Dvr985 phillips

DVR WON’T RECORD GOES THRU THE MOTIONS LIKE IT IS RECORDING BUT THEN THE PICTURE FREEZES AND THE UNIT SHUTS DOWN DISPLAYING ERROR CODE DB7F56742. WHAT DOES MEAN. WHEN I RUN THE DIAGNOSTICS IT COMES UP AS O.K.

Hello and welcome.

First, I would unplug the unit for an hour.
Second, I would try to upgrade the firmware (if you do not have the latest one).

Good luck.
