Do you see any IRFP460 's on that board?
I realize that there are a lot of posts on the lousy Gateway Plasmas so sorry in advance for adding another.
I have now had to replace my Y-Board twice. Both times the boards blew in the summer as soon as the indoor temperature reached upper 70s with high humidity (I don't have AC). Naturally, I won't make that mistake next year.
I just replaced the Board and the TV works fine again (Go Red Sox), so hopefully I'll have the TV for the Series and for Football season.
Anyway, has anybody (1) figured out which part on the board fails?; and (2) if so, I'd be willing to pay to have someone replace that part for me.
