I have a 42" lg plamsa tv the screen went black and still had sound.. found a blown fuse on the board to the right of the power board, when i replaced the fuse,it will power up and then 5 seconds later i...


The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.
