Just for the heck of it, have you tried reinstalling the original convergence IC to see if the "humm buzz" is still there?
If it is still there, it has to be "something" that you did (in a previous post, you claim it wasn't there before you began). |

I don't think IC's involved. You say your picture is now OK. I presume you installed the correct IC's (All convergence IC's should be replaced at same time).
DO double check all plugs and connectors (matching "AB," "CF," etc.) that you had unplugged. Make sure you didn't accidentally partially unplug any others. |

| How your wires (especially speakers) are routed around/by/through areas. For example you never want to "dress" wires near high wattage resistors. |
