    The facelift 7th generation Accord features an upper LCD display on the centre console section just above the centre vents. This displays, the time, cabin temperature setting and audio track information.

    It has been reported that over time this display will develop an issue whereby the LCD will occasionally flicker and even go blank, with just the back light illuminating a blank screen.
    If the top of the centre console is tapped the display can be intermittently restored.
    Several members have reported this issue and it would seem it is a common problem on this generation of Accord.

    A few members have performed some diagnosis and came to the conclusion that the main input connector requires re-flowing/re-soldering.

    I did not initially perform any of the diagnosis, that credit goes to the following member:

    Equipment Required
    To get started here is a list of some of the tools you may require
    -Interior plastic trim removal tools (available cheaply on ebay)
    -Pozi and flat head screw drivers (several sizes)
    -Good quality soldering iron and soldering lead
    (I used my Weller WSD81 soldering station)
    Parts Required
    No parts are required
    The Procedure
    Step 1
    Begin by removing the top centre console. In order to remove it, place a plastic interior trim tool on the lower section of console. The section in-between the console and the sat nav system.



    Gently pry out the centre console, it should easily pop out, repeat this on the opposite end and the whole console should lift away. Be careful not to damage or scratch any external surfaces.
    Before you lift away be aware that there are cables attached.
    (Be careful where you place the console to rest, it does have sharp edges and can scratch up your dash board if you're not careful. Place some rags or thick cloths for the console to rest on temporarily.

    Pics below show locations of the clips and connectors - It was much easier taking a picture after the console was removed. Hence why the pictures are of the console on the floor turned upside down.
    Remove the GPS and luminance sensor connectors from the front end.


    Then remove the cable tie mounts, one on the side and one towards the front. These can be quite tricky to remove.


    Here is a close up pic of the cable forward cable tie mount which is tucked just above the hazard light connector


    Disconnect the Hazard light connector - Shown below with an ARROW.

    Once the above has been performed, the console should lift away freely

    Step 2

    Next step is to remove the LCD display assembly itself.
    It is held by x2 pozi screws.


    Once the screws are removed the display assembly can be lifted away from the console

    Step 3

    Next step is to remove the rear cover of the LCD display, to do this use a flat head screwdriver and gently apply pressure to the clip tabs shown by the red arrows in the image. The rear cover should easily pop away upward.



    It is not recommend to remove the main plastic front lens of the assembly as you can attract dust etc into the display. Unless it is absolutely necessary i.e debris has got inside or the display requires cleaning, it is not recommended to disassemble this part of the display.


    Step 4
    Once the cover is removed you are presented with the rear of the PCB assembly.
    The focus is on the main green input connector.

    In order to gain access to the terminal pins the green connector housing needs to be lifted. It does not need to be completely removed (if completely removed it may be difficult to re-install) but you just need enough clearance to get a soldering iron to the terminal pins.

    Use a small flat head screw driver and gently pry the base of the connector. Apply pressure in a lifting motion on all sides of the connector to gently raise it from the base.
    Work your way to a larger flat head screw driver to provide more lift.


    Step 5

    Once the connector has reached sufficient height, the terminal pins are revealed.
    As shown below, it is clearly apparent that the terminal pins do not have sufficient vertical solder fill, thus resulting in an intermittent contact to the PCB pad.


    Here is a close up of the terminal pins

    close up.

    During manufacture, it may have just had enough to pass quality inspection and final test. Then over time, the solder connection will become brittle and crack causing intermittent connection.
    This is only a theory and has not been proven.

    Step 6

    To rectify the intermittent LCD display, all terminal pins are required to be re-flowed. Apply a good amount of solder to all pins and hold the soldering iron on the terminal base for a few seconds to allow the solder to flow nicely down the PCB pad and the underside of the PCB.

    Due to the way the LCD is constructed, access to the underside of the PCB is not possible unless all the display pins are de-soldered. This is not recommended.
    Once all the terminals have been re-flowed it should look like this


    Step 7

    Due to the extra layer of solder on the terminal pins
    (dependant on how good/neat your soldering is)
    the main green connector will not completely sit flush to the PCB. Push the green connector housing down as far as it will go.
    Do not force it to go any further as you may damage the pins or PCB pads.

    Step 8
    Re-assemble the LCD display back into the centre console and re-install it back into the car.
    Reverse of removal.
    Your flickering/blanking display should now be resolved :Smile:



    -Do not attempt to de-solder the main LCD display, the terminals are covered in some sort of conformal layer or RTV coating which will be difficult to remove without the proper chemical agents.
    -It is not recommend to remove the main plastic front lens of the assembly as you can attract dust etc into the display. Unless it is absolutely necessary, it is not recommended to disassemble this part of the display.
    -Do not attempt to remove the PCB, this is held in place with the soldered terminals of the display.
    -When fastening the screws to reinstall the display assembly back into the centre console, be careful as you can easily cross thread the screws in the soft plastic.

    Many thanks for reading and I hope this guide has helped you :Smile:

    Superbly detailed write up as always! I am sure many Accord owners will find this useful and it makes me think that the flickering LCD on 8th Generation Civic might be solved using same procedure.
