Chosen Solution
Hi all, I’m having an issue with my TV. To preface, I’m relatively tech savvy but not far enough when working with electronic components so I may need a little guidance. This TV gets used from time to time and is never moved. One day I turned it on and I got no image and some vertical white lines. Clicking the buttons on the remote gives me audio so things are happening but it’s not showing me any of it. I’ve taken off the back of the TV to look for anything obvious but I’m not even sure where to start here. I was hoping you guys could have more insight than me. I’ve included some images of what the turned on TV looks like as well as some of the elements on the back of the TV. Thanks!!
Update (10/10/2022) Worth noting. I turned the TV on with the back opened up. This unit on the power supply chip is wayy hot and making a clicking noise after letting the TV run for a bit. The TV also automatically turned off. Could be software related though (after 15m of no activity)
Kevin123432 I would consider this “The TV also automatically turned off. Could be software related though (after 15m of no activity)” as a menu setting. You mentioned that you have sound but till not tell us if ist was clear audio or just sounds. What this looks like is a bad video processor on your main board but we can not rule out the transformer on the power board. Trying to find some information about that circuitry. . It also appears that you have a loss of color. Those lines should actually be “colorful” instead of the grayscale patterns. Do check all the different video input sources and see if they all show the same pattern. Of course I can only go by the few images and the symptoms but I do not think that this is a panel error. I believe your TV uses a mainboard with the T-con circuitry integrated on it, so just one board. For now I would focus on that board. See if you find anything obviously damaged looking, like charred or missing components (check both sides since there are components on the underside
