It probably wasn't a lightning hit. I'd suspect the convergence IC's. |

Is there any way to test them or should I just replace them? The TV is in great shape I would like to fix it if all possible. Thank you! |

Open pico fuses, changed value bias resistors and heat sink transfer paste. _________________ You're over there, I'm over here. |
