Newly renovated house, poor mobile phone signal in the living room, TV sound often automatically swi

Poor signal... It should be said that the concrete of the building is well done. At least the thickness didn't cut corners. Hehe.. Then go to the balcony and put your phone away...

Can I see the switching bar when I switch the sound automatically? It's the sound bar that pops up and down when you press the button on the remote control to increase or decrease the sound. If you can see it, it means that there is infrared interference of a similar frequency.

Find him and close it. There is usually a microwave oven nearby. Or something like a high-voltage substation.

If the voltage is unstable or there is a problem with a certain appliance, sometimes there will be inexplicable electrical problems. For example, fluorescent lamps use old-fashioned ballasts. There is a malfunction that affects the entire line of all electrical appliances.

That's all I can say. You can take off the fluorescent lamp separately, and some high-frequency electrical appliances can also be removed separately and try it out. Hope it solves the problem for you.

First of all, the above problems may be caused by the quality of the product. But it is more likely: the mobile phone information number is because there is no signal base of the telecom operator around.

The TV signal should be a TV problem or a problem with limited TV operators. The problem with fluorescent lamps should be that the voltage is unstable.

Poor cell phone reception in the living room has something to do with the structure of your house. Problems with TVs and fluorescent lamps may be caused by unstable voltage. Now some families use voltage regulators, which is very far-sighted!

It's all about electrical appliances, check whether the voltage is stable?。。
