Toshiba TDP-P9 Lamp time reset

OK you need sensitive ears. when the unit is switched on and the ballast power supply tries to start the lamp, it generates many 1000's of volts across the lamp to ignite the mercury vapour inside, much like a fluorescent lamp.
When this happens you should hear the snapping spark noise attempting to strike the lamp.
Sometimes it's very faint on some models and quite pronounced on others. It should last for about half a second or so.
If you cant hear it then maybe the ballast circuit or fuse or the 350V DC power feed is dead.
Another way is to have sophisticated metering across the lamp connector pins to detect the presence of the bursts of high voltage.
Hope this helps.
