HP G7 LED display problems - not the inverter
I am working on a HP g7-1167dx Windows 7 Home Premium. The LED display backlight keeps turning off after a few hours with images. Then comes back on randomly. External monitor connects fine. No inverter on this computer, replaced complete LED screen twice and still same problem. Reinstalled drivers and updated BIOS as well. Only thing I can think of is a bad cable from the motherboard to the screen but is just real random when it turns off. Screen will light up by itself after 5 - 10 minutes, usually on restart will b fine. Any help would b greatly appreciated. No errors detected. Can anyone think of anything else to check before buying this cable. Running out of ideas.
