Question about Televison & Video
A while back, I had posed the following problem: That my Mitsubishi WD-62627 DLP projection TV goes black & white after it's warmed up. The solution offered was that there was most likely a problem with ICs. What I've found since then is that if the back of the set is removed and a small floor-type fan is placed against the chassis blowing a steady stream of air, that the problem doesn't occur. I have just received a Mitsubishi service manual for this set but it's sparse on troubleshooting. Sounds like a component that's getting too warm, such as a capacitor, transistor, IC, etc. Based on what I've described, does anyone know which PCB's and/or components I should be looking at? Could it be a problem with the light engine itself?
The first one sounds like one of two bad boards. If you get color here always(component input (Y Pr Pb) then it's the terminal 2 PCB, and if not it could be FMT board. Either way you would need further checks to make sure. For the other set i would need email for instructions, because of broad range of problems!

Not off hand, but you can call them and ask for the part number and order it at the same time
Let me know if you need any other help

SOURCE: green convergence, bad IC?
C8011 could definately cause the problem you are indicating as one side of that capacitor is tied to the postive feed for Red horizontal in IC8001 ( STK392-560) and the other is tied to the Green vertical return . I would replace that along with the IC as the IC is sure to be weakend if that capacitor has shorted. Let me know if you need further assistance.
