How is the number of TVs watched differently,

This is a technical problem in the design and manufacture of televisions, simply put, the technology of new TV design and manufacturing includes channels that can watch more TV programs (100-300), while old TVs can generally only watch 64 channels, and they also need to be manually adjusted. Even retrofitted remotes are generally limited to 100 TV programs, and these remotes are not allowed to receive additional channels. So the old TV set can't see more TV shows.

The old one needs to be fitted with a supplementary high-frequency head. When you buy a second-hand TV, you must test it. Don't buy him if you don't have a cable. It's not his family that sells it.

When you buy a second-hand phone, it's best to try it first, many of them can't receive some units during the dry season, look at the production date of the machine, there should be no problem with the machine in the past two or three years!

Receiving Signal Problems If there are more signals, there will be more stations

It is caused by the difference in the high-frequency head inside the old and new color TVs. The high-frequency head of the old color TV did not have a supplementary channel, similar to a radio with a few bands. The new color TV is similar to a full-band radio.

The vast majority of today's CCTV systems have additional channels. Therefore, most of the old TV in the early days did not contain all the CCTV programs of today. You can buy a remote control inverter (about 60 to 90 yuan), and you can collect the whole Taiwan when you connect it.
