HP Pavillion dv4 blank screen - what to replace?
Posted on 2010-09-10
I have an HP DV4-1114NR (FR931UA#ABA) laptop with nothing on the screen but the VGA externally works fine and it boots up into Vista with no problems. Shining a light I don't even see the faintest image that would indicate the LCD is working. Turning it on I don't even get a quick pulse of light in any way, either. As I said, once Windows would come up, I can't even see anything on the LCD that would show me it's working. What would I be best off replacing - the LCD, the backlight, or the inverter? From what I read I'd have to see at least something on the screen, albeit dark to suggest the inverter or backlight? I'm also confused as if some replacement LCDs (such as the ones you get on eBay for $100) include a backlight or not... If anyone has suggestions, links for what sounds like the best replacement part, I'd be very appreciative!
By the way, I've also read of crazy ideas suggesting to take the battery out for a while, open the display all the way out, hold in the power button for 30-60 seconds, then plug the AC back in and try it with no results...
