I had a look in the service manual/schematics, and it doesn't include details of the individual parts on the LCD PCB, as it is supplied by a different company, and referenced in the MPC documentation as the LCD being a whole/single part.
Hopefully someone else can help you out.
I can't even read what the markings are on the part itself, they are too small for me to see with my poor eyesight, might be able to bring home a magnifying glass from work tomorrow and have a close look.
Thanks, the only thing that can be seen right now because the transistor is cooked is an R in the top of the body and in the pbc section = cbe for the pins and a TR
There is a dot to the left of B, at the bottom, a dot between the B and R, in the middle, and two dots to the right of the R, at the top, don't know what the dots mean.
