Have TV Questions? Ask a TV Technician
Welcome. I am Mike, an experienced field technician. We are now connected together on this convenient website where I am able to help you.
Seems like you have done quite a bit of testing and resets. Unfortunately there is no magic fix, at this point the Main board inside the tv needs to be replaced which costs about $150 (labor not included). If you are handy with tools and tiny wiring harness connectors, then reply back and I will be happy to help you with a DIY repair. Otherwise a repair shop will be needed.
I do understand that finding out your tv needs expensive repairs is not pleasant. I am sorry for the bad news.
Let me know how else I can help and before you go please take a moment to submit at least a 3 star rating at the top of this page. Then if you still need help you can reply back and I will be happy to assist you further.
Hello, just checking back in to see if you still need help, or perhaps you would like to acknowledge that my time and input has been helpful?
