LG 65UK7550 TV weird glitches and restarts
Hello,
I have problem with my LG TV - LG 65UK7550. It suddenly starts glitching weirdly as you can see in the video. Restoring to factory settings did not help. The image in the movies is fine without any problems, but user interface is glitching and sometimes unresponsive. After a while, it even restarts randomly, and from today it started to take a long time to turn on. Do you think there is a problem with the motherboard or may it be elsewhere?
Thank you very much for every answer

For a long time I could not find a compatible board on the local market. I finally found this, but the connectors have a slightly different design than connectors on my board. Will it be compatible? Thank you
