good I have a 29-inch sony tv does not look good model but this is what is seen in tag k ... 2 ... 5, in the fault it is that the horizontal output was burned, and the transistors of source c4833, it was changed and turned on, then it generated flashes on the screen, it looked reddish and explosions in image and it became burned in this case the 4833, it was reviewed and they replaced, now it turns on but does not give video, as if the flyback did not generate the hv, there is no voltage 15v and 15v, and there is no voltage h1 and h2, but the channels sound are heard when putting antenna .. disconnect ik the resistance and nothing, where says 1000v there are 140v, in + b there are 140v, what can I do ???? thank you ... it will be that if there is a short in the tube, the flayback does not turn on so that the horizontal output manifold voltage reaches it?

if brother test continuity in the filament and if continuity is present. What I think is that there is no tension when switching on ... what will happen there? I heard over there that if it is short, it will not activate the filament voltage and other cannons, will that be true?
