Can you see the JVC menu screens?

Thank you for checking.

Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, meaning a faulty power supply or main/control board, though there are many possible failure points. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).

This could also be the result of age related wear and tear; that type of failure wouldn’t be surprising for this brand even at this age.

There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation:
1) Unplug the power cord from the outlet

2) Wait at least 1 hour (60+ Minutes)

3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.

If this reset process does not work, it would unfortunately confirm an internal hardware failure.

This is something that would require repairs to correct; the only bit of good news here is that at 7 months it should be under the factory warrnaty and JVC would cover the cost of repairs if you take it in to a local repair shop.

I can help you with finding parts, finding a repair shop, or recommending replacement options, if desired.

My apologies for the news,

I did receive your phone call request, but I'm not seeing a contact number, can you send a number where I may reach you?
I know it may be late there so if you'd prefer to pick this up in the morning thats ok too.
