You will need to narrow the source of the problem.
There could be a problem with the DVR box, the connecting cable, or the bulb could be burned out in your TV.
If you have a second set, I would suggest connecting the DVR box to it and see if the problem persists.
If you do not have a second set, the easiest solution is to replace the connecting cable between the TV and DVR box.
