Samsung TV Makes Clicking Sounds After Two Years of Smooth Operating

Since my Samsung brand TV has been in and out of service for front panel replacement, it has been making continuous clicking sounds (increasing from time to time) when turned on and off. Although I have called the service twice on the subject and they have heard these sounds, they claim that this is the sound of expansion. Has the TV, which has not made an expansion sound for 2 years, started to expand in 2 months? You can't even explain this to an idiot, there is a problem with the TV and you can't figure out what it is. I want you to compensate for your defect and stand behind your defective product, please fix this malfunction. Don't bother me with applying to the consumer court.
