Reset defender dvr sn301 resolution and the screen is not showing the dvr menu i set the resolution above the screen so i want to reset the dvr resolution to defult

If the menu is showing on the TV but the rest of the display is a blue screen, it could indicate a problem with the video output or the connection between the Onkyo SR875 receiver and the TV. Here are a few steps you can try to resolve the issue:

1. Check the connection: Make sure that the connections between the receiver and the TV are secure and that the cables are not loose or damaged.
2. Check the video settings: Make sure that the receiver and the TV are configured to use the correct video input and output settings. You may need to check the manual for your TV and receiver for instructions on how to do this.
3. Check the TV display settings: Make sure that the TV display settings are configured correctly. Check the TV manual for instructions on how to adjust the display settings.
4. Check the resolution: Make sure that the resolution of the TV and the receiver match. If the resolution of the TV is set higher than the resolution of the receiver, it can cause a blue screen to appear.
5. Power cycle the device: Unplug the power cord of the receiver and the TV and wait for a few minutes before plugging it back in.
6. Factory reset: If none of the above steps work, you can try performing a factory reset on the receiver. This will erase all the configurations and settings and will set the device to its original state. Check the user manual or contact the manufacturer for instructions on how to perform a factory reset.
7. Contact support: if none of the above

Im having the same problem did anyone show u how to fix it?

my dvr stop working could it be cuz my monitor is not working?

Hi,
Please reboot the machine. After it beeps hit F8 repeatedly. You'll get
a menu. One menu item will be "vga mode". Choose that, and use
the control panel to A) set 800x600, boot normally
or B) try setting your normal mode. Hope this helps even a bit.

You need to disconnect your vga cable,put in the rca cable and hit menu and reset it to lower resolution then you can change cables

I have a defender DVR system Sen. 1 just out of warrante.
The hard drive appears to have filled up and crashed.How do I reset hard drive ? Thanks in advance RAY p

The only way is to connect it to a vg computer type screen and then get in the menu if you changed the resolution on your tv you should then get in the tv menu and changeit there

several things use hdmi cabling, also change resolution (can sometimes be changed on front of direct tv receiver) or may have to go through menu to change to the different resolutions. also turn the native mode OFF! having the native mode on for directv will give sometimes give you odd pictures. also whatever resolution you choose through directv menu's make sure your tv is also set to the same resolution
