[scouse]

ok guys i've got an lg monitor in for repair model number is lg flatron w2042s, the fault, when you switch it on it just flashed up and off again so i've took it a part found 3 capacitors bulged, these were 470mf 35v so i've changed them with 470mf 50v. and also changed the rest of the capacitors as well. but the monitor is still the same, does any one have a service manual that they could up load thanks for your time.

regards

This symptom you have is '2-seconds to black'
It can be caused by a bad ccfl tube, or from a failed inverter transformer.
With the unit off, check the resistance of the secondaries of the inverter transformer, and report back the readings.
