I have a Dell Vostro 3550 that I booted up this morning and received 8 beeps on startup with no video being displayed. After reading the forums here is what I have done and the reults:
I am assuming I have a faulty LCD Screen and/or cable but want to be sure of this before spending the money as this laptop is no longer under warranty.
The 8 beep error code indicates LCD screen failure; the hardware diagnostics error code indicates that cable or connector issue. Try updating the latest BIOS using the link below
Please connect the Ac Adapter while updating the BIOS and do not interrupt this process until the system restarts completely. After the BIOS update run the hardware diagnostics again and check if the error code occurs?
If no error occurs then it´s a cable or connector issue. Please contact the Out of Warranty department 1-800-288-4410 (U.S.Customer only) In case you’re from a different region please get back to us.
