Yamaha DTXpress/DTXplorer/DTXtreme

thanks for your imput keith. the problem has developed just recently 
so I thought it was my player. I'll try toning it down but I'm trying 
to integrate an accoustic set with the e set and balance it 
altogether. no easy task!!!  I'm going to try and contact the repair 
shop and see what they replaced.  I think the laser is just getting 
old and they don't want to replace it 

            again thanks for your time  melon
