SOURCE: CONNECT CABLE TO MY PROJECTOR
Depending on the specific model of your Mitsubishi DLP, you can have either S video, RCA, VGA or a few other choices of INput connection.
Depending on your cable provider and hookup, you can either have a plain cable with F connector or a cable box normally with RCA connectors and a remote control.
If you have a simple cable connection that attaches direct to a TV (no remote, no box), you would need a TV Tuner to be able to receive the different channels whose output would be a composite video signal into the yellow RCA jack. You would need an RCA to RCA cable to in turn connect it to your Yellow RCA Video INput of the projector. In the absence of a tuner, an old VCR with such a feature would also serve the purpose. In some instances either units may also have an S video connection.
If you have a cable box with with remote, then there is no need for a tuner or VCR since its output would already match the projector's input.
Either way you would need a separate audio amplifier/speaker for the sound.
Hope this be of some help/idea. Pls post back how things turns up or should you need additional information.
Good luck and kind regards.

Use the remote to go into the menu and change the screen position. There are 4 to choose from, flip left, flip right, flip upside down left, flip upside down right. It may be tricky to navigae the menu backward though.

SOURCE: HD 70 DLP Projector problem
Hi, My name is Doug Stanko.
I had the same issue and fixed the problem.
All you have to do is take a few screws out..... and blow out the inside VERY well with pressurized air. I have a compressor... and I set the regulator to 50 psi. But the KEY IS TO have the covers off so you can get between the circuit cards and blow them out. They were incredibly dusty. Even after I blew through the side vents.
I agree with all of you that say it is overheating. You are right. There was so much dust on the fan blades them selves... I'm suprised they were still spinning at all.
And like most of you... first I bought the $300 dollar bulb... put it in and 10 minutes later it was doing the same thing flashing through the colors. So trust me.
There are 4 screws on the back. Take these out.
There are 2 small nuts on the back around the VGA input. Take these out.
There are about 5 screws on the underside (think one was on the bulb changeout portion). These have long copper colored bars that go all the way from top to bottom.
All these have to be removed. Then you can take it apart. AND I PROMISE YOU WILL SEE TONS OF DUST ALL OVER.
Make sure you blow out the parts between the circiut boards AND the fan unit.
Put it back together... and remember to make sure that little latch on the bulb change cover makes the click sound ( it is a switch that must close or the unit will not power back up )..... and it will work great again.
No need for a huge fan next to it. Although I will admit that is an excellent idea.
I did this 3 weeks ago and have been watching it with no issues.
If you do not feel comfortable taking the screws out yourself..... I would take it to your local TV repair store and just ask them to take the covers off and blow out all the dust... and give it back to you. No troubleshooting... no repairs... no replacements... just blow it out.
I was an electronic technician in the US Navy for 10 years... Now I work at a nuclear power plant in Illinois. BUT I PROMISE with a good phillips head screw driver and a small crescent wrench you can do this yourself.
Good luck and you are welcome. I know how frustrating this issue is. But this is the fix.
