I have had this tester for about 9 months, loaned it to a friend WORKING and now he drops it off while I wasn't home and it does not function like it used to....

Any help would be greatly appreciated.

Normally when I would plug it in the wall and set the dial to

"Set Heater" the power LED would come on.

Now the only time the LED comes on is when the dial is set to

"Clean-Balance" and "Rejuvenate"

What the HELL did he do?

Probably nothing.

Open it up and you'll find a lot of pin connectors that are notorious for broken/cracked solder joints. You'll need to reflow them.
 
Thanks for the advice, found the broken wire as you indicated and its like it use to be "functioning"
