Where are the fuses for mitsubishi 50111 located and what do they look like?

There is only one user serviceable fuse on the TV set on the PC board, near where the power cored enters the TV (you will need to remove the back to check this fuse (it is labeled F9D00).

The other five fuses look like small resistors and will require desoldering to replace -- I wouldn't recommend doing this without testing the fuses with a Ohmeter first, to determine if they are bad.
