My soldering iron stopped heating up all of a sudden

Im sure its not a problem with the irons hardware itself since it had no problem before and it seems to start heating up for a split second before going back to 000.

Ive also never seen that dot next to the temperature which makes me think its some kind of lock?

I power cycled it completely, fiddled with the settings, checked the manual but nothing has helped.

I left it alone and it went into sleep which it said was 200°C but its completely cold, and when i shook it it dropped down to 001.

Should i just replace it?
