Unable to power-on DVR+ or get it to display on my 4K TV. (Black Screen) (CM-7500)

If you are having issues getting your CM7500/DVR+ to display on the TV screen after connection, it could be a 4K HDMI compatibility issue.  This issue typically appears immediately after connecting your DVR+ to a new 4K TV(Typically Vizio and Samsung models). Symptoms of this issue when connecting a new DVR+ to a 4K TV are a black screen and no response to the remote control.  If the DVR+ has already been already set-up and working on another TV but are upgrading to a new 4K TV, your symptoms may appear as the remote control not functioning or you may be unable to see any of the on-screen menus such as the Guide, Menu, and DVR screens.

We have implemented a fix that resolves these issues in our 132R version of software.  If this is a new purchase, it is still possible that you could experience these issues because there is no a guarantee that the unit you received has been pre-installed with the newest software.  We release software frequently so not all DVR+ receivers will come with the newest software.

Here are the instructions for updating your software if you are experiencing this issue.

Options for customers with new DVR+ and/or 4K TV:

  • Option 1: Install the DVR+ on a non-4K TV and complete set-up wizard and connection to the internet.  After the DVR+ is connected to the internet, go to Menu>Settings>Technical Info>Software Update>Check for download. If new software is available, the DVR+ will download and install.  Once the new software update is complete, you can now re-connect to your 4K TV and it will display on your screen.  It is recommended that you do a factory reset once the DVR+ is connected in its permanent location.  To perform a factory reset, go to Menu>Settings>Factory Reset>Default Factory Reset.
  • Option 2: Install the new software on the DVR+ using a USB flash drive.  To install the software via a USB flash drive you will need to download the software file from our website, place it on a USB flash drive and preform a 'Basic USB Update' on the DVR+. While watching live TV, insert the USB Flash Drive into one of the empty USB ports. You will see instructions to on your TV when the USB Flash Drive is detected. (WIFI adaptor, Ethernet cable, and External Hard Drive must be disconnected prior to updating software.) After that is completed you can connect it to your 4k TV. 
  • In some cases, the USB Flash Drive appears to be incompatible and update fails. For instructions and video on how to do a Forced Software Update, CLICK HERE.
  • NOTE; If you only have a 4k TV, then the 'Forced Software Update' is your only option.
