Check your lamp. if it has bulges, black spots or fogging, replace it. otherwise, its your power supply/ballast.

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 i change the focus without the remote?


There ia always a ring around the lens of all optical devices. If you power on the projector and rotate this ring clock or anti clock wise then you will find that you are able to focus the device to the best of display. Else try the settings manually if there is a provision.

the number of blinks determine the problem:

Environment Over Temperature- 1 long blink / 1 short blink

Fan1 Locked- 1 long blink / 4 short blinks
Fan2 Locked- 2 long blinks / 2 short blinks
Fan3 Locked- 2 long blinks / 3 short blinks

any of these will result in lamp off and shutdown.

In the manual there is a chart which will indicate the nature of the failure depending on the number of times the red led flashes before a pause.

Most common is the projector's lamp timer has exceeded the operational lamp time limit.

While the projector's red led is flashing, press the volume up and down buttons on the projector simultaneously and hold them both in for 10 seconds.
This will reset the lamp inhibit protocol.

However if the lamp has thousands of hours of use you need to replace it before it actually fails.
