Facing TV Problems? Ask a TV Technician.
Hello, I see you were chatting with the site's automated response system. I am Mike, the real life technician assigned to help you. Sorry to hear you are having problems.... Are you available to chat with me right now?
Tell me exactly what happens when you plug it in and press the power button?
power LED does what?
There is no easy fix for your problem. Since unplugging didn't help- I'm very sorry to say, that red light flashing means this is going to be an internal failure that requires diagnosis and parts inside the tv be replaced. If you want to DIY, let me know and I may be able to help you with that here. Previous electronics experience is required on your part. Otherwise you will need to use local repair shop. In home repairs start at $250 on this model and most shops charge just for diagnosis. So you really should compare that to prices of new 42" tv's.
I know this is bad news and very upsetting but please understand I am here to provide an honest answer. I hope you will submit a 5 star rating at the top of this page and not base the rating on the fact that your tv needs parts or services outside of our control. If for some reason you don't feel I should get 5 stars, please do not rate and just let me know and I will follow up with you here.
