I'll be the first person to admit my knowledge of electronic component repair is lacking. Here's my problem, I hope someone might have an idea. I have two Leprecon MX 1200 rack mounted dimmers, they power the lighting in our multipurpose class room / performance space. Yesterday I loaded 12 500w Altman 65Q 6" Fresnels in the system, one MX 1200 powered 2 units, the other 10. Yesterday after the units were hung and cabled I tested the system (using a Leprecon 600 12/24 console) (I swear this isn't an advertisement) everything worked fine. When I left for the day I left the power running to the the MX 1200's but shut down the board. This morning I came into work to focus the units and the rack with 10 units on it wasn't working. Upon inspection the overtemp light is on. I tried the usual, trouble shooting ideas, I restarted the system several times, and unplugged all the units. I'm at a loss. Does anyone have an idea as to what went wrong and how I can repair it. I did some quick checking on line and to replace the MX 1200 would cost close to $3000, I have $400 available for repairs. I look forward to any help I can get. On a disparaging side note I called Leprecon tech serviced today (early afternoon) and their person was already gone for the day... is Leprecon run by bankers?
