
when i plug the power the cd reader makes noises, i can press power button it turns from yellow to green , i can turn it off with long press. If i press eject button it makes noises.
Checked the coils for voltage all are present. AVE chip gets voltages, no short on board, cpu heats up warmly. Tried pressing reset button then power, nothing happens.
Checked voltages on Y, Pb, Pr pins i get some readings but i get nothing on Composite... -

Asus N501JW - EC programming help request
Good Morning everyone!
I've got this laptop with a shorted EC - IT8585VG. I have the RT809F programmer and i have no idea how to programm the EC.
I've found a video online about this but quality is so bad i cant see anything.
Tried to do with flex cable to the keyboard connector with no luck.
Didnt find any pinout/datasheet for this chip. Checked older posts, nothing
Found some other post on vina, unfortunatly i need to pay to see the pictures.
Anyone could help me in this?
Thanks -

samsung 530u3c-a01uk bios request, becuase linux live usb bricked it. thank you
Hi!
I am requesting a bios for my own laptop samsung 530u3c-a01uk or p03aaj ba92-10452b.
I've lost bios when i tried to install ubuntu. I've read somewhere that this model can get bricked when installing other OS.
I've read the original dump with an ezp2020 reader (ch552g) probably corrupted.
thank you... -

Asus X507MA schematic request for side project
Hi!
I am requesting a scheamtic for this model, because i want to convert a touchpad to an usb one.
I have a dead huawei laptop and its keyboard and touchpad feels good.
Looked up what chip is on the touchpad and it's used buy other brands too. Like Asus.
All i need is the pinout.
As the motherboard is dead i cant measure anyting. Found Vcc and GND but it has 8 pins so i am missing 4 more. Looked up some other schematic and they all go into the EC.
Thank you -
Re: Can i request bios for Huawei WT-W09?
Thanks!
I just flashed it and same thing just like before.
Removed the RAMs and same thing.
My final guess is CPU.
Thank you for postingLeave a comment:

Re: Can i request bios for Huawei WT-W09?
Thank you!
Unfortunalty it did not work.
motherboard pulls 500mA for a second or so at 20V then goes back to 70mA.
All the voltages present for a second at coils except one, i assume it is for internal GPU.
It charges battery.
my final guess is either cpu or ram damage. At this point i have idea what could be. Checked the board for short but there is none.
Thank you for the bios file.Leave a comment:

Re: Samsung ue40j5200aw - Replacing chip on the T-con board.
You mean the LCD panel itself or those Ics on flex cable that attached to the panel?Leave a comment:
