Hello everyone hope you are doing well,


i have a ddr2 I31GM4-LF REV3.0

it seems everything working fine except that USB,SATA,PCI Devices can not be read or detected by the computer but the strange thing that there's voltage present like the usb 5v and the pci 3.3v i believe its something related to the southbrgide chip.

as i know if the southbridge is faulty the pc will not turn on in the first place.


by the way i did replace couple cup's and rams and they works fine. and i did check mosfets and caps and they are good....

Hello everyone, i have an old acer monitor "AL 1916W"


it was totally dead but after i replace some bad caps now the led turns green and red when it's in sleep mode.

but the picture at all no backlight or a dim picture in the LCD.


i just wanted to know how can i test the backlight and the lcd or from where to measure the voltage going to the backlight or the lcd, to know if the problem in the psu or not.


i did test most of the component there if there's a short but they seems fine.
