Just complain and let the technician visit and asses the TV. Let him know about the flickering even though it is not noticeable now. Make out a case which might be helpful later. He would give you a service log sheet and make sure that the flickering problem is mentioned in the log sheet. In the event the panel fails these things might be helpful in replacing the panel even after the warranty period or atleast you can get a good discount on the panel if it is not replaced free. Otherwise all-together you can exchange the TV during Diwali sales with front-line Tv's like Sony, Samsung, LG...
i have lodged an online complaint via tcl website. I mentioned in the compliant That I was seeing horizontal lines in the top half of the tv display.
i have a feeling this is going to be a long drawn out process.
anyone know if they charge you for repairs/part replacement if tv is under warranty?
