    I replaced the LCD screen on my M5010,the laptop only beeps the screen doesn’t light up

    • What was the reason for replacing the screen? Was it doing this before? If not, I would suggest double checking all of the laptop connections. LCD cable, keyboard, re-seat the memory, ect.. Pretty much anything that was disconnected when you were replacing the screen. The problem will most likely be a loose connection.

  • Leonardo Feliciano

    I dropped heavy book on it,cracked the screen,it was stilling lighting up after accident but could n’t see anything so i connected laptop to tv and it worked for a few wks before loss of picture.I ordered new screen installed it and double checked the connections.The laptop is emitting an 8 beep code/display failure,does this mean I have a bad screen or the wrong one?Could re-seat the memory help. the set-up guide said check support.dell.com/manuals ,the manual said to check the set -up guide

    • The 8 beep code for display failure could mean the LCD screen, LCD cable, or the video chip on the motherboard could be bad. I would start with re-seating the LCD cable. If that doesn’t work, double check the compatibility of the replacement screen. The last option would be replacing the motherboard to make sure the video chip set is good.

    I have a Inspiron 1545 but my display assembly does not seem to have an inverter. Could this be true?

    • The Inspiron 1545s came with multiple screen options including a CCFL style (that uses an inverter) and a LED style (doesn’t use an inverter). If you have the screen removed you can get the Dell part number off of the back to confirm the type you have. I would guess you have a WXGAHD LED similar to this, http://www.parts-people.com/index.php?action=item&id=9782 but you will have to cross reference you part number to be sure.
