I bought a brand new Samsung 75" TV. The remote control stopped working after two weeks. I called Samsung warranty service. I spent close to five hours on the phone answering questions and working on the TV as per their telephone instructions. They finally said that something was wrong with the TV, and we would send a repairman after two weeks. However, it would be best if you stayed home all day on the day of the repairman's arrival because we can not give a fixed time on the repair day. I decided to return the TV to COSTCO from where I bought. Worst service I have encountered.
