This morning I waked up, my wife was waiting for me, and rush to say "the TV at living room doesn't work"

Well, this was one of daily happening, and In most cases, it will be resolved by turning off the power or restoring it to its default settings.

However,

This time, the tuner of the television didn't work and it could not accept the input from the external input terminal.

The possibility that the computer built into the TV has broken down was coming.

I mentioned before about the engine control unit (ECU) of a car. Now, most things around us are controlled by computers.

If the cause is by software (program), it may be manageable for me, however I cannot be helped by hardware(microcomputer).

The previous TV could be used as a monitor to display external devices (such as DVDs or HDDs) even if the tuner was broken.

The reason for this happening is that all the TV interfaces are now centrally managed by the microcontroller.

If the microcontroller dies, everything connected to the television will become inoperable.

At first, I also checked the price of the TV and the repair cost, but I knew the recent TV is cheaper.

A long time ago, a 40-inch TV was over 300,000 yen, but recently I was surprised to know that it could be purchased in the 30,000 yen range.

So I think

"The buying will be cheaper"
