Hi I have Phlips 27"tv model 27pt543s37a.The problem is HOT burned.I check hot(BU4508DX) and it was short between base collector and emmiter.Replaced for a new one.Some forums says that cause this short capasitor C2455.I replaced it as well.There was diode 6460 on the board shorted also.Replaced it.So when I turn on tv looks like High Voltage to CRT comes on but after few seconds it shorts HOT again and make inpulse noise.Checked HOT again and it was completely shorted all over again.Suspect bad flyback but not sure.Is anybody has a similar problem with this model?thanks

possibly also the line o/p transformer is duff. next time, wire a 60w bulb across c-e of the HOT without the transistor. measure the voltage, should probably be about 130-150v for this size set.
