There is clearly a short -circuit so there is a failed board in the set could be powerboard could be one of the scan boards,checks with a meter will be needed to verify which,costs of board(s) vary however $100 is considered near the mark if you do this work yourself, I am sorry this is not something easier, if you need more help with it let me know.
With plasma's checks are needed with a meter,you have a shorted board but which one will depend on checks
