    Hi guys,

    My MSI GT740 Inverter that powers the backlight has decided to go faulty on me.

    Problem is i cannot seem to source one of these inverters anywhere :(

    Does anyone know where i may be able to obtain one from?

    Thank you in advance for the help :)

    cheers,
    Gav

    I have no idea what that means in terms of compatibility.

    I would check ebay from time to time.

    it would not hurt to try a inverter from another MSi laptop using the same size screen, as long as the BIOS reconizes the inverter it should work.

    it can be hit and miss tho.

    Might not hurt to try another inverter entirely.

    I would be interested in buying the laptop from you however!!
    You could keep the graphics card and LCD screen. You need 2 more posts to PM, then I will happily take it off your hands! :)

    Sometime no backlight on lcd is not connected with inverter board ;). I have repaired almost 5k of NB MSI so I know them very good. There were some cases with mainboard damage (on mainboard is small chip controlling backlight).

    Dear majster msi, I have purchased MSI GT740, and now I have a BIG problem- therese a problem with the backlied- the screen is very very dark. I think this is caused of this small chip on the mainboard. Can you tell me more about this chip , so I be abble to reapair/replace it. I'm also very familiar with the laptops, but not in deep details about MSI. Thank you in advance.
