I represent ASA Electronics, the producer of the JENSEN brand of televisions, stereos, and speakers, Voyager brand of observation monitors and cameras and the Advent brand of appliances. At ASA, we strive to provide excellent customer service and product satisfaction and would like to offer some assistance in this matter.
Please try resetting the DVD deck mechanism and the main unit. First, press the reset button, which is located just above the "DOLBY DIGITAL" logo on the lower left side of the unit. Use a paper clip or ball point pen to gently press that for about 1 second. Next, press and hold the EJECT button for 3-4 seconds. You should hear the DVD deck mechanism make noise as it resets. See if these steps get your unit working again. When you re-test, make sure you are using original discs in good condition.
If you need further assistance, feel free to call. You can reach us on our toll free technical support line at (877) 845-8750. We are available M-F 8:00 AM till 6:00 PM EDT.
Please let me know if you need any further assistance.
