I work for a small computer firm and recently i came across a odd issue i received a dell studio 1537 with a cracked screen. after a routine screen replacement like the hundreds i have done before. i turned on the laptop and the monitor remained black. i verified that the inverter was properly connected and that the video cable was plugged in but still no result. the old LCD which while being cracked worked partially but now also failed to light up when put back in as a test. i looked online and i found an article regarding a few inspiron models that had a manufacturing defect in the graphics module. does anyone know if my problem with the studio 1537 is related??

and if so what is the next step replacing the entire graphics module ??

(side note) the VGA connector still works when hooked onto an external monitor

at this point in time i will suggest a new computer but i am most interested to know if anyone else has encountered this issue.

though i suspect that when said customer dropped the computer it may have caused some cracks in the mainboard or graphics module that just got worse when i removed the screws to take the computer apart

Since it works when plugged into the VGA socket there is no issue with the video subsystem. I would suspect much like you did that during the incident that broke the screen some other connection was broken from the board. The only thing I would suggest other wise is double checking all of the ribbon cables on each end as it may have pulled from the mainboard socket.
Get your facts first, then you can distort them as you please.

actualy the first thing i did when i encountered the black screen was remove the ribbon cable and replace it with a new one.
