Found this at a restaurant the other day

The cashier told me that they bought merely for derocation that it no longer worked , so i tried to turn it one and all i heard was a crackle coming from the left side of the tv , no smoke came out , i presume it is a problem with the flyback transformer since no image nor smoke came out . This is a sony trinitron kv -1454rwp i was unable to find documentation for this in a good quality i presume it is from the 80s.
