Vyper - printer gets stucked when heating-up

Hello,so when I try to heat-up the nozzle, in some point printer gets stuck. It do not appear on any particular temperature or temperature range. Sometimes occur on 130 deg but once when I setup to heat up to 230, the printer heated the nozzle to 260 and get stucked. When it gets blocked, heating is turning off, and only heating. Fans still works and screen is sensible for touching, however when I type the buttons it "beeps" but nothing is happening - screen freezes on the position where it was.To this post I attach picture of the main board, when marked light disappear I can hear "clicking" and then gets stucked. Also here is short clip showing this problem:https://www.dailymotion.com/video/x8jcf6nI checked all connections on the mainboard and printer head, everything looks good.
