In this video I attempt to troubleshoot the disc loading mechanism of this 5 disc changer. It has not been accepting more than one disk at a time and I suspect something is jammed. By the end a resolution and conclusion is reached.
What was the conclusion dear buddy I have same problem In Technics SC-DV290 being Panasonic Brand same DVD Changer mechanism please guide how did you resolve issued
Sadly, I never found a satisfactory solution. Between it's age, relatively cheap components, an normal wear with age, it remains touchy to this day. My son took it to college for a year and now still has it in his room in his apartment. Still works, but a little touchy. Good luck and thank you for the comment!
