  1. So this is my first time putting my own CTB16Kpc together and I've run into a problem. My LED doesn't light up. It did when I first finished putting everything together but I only had control over 3 channels (13, 15, and 16). I unplugged everything and re soldered a lot of the connections hoping that would fix the problem. I was also checking around with a multimeter and the board tipped over and came in contact with the support strip in my box and there were sparks. There is a tiny bit of blackening/damage on the outer connection of the resistor at station 12 but that's all I can find. So between that and the resoldering I lost my LED. I've followed these instructions http://www1.lightorama.com/PDF/Kit_Troubleshooting_Guide.pdf and have gotten to the step which reads: Check for 25 VAC by touching probes to the left side of D1 & D2, if not present or low, check voltage jumpers next to transformer, check all solder connections for transformer, fuse holders and voltage jumpers. Check that both C2 [& C3 for CTB16KV6] (big electrolytic capacitors) are properly oriented. I am getting 15.7 VAC across D1 and D2 so I am assuming that is my problem. I have checked the solder connections it says too several times and C2 & C3 are properly aligned. I'm not 100% sure what it means by voltage jumpers, I've got my voltage selection set correctly and I have checked the solder to that piece a couple times. So I don't know where to go from here. I am afraid I damaged something when it tipped over but I don't know where to start checking for that. Any advice would be greatly appreciated! Thank you!
  2. Hey guys, So a little background. I am new to the hardware aspect of LOR. I used the software to help my roommate write sequences back in college but never did much on the hard ware end besides helping set up lights. I wanted to get into it for myself so I bought the DIY planet Christmas CTB16PC box. I put it together this last weekend and went to test it this morning. I connected to the computer just fine but when I went to test my lights only channels 13,15, and 16 were working. Having no idea where to start on the hardware side I decided to try to update the firmware first, seemed like the easiest fix to me. I didn't realize how many different board options there were so I downloaded the first firmware I found for a 16 channel board not realizing I had other options. Now I realize this was actually firmware for the DC controller CMB16D. Well my board took the firmware update and i immediately lost control of it. I reset the board by turning off the power, removing the jumper from J0, plugging it back in, waiting a few seconds, unplugging and reconnecting the jumper. At this point i had a long blinking LED. It'd stay red for about 2 seconds, go off for a 1/4 of a second then come back on for 2 seconds. Repeating this continuously. So I found if I go into the hardware utility and check ignore errors on the unit id box I can find the board. It is now called Bootloader-CB16. The same LED pattern was still blinking. I downloaded what i think is the correct firmware; CTB19PC_V4.02 (I know its not the most current) and went to upload that. Since then the status box has said loading for roughly 10 minutes and the led has been solid red. Not really sure what to do from here... Realizing I'm a bit over my head and probably should have just bought an assembled board to begin with but I thought this would be fun and I 'd learn some things. Any help would be greatly appreciated! Thank you!
