@xboxmods2977:
Is a tsop replacement a sure way of fixing Christmas Lights?

Glad you brought that up. I wasn't even thinking about it.
If I had to guess, I would say that about 10% of naturally occurring FRAGS (meaning no direct user error) can be fixed with a TSOP flash. Maybe even less.
@loady: You may be looking at a bigger problem, because, unless you have killed the TSOP yourself attempting to flash it, the bios/onboard TSOP itself may not be the cause for the FRAG.
That said, you really can't make things worse by flashing the TSOP in attempt to fix the problem, and in fact, a TSOP flash would be the first thing I would try, being the easiest approach in the potentially long process of recovering that xbox.
Good luck.
