You guys wrere right, the initial problem was a coolant leak from the
red projector lamp. The proceedure for repair. I ordered a service
manual from www.servicemanuals.net. Then I rmoved the main board
from the VS-50703. I used a VDM to trace the board. Found that
several components were setting in fluid. That whole section of the
board confirmed to be a short. I removed a large heatsink and 12 or
so components. I cleaned the board with lectra clean. You can buy
this at home depot, comes in a spray can. After I cleaned the board I
measured the board for any electrical contact where the fluid was.
Made sure there was none! I then installed the parts back on the
board. I replaced any part that was corroded or damaged with new
parts. Then I made a tray that would collect any fluid that drips
from the projector lamps in the future. Total cost of materials about
$70.00. Mitsubishi charged me $31.00 for 2 coils however I requested
2nd day shipping. The 2 coils were $16.34 from mit.
