put finger to keyboard and composed:

Toshiba 42HP66 (made by LG?) Has sound but no picture at all. Found
FS-2, a 4 amp "T" fuse blown on the "Y Sustain" board. If fuse is
replaced set won't power at all. Board too expensive to replace.
Anyone know of any common failure that might cause this?

According to the following LG guide, the common faults are open fuses,
blown FETs, and bad IPMs (Intelligent Power Module):
