I was simply trying to help you with a possible resolution before considering sending it in for repairs.
Panasonic would not repair it, they don't actually do any non warranty work.
Yes, they will tell you where to send it, but even that is not their own panasonic service center, it is a subcontractor and while it can be fixed, it is not going to be feasible to do so. You'd spend more just on shipping than the unit is worth and you could replace it with a brand new system for less than you'll spend to repair it.
Also to clarify, this is a paid support site. You clicked on a link to come here, though it may have been an ad that mentioned techs that work with panasonic equipment, this is not panasonic directly. They don't provide this type of support for out of warranty products, which is why they only would have referred you to panurgy for their subcontracted service. I have no access to or control over any billing or refund related matters.
If you'd like, I'd be happy to recommend a suitable replacement for you though.
I am an independent technician and I've spent my personal time, unpaid, in an effort to assist with the question for which you solicited my services. This site works on the honor system, and to that end, I have prioritized working with you ahead of other paying customers.
Although you’ve already paid your fee to the site, I am only compensated for my efforts when customers such as yourself leave positive feedback for my work. I apologize this is not the outcome you had hoped for, though this is really beyond either of our control. I do hope you’ll consider leaving a 5 star rating for me, rather than “shoot the messenger”, so that I may get credit for my time spent in good faith to answer your question accurately. Rating 1 or 2, or not rating at all, does not produce a refund, it only penalizes me for trying to help.
