Last fall my radio started acting up, vertical lines on the screen and noisy speaker. I ordered a new mainboard and installed it yesterday. It was a very easy diy job. Just make sure you identify all the plugs and wires. I took a picture before and it helped me avoid mistakes. I'm glad I did the switch and my radio works like new now. Gone the annoying noises and bars on the screen. I even did a test flight the same day. https://youtu.be/g9E9YBUzb9o
