Hi there,

If the display is not showing anything, then it is likely that either the microprocessor or the main circuit board has failed. Spare parts will be difficult or impossible to locate given the age of this unit. You can check for any obvious faulty components on the board inside the AP, however for reliability it should be replaced.
