flashing red light.. turn on goes green but screen flickers
"Abbie pearl Akers something like that is usually caused by either a bad main board or a failed T-con board. You will have to remove the back from your TV and take a good look at the boards. You will need a multimeter for some basic testing of that. Once you remove the back, post some good pictures of all the boards and the wiring between them. That will allow us to see what you see. It will also allow us to point test points etc., out to you. It is not really complicated and if you are game we can try to get this TV back in working order.
