Asus K55a-hi5103d
Hi,I have a problem with the LCD. There is a light in the back of LCD but nothing is displayed. When I connect external monitor everything works well.Probably the problem is with the lcd inverter. Could you specify what model & part number of inverter is used in my Asus: K55A-HI5103DKarol

Usually it is one of these faults:
- worn out backlight, that cannot power on anymore with the supplied voltage
- burnt inverter board, not powering the backlight anymore
- broken cable in the hinge, not powering the inverter board anymore
But I have also seen laptops, where this was no hardware fault. Shutting down and powering on again sometimes helps. Also closing and opening the lid might help (in case of a stuck lid switch or a dizzy embedded controler)
Note, that a defunct backlight will not affect the lcd, so the picture will still be there, only with really low contrast. So your problem is a defunct backlight for sure. But this can be caused by more than one fault.
Thanks
