All the above faults are related to either X,Y or Z sustain boards. These boards look different to models to models, and manufacturer.
This is the picture of X- Sustain board of Daewoo Plasma TV.
This is an other X-Sustain Board.
Y-Sustain board the likely to be more faulty, than others. There are buffer boards to this Y-Sustain board. If Y-sustain board found faulty, it is a best practice to replace these buffer boards along with it, because, damage to Y-Sustain board might damage these boards too. There are two buffer boards. Replace these two boards along with Y-sustain. There is no way to check these boards by normal methods. If one among the board is faulty, it will effect the replaced Y-Sustain.
Like X-Sustain board, Y-Sustain also differ in size, structure to models to models.
