Narrative:

During the acton one arrival to dfw I experienced radio failure. I had not received final clearance to dfw and was unable to determine what the problem was. Due to airliner traffic I elected to make a left turn from 040 degree heading to 250 degree heading and proceed west from the dfw VOR hoping to get in a clear area I climbed to 6000' in order to obtain visibility contact above some clouds and began working on the radios and associated equipment to try and locate the problem. I found that when I had placed my chart book on my lap to set up the approach I had unplugged the radios. I immediately corrected the problem, called dfw approach and was given a right turn to 060 degree heading and a descent to 4000'. I was then radar vectored for an ILS to runway 13R at dfw. No further problems were encountered.
