i dont have the schematic, i received today one of does models , with entire 19 volts in short , even grafik cart was getting hot just by plugin in the dc source ..!!!
found the first mosfet after dc jack was totaly shorted , replaced and still problem on board . found a mosfet also getting very hot near the LVDS connector , does boards are not marked so i cannot mention with PQ it is , i can say its a4927N ( in this part of the circuit there is 6 mosfet each one close to the outher
__ | | S
__ | | (this is they're position D__S (for both) | (for all 4 as well )
D
SO the __ bottom is out of board since is shorting the line , removing it , board start up and go directly to EFI bios , since there is no hdd in the moment , my main question is , i dont have this schematic and would like to know what this mosfet will feed ?
would be nice knowing , meanwhile im gonna find some compatible mosfet to put instead of this one , since i dont have this one in stock .
i receive the same board , but mine have 3.3 and 5 volts ok , but once i insert the 19 volts on the DC in , the HM65 start getting hot like hell .. since i dont have this schemtic or board view , i noticed that the coil next to the PCH , is with around 3 ohm resistance between coil and GND... not considered as short but a very low value , i lifted the pch and i have on the same coil 17Khm , i replaced the HM65 , still getting hot once i insert DC in ..
any ideas ?
ohh didnt noticed i had this board before and just now i noticed my previous post .. this is another board not the same mentioned on the previous post !!
Weird shit the HM65 getting hot just by pluging in the ac adapter.
sorry wrong place , since i got 2 board the k53sv is a completel DEAD board by someone why have brushed the board with a iron brush to remove the oxid frmo a water damage !!! BIG LOL ...... mine is a k54l , will open a new thread
