17 inch monitor goes blank

  • Prepare to diagnose the computer .
    1. Disconnect all peripheral devices.
    2. Perform a Hard Reset.
    3. Disable the Automatic restart on system failure option.
  • Remove any non-system disc from the computer . During startup, the BIOS checks different devices to locate the Windows operating system. If the boot order is set to check the optical disc drive or the card reader (if the notebook is equipped with a card reader) before it checks the hard drive, and there is a non-system disc in the CD/DVD drive or there is a memory card in the card reader, the boot will fail. This problem can be resolved by setting the BIOS to check the hard drive first.
  • Reseat the memory modules . If you are getting memory errors, most BIOS versions have additional tests that can be run to test the memory. There could be a problem if one of the sticks is defective or loose in the memory slots. To determine what is causing the memory failure, disconnect all electrical power, and then remove and re-insert the memory modules firmly into the slots. Some HP Notebook PCs come with two sticks of memory and have two memory slots. On most notebooks, the memory module compartment is located on the bottom of the case, but the exact position varies by model. On some models, the memory compartment is under the keyboard. See your User Guide for the exact location of memory modules on your notebook.
  • Reset the BIOS to default condition . If you have made changes in the BIOS setting, such as disabling a device or changing the boot order, it could prevent the computer form starting properly. To restore the BIOS to its factory-recommended settings, turn on the computer and press f10 to access BIOS setup, and then press f9 to load the default BIOS configuration.
  • Perform a memory self test . There are different reasons that you may see a memory error. There could be a physical problem or it could be a program error. If the error is a program error, you will most likely see a Windows error message. If there is a physical problem with a memory module, the computer may fail part way through the boot process. Most computers have a built-in memory test to help identify if the memory modules are seated properly and are free of errors. To run the memory test, turn on the computer and press f2 .
    • If the System Diagnostics screen displays, select the Start-up Test to run the system memory test. Press the Esc key once the memory test is complete.
    • If the BIOS Diagnostics screen displays, select Memory Test .
  • Reseat the hard drive . If you get a specific hard drive error message on a black screen indicating the hard drive error, reseat the hard drive. If the computer has been dropped or jarred, or the hard drive has been replaced recently, the drive may not be seated tightly. The hard drive LED should blink if the hard drive has a solid connection in the notebook. Refer to the on-line User's Guide for specifics on locating and removing / replacing a hard drive. HP provides video directions for performing this task for many computer models. Remove and reseat the hard drive firmly into the mounting bracket.
  • Test the hard drive . If you get a hard drive error message, you can test the hard drive. Many computer problems are related to soft failures (or degraded performance) on the hard drive. The HP Hard Drive Self Test will repair soft errors on the hard drive, but it will not report the errors. After the test is complete, restart the computer to see if test repaired the problem you may been experiencing. To run the hard drive test, turn on the computer and press f2 .
    • If the System Diagnostics screen displays, select the Hard Disk Test to run the hard drive test. Allow the Quick and Long Hard Disk Self Tests to run.
    • If the BIOS Diagnostics screen displays, select Primary Hard Disk Self Test . Allow the Quick and Long Hard Disk Self Tests to run.

    Model - MFC-7420 - FUSER ERROR

    Is the paper that comes out of the paper warm or cool?
    If "cool", then the fuser is not operating.

    The job of the "fuser" is to generate heat to melt the powdered-ink into the paper, to make a permanent bond.

    So, take the printer to a qualified technician, for trouble-shooting.
