I have a laptop that my cousin stepped on, and the display quit working (in large part because its cracked). I have replaced the display and it still does not work. So I thought it must be a bad part (I get bad parts all the time on eBay), so I ordered a replacement, still doesn't even light up.
So I tried other testing: I plugged a 15.6" lcd in (the original was 17.1", but I tried the Lcd from my laptop) and it was solid white (at least it lit up). So some signal is coming from the motherboard. I also plugged in a monitor and tv to the vga and hdmi ports on the laptop, and it supports an external display fine. I tested the brand new displays on another computer to see if I may have gotten 2 bad parts, but they came on, but with a fuzzy picture and a pink tint. I have also replaced the cable that connects the internal display to the motherboard, and the results are still the same.
My question is, is it possible that this motherboard is damaged and just won't support an internal display? The computer runs perfect when hooked up to an external display, but I have not been able to get any internal display to work. What makes the matter more confusing is the brand new lcd screens won't turn on or light up at all when connected to this motherboard, but other displays (a known working display from my laptop, and an old broken lcd screen I had in the closet) both light up solid white.
I asked this same question about a month ago and nobody responded, but that was before I had tried a 2nd brand new lcd screen and replacing the cable that connects the motherboard to the display.
