Question about Televison & Video

1 Answer

I removed my SIM2 HT200 projector lamp and ordered a new one, which I have. Unfortunately, I did not properly mark which of the two projector wires is the ''positive'' wire. I suspect that although it is plugged into AC the wires seem to run through a ''diode'' that may be a DC converter. I do not have a testing gauge. One wire is longer than the other. Can you tell me if the long wire or the short wire is the positive post wire? Or do you suggest I run to radio shack and get a testing gauge?Thanks,TomChanhassen, MN

I tested the wires and discovered that the short wire is the positive wire. The DC voltage is extremely high and burned out the first "cheap" meter I used. Be careful not to tighten the positive wire on with the furnished nut to much, as it could cause ceramic to break and the bulb to lose life.

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
http://www.avsforum.com/avs-vb/showthread.php?p=17983282
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! __________________

How do you reset the lamp timer on a Sim2 Domino 60.


I would need to know the serial number of the unit.
You need to press 2 buttons on the remote then enter a five digit number to enter the service menu to reset the lamp counter.

Need to replace NEC Lamp Unit in VT75LPE. Unit is bolted to ceiling in library and unable to be detached easily. What is procedure for replacing lamp?


Hi. You are most likely going to have to remove the projector *and* the projector mounting plate in order to access the lamp door. Mark the orientation of the projector mount plate with a marker and set aside. Remove the lamp door with a proper screwdriver. The PROJECTOR MUST BE COOL TO PROCEED!! The lamp will be secured, usually with 2 screws. Loosen these screws--new screws should come with the new lamp--already held in position. Using the hinged metal handle, pull the old lamp straight up and out of the projector. ( you might have to wiggle it and work it out steadily--its a precision fit) Take your time and *don't force* it! Carefully slide the new lamp into position, taking care that the power connector on the lamp assembly is properly seated. MAKE ABSOLUTELY SURE YOU DO NOT TOUCH ANY LAMP GLASS WITH YOUR FINGERS!!! If you do get finger prints on any glass surfaces, carefully wipe them off completely with a dry, soft cloth--DO NOT USE CLEANER!! This is critical to the life of the new lamp--finger oil attracts heat and will cause the new lamp to fail pre-maturely. Re-attach the lamp door--make sure you don't over-tighten any screws on lamp or door--they need to be firmly tight but not "gorilla" tight! lol Clean any dust filters thoroughly before re-attaching the mounting plate--you'll be glad you did! After re-mounting the projector, power it up and go into the menu in order to reset the lamp timer.--Hope I helped you!---Rick

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.
