Recently my H56 suddenly decided that it would power itself off within 10 or 20 seconds of starting up (every time), so after trying in vain to work out what was wrong with it I ordered a new lamp. The time from startup to power-off was decreasing each time, so there was no opportunity to check the lamp hours. The new lamp fixes the problem (which strongly suggests that it was indeed a lamp problem !), but now I can see that the lamp hours are actually at 1152. Two questions: 1. How do I reset the lamp hours ? I assume that this is done via the service menu, but a Google search reveals nothing that I can find about how to get there. On the H30 there is a sequence of buttons on the PJ itself, but that sequence doesn't work on the H56. I've seen this question asked before, but never answered... 2. The 'lamp' LED is green when the lamp is running. Since I can't find the user manual I don't know whether this is normal or a fault condition - in another thread it was suggested that this indicated a fan failure. Can anyone confirm what the 'normal' state of the 'lamp' LED is on an H56 ?
