Dear all,
 
A few weeks ago I had posted a message about our problem in hoping to get some tips from the community. The amount of help I got was overwhelming and I appreciate all that time you had spent on it. 
 
The good news is the problem had been solved. It turned out, like some of you suggested, the power supply to the sampler was about to go. It works fine after the replacement. 
 
The replacement was done by Mandell  in their company (not the greatest experience, but purpose was served.) and costed us Can. $ 754.
 
Thanks to you all for the great help and I appreciate it.
