No video on the LCD
Hello,
Im from Chile and bought a Dell XPS1530 with 8400GS as the video chip, it worked for like... 1 month until it didnt show image over the buil-in LCD of the Laptop.
Here is what i did, just to know about some problems with the microfracture of the soldering material, but looks like this isnt the case. The Laptop works great if i attach an External Monitor over the VGA port.
Did _shot_ de videochip with a heatgun and press it against the motherboard, but it still have the same issue, no video on the LCD but it does over the VGA port.
A week after that a friend of mine borrowed his XPS 1530 to see if the faulty part was the LCD, but it wasnt, my LCD panel [cable and everything] worked fine on his XPS, and his LCD panel [which is working] didnt show anything attached to my XPS.
No idea what to do next and no, i dont have warranty anymore, if someone have a clue of how to fix this would made my day, week and probably year.
Thanks in advance from Chile.
Esta é uma boa pergunta?

+1 for excellent and brave troubleshooting with the LCD panel.
? If the VGA port is working, isn't the 8400GS video chip working also?
It could be a cold solder joint, not microfracture for the LCD outputs of the 8400GS or the LCD main board connector. This might not show.
Sorry you are having this hassle, keep posting what you learn. This is an interesting problem.
