Terminator 2: Judgment Day
Williams, 1991Just picked up a colorDMD for my Terminator 2. I have installed 6 colorDMD's and this is the first time I get nothing.
I did everything the same as before. I wonder am I supposed to do something different with Sigma only? I have the Sigma ROM, however the display doesn't even light up. The USB is not getting power, none of the status LED's are lit. So, I am not getting any power to the colorDMD or the colorDMD is dead?
I tried power from into J-116 and into J-117. Still nothing...
The recent production run from ColorDMD (Getaway) has a manufacturer error. if you're good with a meter, i can give you some ideas.
With the game powered on and your DMD set to DC volts, check for 3.3 volts at R2 (either side) and U2 pin 7 (these are right by the power .156" molex male connector.) I have attached a picture that shows these points (blue wire.) If there is a power problem, none of the three LEDs on the colordmd board will be "on."
If you get 3.3 volts at R2 and don't get 3.3 volts at U2 pin7, the via at R2 is most likely the problem. Randy from Colordmd says that re-soldering the R2 via often is all that is required.
I put a wire (blue wire in the picture) between these two points. I ran the wire because the colordmd worked fine for a few days, and then crapped out. I figured there was a problem that could be re-occurring, so the wire made the fix more permanent (in my eye at least.) It's probably overkill though.
Another note... the Aux and Pwr connectors are parallel connectors. Meaning you can attach the power cable to either connector. Once the colordmd is receiving proper power, the three tiny board LEDs will light up upon power on.
To add more detail... the chips on the colordmd board use 3.3 volts DC as power. Obviously wpc games don't supply that voltage. so the U1 chip takes 12 volts in at U1 pin 7, and converts it to 3.3 volts out at U1 pin 8. It goes through a choke L1 and resistor R1, then off the U2 pin 7. basically U1 is a small voltage regulator.
I got a bad one for my Getaway this week too. Their customer service was outstanding they sent me another as soon as I notified them, and included a return shipping label.
Quoted from chuckwurt:Didn't realize they did T2. Awesome.
it is a sigma display only. the color rom for T2 has not been developed/released yet.
WHY....!!!.....everyone and there Mother has a T2.....WHY will they not do it......???!!!...........Joey
IT WORKS!!!!
*colorDMD hooked up to a sound controller. The speakers and the DMD change color when the sub hits a high level. Sound controller mounted next to the sub. Simple but fun. I had a big box sitting on the glass which was what my phone was sitting on. So I could not see to play anything. So, not much animation in the clip.
Quoted from tilted81:Side note- which speaker leds are you running, those look nice
They are just the standard Speaker-LED rings. I forgot where I bought them sorry. But you have to defuse the light or it will blind you to death. I used white foam to defuse the light. I think they recently did the same thing and offer a defuse layer. If you don't want RGB controlled speakers, you can also use a pop-cap LED's from comet. Pretty much the same thing.
