Korg Poly800/EX800 Users

I have had my EX800 since last summer and it has worked without issue. I recently moved my studio around and rewired the whole setup. When done, my EX800 would no longer power on. I thought the power input maybe was broken but upon opening it up and a visual inspection everything looks good. I've tried multiple power supplies and different outlets to no avail. I'm not sure what my next step is and I'm not really that knowledgeable about electronics to do much more. I was also wondering if there is anyone who does the moog slayer or Hawk mod that I could send the EX to and maybe get it fixed by them too for a price? I like the synth and I am willing to pay for that service. Any help is appreciated!
