im not sure if they were blew when origanal blown board was in the set as i never checked them till today.
i replaced the blown bank of 4 470 resistors and 1 diode with good resistors and diode.
tested tv and noticed it blew all the new ones i replaced again?
so not sure if it is the new tuner or maybe just faulty panel as dont think any other panel would cause just 4 resistors and diode on right side of bottom buffer to blow again. |

the resistors and diode are failing due to the panel drive ics being sc, as these are part of the ribbon connectors the only course of action is to replace the pdp, not viable unless you can get a second hand working panel from somewhere as the cost of a new pdp is usually higher than a complete set. |

Or try the original part number digital main board for the panel. |

forgive me if im wrong but would the digital mainboard cause the lower buffer cof resistors to burn out ? |

If you're over driving the panel because of the size difference I'd say yes. |
