Look on YouTube. Lots of known issues. Also make sure you’re using an HDMI 2.0 cable and not the old hdmi1.4. The old version causes flickering, shadows and other issues.

No, don't wait. Make sure you get RCA to cover this under warranty. Don't wait for everyone with this model to have the same problem and jam up RCA with the customer service nightmare that is rampant in this industry.

Well you better be pretty handy with a soldering iron. The convergence output IC's need to be replaced. These are large plastic pack IC's with 18 or so pins that are soldered on the underside of the circuit board. These IC's are mounted to large metal heat sinks.

A little late and you've probably already solved it or are just living with it or are disgusted with it and have discarded the tv. But, in any event - here we go. The "light tunnel" bends the light toward your screen. At the beginning of that tunnel there is a plastic lens. The lens is secured with four little feet that a part of the lense. The lens is flat on the side closest to the screen. It fits on the end of the light tunnel closest to the light. The lens probably has a burnt spot. Probably the burn is caused by excess heat which is either a result of a fan failure or a one-time situation where the power went off while everything was hot and there was no cool down cycle. Another item to look at is in the light path before that lens. There is a small "window". It's actually a very thin piece of glass (about 1"X1") held in place by a horseshoe shaped clip and one screw. I think that glass has the purpose of keeping heat away from that plastic lens. If that glass is broken I think you'll have a heat "leak" and the plastic lens will continue to get worse.

unplug the television...wait 10 seconds and then plug back in....if you listen carefully after 5-10 seconds you will hear a click sound (the same sound that you hear when you turn on or off) ...once you have heard it, turn the TV on again using the remote. Do not turn on until you hear the click. If this does not work, try again but turn the TV on again before you hear the click. I dont know why it happens but it is as if the TV gets confused as to whether its supposed to be on or off. Most of the time, the solution is to turn it on after the click so I would always try that first.
