"ShadowTek" wrote in message om... I have a 12" blue luminglas the just stop working a while back. In case you don't know what I'm refering to, (It's those cool lightning disk things that they have above the Borg recepticals/personal recharge stations in Star Trek. They react to sound or just flash visible electrical pulses to fixed settings.) the following URL has the product image and description from their website. http://www.cyi.net/result.cfm?code=q014 It was working just fine up until one day, when I tried to turn it on, it just wouldn't work at all. It was being used in a standard 110 wall receptical without a surge protecter. It sat securely on a shelf out of the way so I dont think any form of impact trama had anything to do with it. I tested the 12V output transformer (that came with it) and it was putting out 16V according to my analog multimeter. Is the 16V output a possible cause of the problem or is that acceptable? I don't really know much at all that much about electronics so I have no idea myself. I resistance tested from the power input reciever (or whatever you call it where the tranformer cord plugs in) to a bare wire where the one wire from the circuit board and all that are twisted in with the one wire that comes right out of the back of the glass and read 4 ohms. Is that normal? I have no idea what to do or how to work on circuit board stuff but I have an analog multimeter and some free time so I would like to try what I can. I got this as a christmas gift but I hear its like $100 so it would be worth it to fix. I took a picture of the circuit board as it lay disasembled on my table so maybe that will help somehow. http://www.gameroom.com/shadowtek/20...it%20Board.zip (Its a jpg file but my web server wouldn't allow me to upload it like that for some reason.) By the way, if in your response, you refer to stuff on the circuit board please call it the red thing or the yellow thing ect. since that will help the most lol. 16v is perfectly normal for a 12v transformer with no load. Electronics quite often just fail for no apparent reason, especially cheaply made stuff like the power supply in your unit. I would look carefully for cracked solder joints as I've fixed a few of those cheap Chinese made neon sculptures that had that problem, otherwise you'll need some electronic troubleshooting skills and at least a multimeter to fix it. |

I read about your problem. I have a 16" green one that is impossible to
find. I called the manufacturer today (Can You Imagine), they no longer make the size I have nor do they sell just the black box located on the back of it. I have had mine for about 3 years and it works sporatically. I believe it is in the switch that turns it on and off, I will be taking it apart tomorrow to find out. I did find a website that sells the black boxes for all sizes for $30.00,it is made by the same company that made ours. If I discover that I can not fix the switch I will be ordering a new box. Yes they run around $100, the one I have cost the person who gave it to me $175.00, so I am definately going to fix it. The website that has the boxes is: www.strattman.com. They have some AWESOME custom made stuff that I wont even dare to call them and ask for the price. Good luck, I hope you get yours working becuase they are definately very cool to look at. |

I doubt it's the switch, more likely a bad solder joint on the circuit board. |
