My HP notebook has no screen display and does not boot up unless connected to an external monitor when it then works perfectly (except for still no laptop display). My repair company advised that the backlight is ok but the inverter needs replacing. This they did but it's still not working and I am now being advised that the motherboard shows signs of water damage - could be condensation etc etc. Two questions. Why does it work fine through an external monitor and are my repair company trying to rip me off?
