gel image background

Our 373 stretch has developed a background problem on the gel image On 
the last two gels run 
we're seeing a significant light blue streaking and a yellow grainy 
background on the gel image.  
The plate check is a flat line.

    Fortunately the data can be analysed and looks clean.  But it's very 
difficult to check the 
tracking as the tracking lines are so similar in color to
this streaking.  

    The machine had its annual maintainence two days before the problem 
developed.  We had two 
clean gels before the last two with the streaking.

    Has anyone had this problem and found a fix?  Changing the gel 
contrast helps alittle.
