Besides HP parts (they have a parts division) is ikenfixit.com and notefix.com
The Backlight Inverter in my f70 needs to be replaced. The Inverter I've found to replace it is the 48.L2603.B00 Inverter for 4 CCFL Lamps Module.(http://lcdpart.com/Products/48l2603b003.html). However the inverter in the monitor has the part number 48.L6202.A00 and its shape is long and L shaped, unlike the square shaped one shown on the website. I'm not sure what to do about this and any help would be really appricated.
