    I have a Magnovox 52" tv model 6p54230 w102. I have no picture but I do have sound...I am thinking it is the picture tube but not sure. Any Ideas?:confused:

    I doubt it would be the picture tube itself.I don't know that TV specificaly, but the GENERAL TV circuit can be applied also. I would be more suspicious of the High voltage circuit or the Flyback transformer or (LOPT). Most times there is a High Output Transistor that controls the high end voltage, and sometimes a regulator as well. Check these items too. But if the "HoT" has blown, then something caused it to blow such as a shorted Flyback transformer.
