I am writing this thread for my Dell Inspiron 700M laptop. I know before replacing any part it’s better to make research on it that what is exactly giving problem. My laptop display is not working but I am able to see my display on external monitor after reading some guides. I was thinking that my display has damaged but when I made search on Google then I found that its backlight problem and display is working. Suddenly it came back again just for 45 seconds. I remember it will work just for 45 – 50 seconds when I will open my laptop. I do not think that it is happening because of some lose connection. Maybe it is happening because of overheating issues or may be something has been shorted and making runway positions and protection circuitry is triggering. Is anyone has experience about this problem? I read somewhere that some people has been changed there back board bulbs. I think so problem is inside my inverted board. Please give me your suggestion. Thanks in advance.
