    Thanks for the reply! I'm a complete novice when it comes to fuses. I searched for PICOII and there are so many. Does it make a difference which one I choose (see link below on the search)? Those are the 3 amp fuses. Is one better than the other?

    Also does anybody have any comments on where to get the the 5A 24V micro fuse (breadcrumb) that is on the BU board. Would digikey have that under some other search parameters? Or can I just use another PICOII fuse?

        I have a problem with the F100 on tcon board, blown. My F1422 is ok as I have 12V to one side of the tcon fuse.
        Also had bent pin on tcon connector causing two pins to short together, probably due to not pulling the connector straight when removing.
        Anyone ever had fuse on tcon blow?

          I would love to find a tcon schematic, but doubt I will find one.
          Anyone know where I can get one? I have the manual with other boards.

              Re: Sony Bravia no Picture

              Hello, gents im having the same problem with my KDL-55EX713
              Screen started going bad with lines on the left hand side only.
              Then gradually went to the full screen. Then went washed out, and then completely black now.
              This was over about 2 hour period.

              Now if i turn it on, just a black screen.

              Could this be the t-con ? I visually looked at the power supply board and all the cap's look to be good. When i turn power on there is a click

              Any suggestions?
              Where can i find schematics for my model?
              Thanks guys!!

                      @djpat1974, you should start a new thread since your TV is not the same model as in this thread.

                        there is a VERY EXTREMELY SUPER MINI TINY fuse on the signal board that popped when the t-con went bad. I am thinking smaller than SMD0603
                        you must replace this fuse. This fuse supplies the 12V to the T-con board, and if popped, you will get no 12V to the panel.

                        These boards are riddled with tiny fuses. id say theres maybe 5 to 10 of them in various circuits. there is one popped, and i think its near the center of the board on the back side.
                        I have this tv with the same symptoms. When you say the signal board are you referring to main board with the inputs on it?
