My 7 year old

My 7 year old has anger issues that when he gets upset or frustrated he flips out badly.. well tonight I went to put him to bed, and he got mad, and hit the tv screen, and now my tv is broken.. he got diagnosed with conduct disorder last year and we been trying to help him with his triggers(most of the time it’s his dad won’t see him or keep him on his schedule, witch I just got him back from the weekend with his dad, and any changes to his schedule he tends to flip out).. I want him to learn that he broke something, now he has to work to get money to buy a new one but can’t figure out what he can do to work it off.. I know he can’t control it sometimes, but sometimes I can tell he gonna flip, and have to hold him and calm him down.. can anyone give me any ideas of what he can do?
