The TV remote receiver is out of order
It's not the remote controller. It's the TV receiver. Maybe the repairman is going to fix it
The problem of remote control transmitter is eliminated, and it is basically accepted that the receiver head is out of order, and the possibility of CPU damage is very small.Check the quality of the remote control: find a radio (or recorder), set in the middle band, and tune to the lowest position. The remote controller at the radio (best bar and radio, press the remote control button vertical), the radio will issue a "beep......" Noise. I can't hear you......" If the sound is, there is something wrong with the remote control.
Maintenance methods are as follows:The battery leakage causes serious corrosion of the positive and negative pole, and the power supply is not connected.Broke the inside of the crystal oscillator, changed just fine.Fell, causing the circuit to open the line, repair welding.Button contacts need to be wiped clean.Whether to repair, AM radio, press any button will emit a beep, beep, sound, or using a mobile phone to open the camera, and a remote controller at the mobile phone camera to look at the camera can shoot white bright flashes. If so, the remote control signal can be transmitted properly.
The TV remote doesn't work. The crystal of the remote control is usually broken or the conductive rubber doesn't work. Or a long time not used, resulting in leakage of batteries, corrosion of the battery pole, or broke the solder joints, so that it can not conduct electricity.
