Ask an Electronics Question, Get an Answer ASAP!
Greetings and Welcome to JustAnswer.
I am Andrew your Support Technician with over 30 years of experience, it can be very frustrating when electronic devices go wrong but from my experience misconfiguration are usually the problem and they can be quickly resolved with the right advice and assistance. Please allow me a few moments to investigate, I will respond at the earliest either requesting more information or providing further information.
I have investigated the information you have provided and it sounds like you have a query relating to a JVC Television that has frozen on the loading screen. I would suggest this sounds very much like a firmware problem and would recommend we start with a power cycle, most issue as such are cured very quickly by following the steps I have attached below.
I hope the information provided today helps and if you have any questions or require any further assistance, please let me know and I will do my best to answer those!
