Persistent Issues with LG 50UP77006LB TV, Give me Replacement

I purchased an LG 50UP77006LB television, and initially, there were problems with the satellite connection and power cycling. The mainboard was damaged, causing the TV not to power on or off properly. The necessary repairs were done by the service, but the same issues recurred. The TV went back to the service for the second time, and the required repairs were carried out again. However, the problem persists, and currently, the TV is in the service center for the third time. I have lost confidence that my issue will be resolved. It appears to be a manufacturing defect in the device. I am requesting LG Turkey to replace my TV, as I believe it is a faulty unit.
