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
Update (10/27/2021) 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 (photo of my board is on the left site, everything else on the board seems to be the same)
Andrej Pracovný účet that is one interesting error. The way I see it and can judge by your video, this is either a main board error or a LCD panel error (unlikely). Schematics for your main board are not to be found so you would need to replace it to see if that fixes it. If it does not you will have to dig deeper into the panel driver and see if there is anything that has failed. Schematics for that board are not to be had so this could lead to having to replace the screen (again, unlikely but there is always the chance). Go with the main board for now and let us know what you find.
