Question about SIM2 Televison & Video

1 Answer

Projector not working

I have a Sim2 projector. I have owned it for abut 3 years. Recently when turning the unit on it would start out with a high pitched whine until warming up then the lamp would come on and the picture would be fine. Now the unit turns on for about 1 minute then shuts down without the lamp ever coming on. Do I need a new lamp? Is there something else wrong? Not sure where to turn. There does not seem to be much in the way of customer support for the Sim2 brand. I have left voice mails to the Florida "customer service" office with no return calls. Any insight would be appreciated.

I have the same problem with a HT250, red power light on back of projector will not come on. But if you leave the projector plugged in and power switch on it will light after some time and the projector works as normal. Any suggestion please email lkrause0@fuse.net

My DLP projector SIM2 DOMINO D35 is turned on and works normally BUT picture is absent on all of inputs (projector shows NO SIGNAL, green indicators is ON). Sources of signal and cables are in order. What...


It is possible that the last time this was connected there must have been an higher input applied than is recommeded so that the input PRE_AMPS were loaded to fail.
You need to check with an signal trace on the input to find if an OP-AMP has failed or the LOGIC switching IC had failed.
Need to test using a signal tester and meter.

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.

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.
