Worlds Best Socket 7 motherboard Repair , IC HOT
Hello , i have a FIC PA-2013 motherboard , i wanted to put in a new system, the board was working fine for 30 minutes , after that it started freezing and had to restart to make it work, and made a squeeking noise at the cpu capacitors ( the small SMD capacitors in the middle of the socket ) , suddenly the cpu fan stoped and turned on and did this a couple of times , after that the cpu fan socket ( 3 pin ) wasnt recieving 12V , so i had no more cpu fan spinning , after that the board just froze and died .
Now the motherboard wont post at all ...
So basically i identified a mostfet...Last edited by Roli; 02-12-2021, 05:08 PM.

Burned IC on a Gigabyte Z390 Aorus Master
Hello, today i managed to ruin my motherboard, its a Z390 Aorus Master from Gigabyte, basically what happened is that i wanted to test a videocard that had 2x 8 PCI power pins , so what i wanted to do is power up the machine with 1 power supply for the processor and the motherboard , and one power supply just for the graphics card ( 2x8 pci pins ) , so when i powered on first the Psu for the 2x8 pins , it shorted out a mosfet.
Ive checked everything with a multimeter and seems fine, also checked the southbridge and its fine , but the problem is i cant read what it writes on the little chip...Last edited by Roli; 01-16-2021, 07:50 PM.

Re: Acer 8943g shorted motherboard with LVDS connector
I will have to order it from china , it will take like 2 months because i dont have one , on this N184H6 display , there is another ic , it is not hot or anything , but im afraid if i order the RT9921 and change it , maybe this other ic will be hot to and i want to order that also because i dont want surprises , so on the other ic it writes DW=BK W16 , what ic is this ?
Attached a picture...

Re: Acer 8943g shorted motherboard with LVDS connector
The model number is N184H6 - L02 Rev.C1 , posted picture .
So basically i need to order a new chip and reprogram - it ?
If yes i have only 1 programmer , TL866 , need to check if it supports this chip ...
Or are there any other ways to program this ? Maybe using paralel port or serial port ?
And where can i get firmware for this ?...

Re: Acer 8943g shorted motherboard with LVDS connector
Ok i managed to change the resistor , the display still wont start , ive managed check an IC marked as : S24C02 , its a 2Wire serial eeprom , donno why but its verry hot , and its shorted to ground ...
I think i am going to remove that and check if it works maybe without , but i dont think so ...
