Majority of the houses in the Philippines do not have grounding. The power distribution here in MM uses a split phase system - two hots and 1 neutral ground. 1 hot is 110v and the other hot is 110v giving you a total of 220v nominal. Nothing is connected to the neutral ground.

i am thinking, our TV has something like those, built in, as it's a multivolt model.
My LCD Sony Bravias are all autovolt. Still conks out after half a decade of use.

my still-functioning flat screen CRT TV is over 15 years old.
i've been lucky, i suppose.
If you have seen the "innards" of a CRT TV, some capacitors are as large as a D size battery. lol. The resistors, diodes, rectifiers are all huge! They can handle a lot of beatings and some are as old as your grandpa. Lmao!

Today, electronics are different. They are microscopic tiny and repairing them sometimes require a microscope. They are sensitive and can be damaged by static electricity and overheating. That is why a static strap is used every time you handle the circuit board.

our TV set is located beside the open window that doesn't get wet, even in strong rain. the instruction is to always put these appliances away from heat and wet.
There you go. Heat is the real enemy of all our appliances.

I've zeroed in and I found out why my Sony Bravias conked out. My 2nd floor really gets hot during summer. Both TVs are located on the 2nd floor, although I have A/C.

Being a cheap guy that I am, I don't use the A/C that often and I just open the windows for venting heat out with the help of an electric fan. The Bravias will get a dose of the summer heat of MM.

However, the Sharp Aquos is located on the ground floor in my living room where it's cool. That is why my Aquos is still alive up to this day because of the lower temperature on the ground floor.

I guess that settles the matter why your TV has lasted.

I forget that LCD/LED TVs have an operating and storage temperature. When operating, the room should never exceed 40°C and the storage temperature (TV off) should never exceed room temperature of 45°C. Kindly check manual.

Anyway, lesson learned.

Summer heat can sometimes exceed that when the metal roof transfers all the heat to your room below.

Bummer.
