Same issue here. I have had an old Samsung 32" TV for almost 8 years now and not had a single issue with it. Expecting similar stellar performance, I purchased the Samsung QLED TV (same model as above QN55Q60RAFXZA) two years ago. It suddenly shut down yesterday and has been stuck in a boot loop since. I have so far tried the usual troubleshooting steps on Samsung's website and contacted Samsung service once to no avail. Reading this post has been an eye-opener. I'm shocked to see so many people having the same issue with these "newer" QLED TVs recently. The quality of Samsung's products has definitely decreased over the years and on top of it, the customer service wasn't helpful at all. No one expects a $800-$1000 item to have a total hardware failure with 2-3 years out of warranty. Really disappointed with Samsung throughout this episode. I'm going to try again with Customer Service tomorrow, hoping to find a solution out of warranty. Will update this group on my findings.
