Have TV Questions? Ask a TV Technician
Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
not quite sure if you're asking for electrical help or help with the tv.
But, if you unplug the tv and leave it unplugged, does the switch or other devices work properly at that point?
Okay, if you need more help anytime feel free to get back in touch.
Thank you for the update, Beverly
I'm glad to hear it is working for you again.
If you want to do a rating to credit me for my efforts in trying to help, I can send that along, or I can close out the question, at your preference.
