no if the lamp works fine for hours , could be a signal problem check signal connection and wiring

Most likely the DMD board is at fault. If the DMD board is failing it will hold the data lines in the set down which will cause it to stay on until you unplug it. The part number for the DMD board is BP96-00249A but I suggest you have a technician verify the issue and replace the board as it requires mechanical alignment after wards. Please take a moment to rate my answer. Thank you.
