The screen was a replaced in 2018 and was working perfectly. When I asked them they told me it was one component. If that was the case why didn't they replace the MCU as well in 2018. The service manager/director had a blank stare and apologized that I was "misinformed". This is the same service center that told me that these components have a shelf life and that it is very common to have to replace the MCU every 4-6 years. I'm done with Dallas Service and headed to Plano which apparently has a much better reputation.
On a side note, while I was there another customer asked where he could get a rubber key chain. Rep said they only sold them online only and it would be 5-10 days to get one. I literally saw another service manager grab one from a drawer and hand it to another customer while I was waiting. These guys don't have a clue.
