This problem usually occur in our country and this is because lots of building has poor earth system to guide against damages that may occur due to thunderstrike.
In this tv the standby light will be lit but the tv fail to come up.I tested and confirmed most of components to be good.supply to horizontal section is alright so definitely there is problem with the oscillator section because it is always the worst hit when thunderstrike occurs.The oscillating ic is stv2246c and need to be replaced.I source for another one and replace it.The tv works perfectly and the owner was happy to see his tv in action again.
