ZV5000 ticking problem

Yet another ZV5000 on my bench with dc jack problems. Unlike most others when you wiggle or position the ac adapter you can hear a "ticking" noise coming from the dc jack area.
If the laptop will stay powered on for at least 20-30 seconds a dc jack repair will most likely fix the problem.
This ZV5000 would power on for a split second then shut off no matter what angle I held the adapter plug.
When the laptop was fully disassembled I noticed an "epoxy like" substance that some use to hold the dc jack in place and try to prevent the dc jack problem from happening again. The problem with this is you cover vital circuitry that also goes into powering a laptop.
After the jack was replaced the laptop was doing the same thing after the repair. I believe putting epoxy like substances on the motherboard is what caused the failure.
