@jh120 intermittent failures are the toughest to figure out. This « a faint outline of the proper image, duplicated and shifted about 2 inches to the right » is commonly a T-con board error. A failed T-Con board can also give you a black screen with audio. [br]
I suggest you also disconnect everything from your TV (cable box, sat box, firesticks etc.) and unplug your TV. Then hold the power button down for about 1 minute. Replace one video input, preferably a local device like DVD/BR player etc. Plug your TV in and see if it works better. Firmware issues on cable and sat boxes can cause your screen to not display as well.
