A projector I bought used for my son seems to work fine for about 40 minutes then the "lamp indicator" blinks red and the projector lamp turns off. Manual says replace bulb because it has reached its end of life. The hours indicated 611 hours which I reset with no change in operation. I replaced the bulb with a new one and the same thing happens. From what I have read (wikipedia) the life of the bulb has to do with the voltage required to drive it. It becomes higher as life goes on. I can imagine some sort of circuit to sense either voltage or current on the powersupply module and inform the processor when some limit is reached. The bulb type is ELPLP12. Does anyone have any information on this or any schematic documentation which might help me troubleshoot it. I do have experience with high voltage supplies etc. |
