    burned mosfet wich has written on top "I6 GUE 8v1507"
    by Caly411
    Hi, Im having a similar problem with my Acer Nitro 5 AN517 52, took it to repair and they said that the problem was a burned mosfet wich has written on top "I6 GUE 8v1507".
    There is written PQB12 on the motherboard right next to it.
    Does anyone know if there is soemthing similar I can buy to replace it with?
    Seems impossible to find theidentical mosfet online.

    Philips 42pfl6008s/12 red led comes on for a second and then goes away but 3.49v stay active
    by Malcolma172
    I was trying to repair my tv wich previously had a blinking red led 2 times and it kept going. After shorting the sdm the blinking led changed 5 slow blinks and 3 fast ones wich in the service manual meant error 53 / the fusion chip.
    After I heated the fusion chip with a hairdryer for 5 minutes it started working perfectly but after a day it stopped this time no led blinks even in sdm mode.
    After probing the psu I have 3.49v and for 1 second I have at least 2 12.3v lines active the fusion chip gets warm in that second the led turns on and then the 12v lines start losing power...

    HP Elitebook 840 G1 BIOS Issues
    by Larchemont
    Hello Folks,

    i have a HP Elitebook 840 G1 with a locked BIOS and i have bought a CH341a (black PCB). My problem is that the Bios Chip reads 25Q128A 13ECO and i cannot find a profile for this chip in any of the software recommended in the guide threat in this forum. The chip cannot be detected wich i dont find too surprising, but i can read the chip with random other profiles selected.

    I have found a post in this forum in wich the user stated he was able to flash this exact chip with the CH341a and the testclip, but unfortunately this user is no longer active. In...
