How to reset lamp hours on Sim 2 Domino 18


I am not familiar with your brand in particular but they are all pretty much the same. In the menu under settings you should be able to scroll to lamp settings. Under that category or something like that will be where you can reset the hours.

We have a replacement bulb and I don't have a trap door to remove the old and install the new.


WARNING! Sim2 does does not recommend that you change the lamp, they recommend that you contact a local dealer for service. PROCEED WITH CAUTION!
If you still wish to proceed. This instruction is available at avsforum

There are 2 recessed screws on the bottom near the front of the projector (really deep cavities). There are 2 on the backside of the unit. Remove all those and the top cover comes off. Inside you will see a fan held on by 3 screws (you will know it because there are 4 holes, but only 3 screws...that is normal). Remove those and take that fan module off. The lamp is then accessible.

Good luck! __________________

SP4805 Fan Issue


the fans in these models do not have a speed sensor wire to let the main board know to turn off the lamp to not risk overheating. so if the fan goes, the lamp remains on. however, if the lamp exploded, check the vents for dust. there is a temp sensor that will shut down the projector if it gets too hot. if the vents are clogged, blow the dust out of the projector with canned air. the dust keeps in the heat that the projector is trying to expell. easiest way to repair the fan w/o buying a part: splice the fan wires together. they can share voltage. if the 80mm fan does not work at all after that, replace the fan (pn: 526-0192-xx).

Hi there

I checked the manual of your Sim2 , but they don't even mention the lamp in there.

You already have the front cover off , check if you can see any small screw around the lamp housing. They normally attach the lamp's housing with tiny screws to the rest of the unit.
