Apologies if this has been answered already, I did my best to search this thread (and other Samsung threads) to find a solution that works. I've read so many posts, I feel like my eyes are going to bleed...
A little over a month ago, my UN55ES7100 started power cycling. At first it was every few minutes. I took off the back panel to check the capacitors and none were bulging. After that (perhaps coincidentally), the TV would only power cycle after about 2 minutes of being turned on and would not power cycle again no matter how long I had the TV on. It was a small enough annoyance that I could live with it. Until yesterday.
Yesterday, it started power cycling every 3-4 minutes. Again, I removed the back panel and bezel. I made sure all cables were secure and that there was no scorching on any of the boards or cables. I replaced the batteries in my remote. I turned of all Eco Mode settings. I disconnected the network cable and made sure wi-fi was off. I did a factory reset. I installed the latest firmware from USB (version 2004.0 from the Samsung site, dated June 5, 2015). After the firmware update, neither the remote control nor the control button on the back of the TV would work. I unplugged the set for a few minutes, then plugged it back in and powered it up, then the remote worked again. While recalibrating the picture, the TV would power cycle every 3-4 minutes. However, it's remained on for the last half hour or so.
Has anyone discovered a definitive solution to the power cycling issue? If it involved Samsung service (I'm out of warranty), does anyone know what kind of cost I'd be looking at?
Thank you so much in advance for any help. I'm at my wits end!
