Komatsu PC12UU mini excavator

I am having problems with my mini excavator with the red light flashing and the boom not working. Tried using the over ride switch to make the boom work. As soon as I release the switch it still keeps flashing. Does anyone have any suggestions? Thanks

    I have a pc12uu. Works amazing. Might be a safety sensor telling the boom not to move.
