sorry for the delay in the response. Been out of town for a while.
I ordered the chip because I do not know what else to do. This makes absolutely no sense. I went ahead and replaced the original transistors again with new OnSemi versions and the problem still did not go away. I am going to be installing the new chip today to see what that does, but I have no expectation it will make a hill of beans difference. How can you replace every single part with brand new pieces and get the exact same result. There should have been SOME improvement....and there is nothing. I have traced this board 10 ways from Sunday on my scope to find a 'culprit' component; if one exists, I am not finding it.
I am not familiar with the BFV cap method. Can you give me some guidance on this?
