Sahara DP3601 video projector,2006
Bright orange, 2 of these , minus the security necessary top control panel
for each, not found a pic of them yet. 15 way connector for a panel , that when removed, disables the projector. Any chance of hacking them, there is a IR receiver lens but that presumably would be disabled with an absent top panel? presumably most of those 15 ways will be a diode matrix for control buttons and anunciator LEDs. Little info found on these projectors but Google images suggests Delta and similar model numbers maybe a related badge name. Googling the lamp numbers has not shown up any model Xref One lamp is physically blown, the electrode , external to the axial quartz glass stem but in the central bright quasi-focused beam area is broken, not actually where it emerges from the stem. Surrounding the break , and also the supposedly working one, in that area, is a neat looking aggregation of spikey white crystals around the conductor. I've not found an image of a new bulb yet , but could there have been a piece of silicone there that has degraded to silica crystals (asbestos-like)? perhaps creating a hotspot for the lamp current and then failure, actual and potential, at that point? Any pointers to a procedure for hacking the control-defeat function of these top panels? |
