mitsubishi vs 6047 schematic

Have a power problem on this tv. The 5A main fuse was blown. Replaced it and it never blew again. When you cut the power on to the set, the green light comes on, The high voltage relay kicks in, then it shuts off after a few seconds. Finally got the schematic for it and when the relay kicks on I have 166V coming from the main D900 rectifier. This voltage feeds the transformer and also goes through 15K resistor to a STR-M6811. I have the 166V on the top of the resistor, but on the side that goes to the input of the strm6811, it is gone. I suspect the 6811 to be
bad, but am having trouble finding a datasheet or even how this part
works. Anyone have any ideas?
