The user purchased a universal remote control from this store. After returning home, he called and said it wasn’t working properly. I initially thought that was impossible. When he mentioned changing the batteries, I suggested buying new ones. Then I asked if it might be a TV issue, and I offered to check it out if he sent the TV over. After he sent it, things got strange. He brought the remote close to the TV, but it didn’t work with the receiver. However, it worked in other areas. At one meter, it functioned normally, and even beyond one meter, it still worked. But when he moved further than two meters, it stopped responding. He tried replacing the remote, but the problem remained. Eventually, we concluded it was a TV issue.
I opened the back cover of the TV and checked the voltage of the receiving head, which read 5V. That was normal. Then I held the receiving head and pressed the remote against the bottom plate. It felt like there was a wireless signal, but something wasn’t right. I decided to look for the fault by starting with the easier solutions first—replacing the receiver. The user watched as I did so, and he asked, “Is this the problem?†I confidently said it was 100% fixed, even though I wasn’t entirely sure. I just wanted him to feel at ease.
After installing the new receiver, I held the TV while the user tested the remote. He tried pressing the buttons, and to his surprise, the remote worked up to 10 meters away. He smiled, and I laughed with relief. It turned out the original receiver had been faulty, and after replacement, everything worked perfectly.
