I have an Element tv that started getting these horizontal black lines across the right side it started with one then slowly there were more and more. Now if you leave it on for about a minute a large portion of the screen begins to flash black and white, then a few more minutes later it takes over more of the screen until the whole thing is flashing (it does it in sets of three takes a half second pause and does it again it a very quick flashing and the clicking goes at the same time as the flashing) unit powers on just fine i dont think it is the capacitors, i looked in it and they all seem fine. Also dont think it is the input because it does this with or without anything plugged into it. i feel like it might be something with the screen ( how expensive is it/ complicated to replace that part of the tv? ) but i dont see how that would cause the chirping. anyway thanks!
Nina W. the chirping can be caused by a couple of coils. Try to isolate where you hear the chirping coming from. Post some pictures of your boards etc. and mark the area where you hear the noise. Horizontal lines are most commonly caused by a bad display. The LCD screen has a few boards directly connected to it and those boards are not replaceable. You’d need a new screen if those are the issue. Adding images to an existing question
