Lucky. But Sony will never extend warranty for 7 yes.I had my LG TV's warranty extended for 7 years. A 2-3 year warranty costs some 10k. That may be a good option.
My Sanyo that is over 8 years old is still working well with minor repairs.
It is a question of how you use the TV and how your financial vs upgrade lusts balance out.
Sony makes excellent mirrorless cameras and ANC headphones.Sony has a habit of creating products that die in 2-3 years. They have really gone out of the way to optimise technology to perfect that.
Today, Sony does not hold much technical lead in any area. An LG, Samsung or others have similar technologies, are much cheaper, and last longer.
I stopped using Sony after the death of the Walkman.
I don't have a single Sony product. The TVs are Sharp, LG and TCL. The fridge and microwave are Sharp, communication equipment are all Panasonic. LG offers extended warranty. I do hope TCL does the same. For Sharp I have a genuine service Engineer who does a good job. That is all I need.
