Number 6 convergence issue

Toshiba 51H83. The #6 on the convergence is outside of the box and I can not get it back into the box. Can some one let me know exactly which IC (partnumber would be extremely helpful) may need to be replaced. I want to have it in hand before I open the TV up to fix it.

I have a Toshiba Rear Projection 51H83 & I think the lamp needs to be replaced. I was trying to find the lamp part number & how hard it is to replace.


On a scale of 1 to 10, 10 being the hardest: 9. This is the heart of the TV. You will need to make several adjustments to the TV once you reassemble the TV, most time consuming will be the convergence adjustments. This can take hours just to learn about. I hope this was helpful, best wishes.
