Hello, yes, I have tried the steps listed in your web article. They have not solved the problem. These are my results: 1. Cold Boot TV - Sometimes, this works, but most often, it does not. Even when it works, the effects only last a few weeks. When Cold Booting does not work, I have found that removing power from the TV for several hours gets the Apps back to normal. That also is only a temporary solution. After a few weeks the problem come back. 2. Update the TV software. It's not possible because Samsung has not provided updates in more than a year. 3. Delete and re-install Apps. This does not work, and it's highly frustrating because I have to re-enter my credentials on all of the Apps. 4. Reset the Smart Hub. This works as a temporary solution, but is also frustrating because all settings are lost as well as all apps. What works best once the Apps stop working is removing the power. Unfortunately it is a temporary solution. We just had this problem on Monday and I moved the Power cord from a power strip to the wall outlet. There is only a single outlet so the TV still has to go through a splitter. That was an earlier recommendation. Let's see if that works.

Thanks. That was the problem. Dust build-up at base of the port. I needed to clean the USB-C port. I needed a very Bright light and very powerful magnifiying glass just to see it. I started with Compressed Air, but it was so compacted nothing shook loose. I then used a plastic Dental pick to loosen the dust. Then compressed air. I repeated that several times. I can still see a bit of debris but I'm nervous about getting too aggressive. The port works with the Charging cable, headphones, and Android Auto. I rarely use the USB-C port so I'm going to buy a Dust Plug from Amazon and hopefully keep this from happening again.
