    Sony KDL-40U2000 problems to start

    I will recieve two Sony KDL-40U2000 with the same problem, they refuse to start up. One of them can occasional start up once in a while but not often.
    I begin to check with you guys what to expect. Bad caps in PSU?

    Said to flash standby led 4 times...

      I wouldn't suspect bad caps - not typical of Sonys. I found this online: http://www.fixya.com/support/t447566...ashing_4_times

          Thanks capkid!
          The service manuals displays 4 blinks as "panel failure". Guess they put everything inverter, T-con and panel itself as being "panel" parts.
          Recieved the sets today, and checked the fuse on T-con = OK.
          So, will check the inverter.

              Checked the inverter and a small SMD fuse 0.5A was blown. Jumping this dude with a slightly bigger fuse, set starts up.
              So, this will probably not lead to any bigger repairs for now.

                  Sony KDL-46HX850 Can't upgrade/update firmware
                  by dkneyle
                  Diagnosed this TV as having a failed main board which I've replaced with one from a KDL 55HX850. They are (supposedly) the same board.

                  Being 'Smart TV' it requires a firmware reboot when you swap out boards such as T-Con or main board. It starts with a black screen and flashing yellow and green LEDS, indicating it needs that firmware boot. The procedure described all over the web is to put the software into the root directory of a FAT32 formatted USB drive and it should load that up once plugged into USB1 port. But not for me. I can see the LED on the USB chip flash for about...
