Purple Recovery mode screen on Roku TV

Roku tv constantly shuts off , comes back on only to be stuck on purple recovery mode screen.  I follow steps to update tv but it only goes back to purple screen... the first time I did it I clicked the home button 5x’s the rewind/forward button each twice and it seem to come back on , this is the second time this has happen and now the home,rewind/fast forward button doesn’t work at all ... I’ve tried the reset button but nothing is working , I’ve only had this tv for about 2 months
