| No they were not. I unplugged the yokes and the resistors are now reading 220ohms as they should. |

| Were the convergence yokes unplugged? If not, unplug and test the resistors again. |

| I changed the 470uf, 100uf, and 220uf caps in the hyper module. It made no difference in the picture. I am ordereing the 1uf, 2.2uf and 22uf caps. K noticed that each convergence IC has six resistors. Three 1.8ohm and three 220ohm. The 1.8ohm measure the right value but the 220ohm measure .5 ohms. Is this an indication of bad convergence IC's? I measured the resistors I'm circuit. |

| Also replace all the 22uf/16v, 2.2uf/50v, 1uf/50v caps. |

| I agree. That was my first thought. The funny thing is after the first repair the picture looked great for one day. Then I turned the set on the next day and got that. I will recheck the work. Thanks. |

Recheck your work. Easy to break/lift a trace.
 I feel the timing is just too close between the failures. |

| What specifically in the hyper module? I just replaced the 10uF caps. Maybe I should go for the 100uf caps next? Any ideas? |

Do these pics look like convergence IC issue?
