Re: foxconn v181 mbx-272 schematic

This netbook has a blank screen problem, I've tried to flash BIOS but the problem still. already tried to replace it with a good RAM.

several measurement points, among others:

PL38=1.09V
PL39=1.5V
PL31=1.0V-1.3V its look like wierd ?
PL34=0.9V

without a schematic, it is very difficult to trace

Re: foxconn v181 mbx-272 schematic

reflow done?

Re: foxconn v181 mbx-272 schematic

reflow done?

thanks for reply.

Unfortunately not, because I have not had a BGA machine. try this week asked for help by a friend who had a BGA. I hope this can solve the problem

"PL31=1.0V-1.3V its look like wierd ?"

check this again and try to start only on battery

Re: foxconn v181 mbx-272 schematic

for comparison I used a schematic acer quanta zhg because both use the IC OZ8380aln.

on pin 9 LX2 measured resistance 13ohm, while the pin 16 LX1 146ohm. for a processor that can not be removed like this netbook, how should the coil resistance ?. This direction towards NBcore

before reflow motherboard I want to make sure nothing is short

Re: foxconn v181 mbx-272 schematic

problem solved

before reflow, I think and analyze again.
try to power netbooks, touch the cpu and chipset and feels warm, meaning the cpu and chipset are already working.
*
during the search for the schematic, accidentally discovered this tread https://www.badcaps.net/forum/showthread.php?t=41172. I finally decided to once again flash the BIOS with the file. and it worked.

thanks for badcaps, specials for dycc

Hello techs,
Does anyone have the MBX-272 V181 schematic?
I have a problem with rezistor in photo. (attach...)
Thank you...

Foxconn MBX-272, This platform have no schematic

Re: foxconn v181 mbx-272 schematic

OK, does anyone knows what resistor is that?
If anyone have the netbook to measure the resistor?

SOS is the only problem and I cannt fix it!!!!!

Re: foxconn v181 mbx-272 schematic

Hi,

That resistor is 0.00 Ohms.

Re: foxconn v181 mbx-272 schematic

Hi, I think I have the same problem, may I know how you flashed the bios? Anyway to do on the board or I need to unsolder and flash from computer, I have the following flasher, but I've not used it, I will research now online:

CH341A 24 25 Series EEPROM Flash BIOS DVD USB Programmer

I got it a while ago but never tried it. I have all the equipment to unsolder it.

Cheers

Re: foxconn v181 mbx-272 schematic

I figured this out now, for anybody else follow this video:

You can buy the programmer off ebay for around 3£.

I re-used the chip after erasing it and seamed fine.

Cheers.

512 ohms

thanks i put 510 ohms its working
