One of the most common issues is a failure to power on. You press the power button, and…nothing. No picture, no sound, no indication that the TV is even trying. This could be a problem with the power supply, but it could also be the placa principal itself, not receiving or distributing power correctly. Then you have picture problems. These can manifest in many ways: a completely blank screen, distorted images, flickering, or lines across the screen. These issues can often be traced back to the placa principal's video processing capabilities, or even issues with the connection to the T-Con board (which handles image timing). Next up are sound issues. If you're getting no sound, distorted sound, or intermittent sound, the placa principal's audio processing components might be at fault. This could range from bad capacitors to issues with the audio codec.

Another very common problem is smart TV issues. If your TV is freezing, slow, or the apps aren't working right, the placa principal could be struggling to handle the smart features. This is often related to the processing power or memory on the board. A lack of response from the remote control is another sign. The placa principal handles the signals from your remote. If the TV isn't responding, then there might be a problem with the remote receiver on the board. Then, there's connectivity issues. If you're having trouble connecting to Wi-Fi, the placa principal's network components could be faulty. Or if you're not getting any signal from your HDMI ports, it could be a hardware problem on the board. Each of these symptoms points towards a problem with the ILGI 50UN8000PSD placa principal, but thankfully, there are things you can do to figure out exactly what's going on.

Over time, heat, voltage fluctuations, and general wear and tear can all contribute to issues. Capacitors can dry out, and solder joints can crack.
