Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.Initially and based on the described symptom and what has been done, it would be an internal hardware issue.
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
Great on the DIY!Please post back with clear pictures of the internal circuitry. Click HERE.These pictures would then serve as common references.
Yes please; post back with an update/pictures when conveniently able.
Perhaps the exploded parts diagram HERE may shed additional insight.
I realize that the above diagnosis may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
