This is the trouble of using board mounted power jacks as they are never made for long term abuse. The use of an epoxy and then some resistor lead patching will be the solution and of course not to twist and torque that power plug. This has happened for 2 decades with Sony Walkmans and any portable equipment.
Thanks for your reply but i replaced the power jack. One of the solder pads lifted off the board when i did this so i was looking for a schematic to see if i could run a jumper. Instead i exposed a copper trace on the board and soldered it in but the unit still doesnt work. Is there any place i can find a 414mkii schematic or can purchase one so i can do some real troubleshooting?
