| Hi all. Have a DV4 for my wife that I literally got from a friend - decided to give my wife after fixing up. Realized that the screen doesn't come on and after opening it up it seems like a resistor is burnt. Problem is that I don't know the value or the number on the board. Any help finding this would be greatly appreciated. Just need the number by the resistor and what's on it so I can try and look it up. Thanks in advance! http://s162.photobucket.com/user/khat17/media/DSC08276_zpsf1ed388b.jpg.html http://s162.photobucket.com/user/khat17/media/DSC08279_zpsd3722836.jpg.html http://s162.photobucket.com/user/khat17/media/DSC08278_zps2099e938.jpg.html http://s162.photobucket.com/user/khat17/media/DSC08277_zps60ba6049.jpg.html The full model of the laptop is DV4-1548dx. Motherboard part number I believe is JAL50 LA-4105P. |

| So since nobody replied I've done a bit of checking and decided to try something. The missing resistor on the RIGHT in the LAST PICTURE was replaced using a 3.9 ohm resistor - I wanted to get 3.5 but couldn't. Since I've done this the laptop screen has been working without an issue. It should be noted that though the resistor on the LEFT of the missing one is burnt I tested it and got 3.5 kilo-ohms from it. I need to do some verification and pics will follow later on. Maybe. Since it's already assembled and such. |
