Hitachi 53FDX01B, has sound, no picture	Can't Post

Hey gang, I have a Hitachi 53FDX01B, that has sound when I turn it on, I could actually change channels and listen to it, but has no picture at all, the projection tubes do not come on at all, the million dollar question can it be the convergence problem or a resistor, fuse problem. thank you for the help Smile

I'm saying that the microprocessor tells the "TV in one chip" IC to put out a horizontal drive signal which is fed to the horizontal driver transistor, which is fed to the horizontal output transistor, which then feeds the horizontal output transformer (flyback), which then puts high voltage into a "Splitter" and is then directed to each CRT.
