Samsung Smart TV keeps clicking on and off in a cycle
Hey, so I have an issue with a Samsung tv un55ru7100fxza. It has this clicking sound and it’s in a cycle of turning off and on, you can see the startup logo for just a second before it turns off and on again. Almost every video I’ve seen so far talks about checking for bulging/ leaking capacitors but all the capacitors look fine and the solder joints on the back aren’t cracked or darkened. Next step is to take out each individual capacitor and test them which I really don’t want to do at all but I need to find the issue. I tried plugging in different boards to see if a particular board was causing it and I noticed that when I unplug the t con board the clicking stops and the tv stays on and I can manually turn it off, then I try and keep the t con board in and just unplug the 2 connectors that goes into the panel and the clicking continues, I feel like I need to replace the t con board but when I look up the symptoms of a t con board failing the tv just has fading or color distortions which I don’t have. So I’m kinda confused on why it would only click when that board is plugged in, if it was capacitor or power board issue wouldn’t the power board be clicking even if everything was unplugged? Awhile ago it’s done this but only for about 3 min then it worked fine and even for a week or two, but now it’s always doing it. I don’t know what to do since everyone I contacted wants hundreds of dollars to fix it. Is there anything else I can try?
Is this a good question?
