In early 2017, I purchased a 55", 4K, Westinghouse TV, model# wd55ub4530 . Worked great for a few months. Suddenly the picture would go out, and started cycling(about 5 seconds each) through solid color screens. Red, green, blue, white, black. Sound keeps going as usual. It won't stop unless I turn TV off, and then it is seemingly random when it may get normal again. At first it was rare, then started to happen more often than not. Currently, it has been stuck in this cycle for about a week. Westinghouse won't reply to any messages. Has anyone heard of this, or know how to fix it?
Thank you.
Thank you.
