with a big bang, I suggest castrophic failure somewhere. Basic troubleshooting should take you to the problem. Fortunately you were not standing near the 3500 psi leak. Fluid injection into the body is incredibly nasty and many do not survive it. Did you build this system Jim or is it a MFG'd item ? There should be a mfgr name on the solonoid. I was in Aircraft Hydraulics in the Navy but thats been long time ago and I really haven't had a whole lot of experience in day to day troubleshooting since then ( besides brakes and other common vehicle and common shop stuff ). I am sure there are folks here that can help, just gotta be patient. Actually this problem may be pretty simple to find and to fix. Like the man above my post, may be as simple as an "O"ring. I have a good selection abailable here. Glad you are safe. 10-4 on the oil dry.
