all of a sudden this cd player that i paid $45 now stops playing after only 12-15 seconds. It previously worked fine. I purchased it at Walmart in August 2008. there is the initials "cb" in the upper right hand corner of the digital readout. I have tried to changing the silver buttons underneath"hold" and it won't play at all, the other switch states "on dbbs off" still nothing works. please help. These are new batteries, and it will play just stops as if it has been programmed.
