    I noticed there is a DC voltage about 57V between grounds of primary and secondary circuits on the Power board (there is 57V DCV on the big left&middle heatsinks (they are connected) and small heatsink on the right (which is connected with general ground of the entire chassis or primary AC input.
    It looks like leveled half wave from the 120V AC input from the bridge rectifier.
    Is this a normal design or sign of failure ?

    Btw, did you resovle your problem Nomoresonys? Thanks
    No haven't fixed it, gave up for quite a while, just now revisiting this weird sony, lol.

          latest symptom, screen goes blank while streaming with android device, is fine til I try to increase volume with tv remote, then its like it just can't handle that little extra bit of stimuli. already left back off tv, with back on it would do same thing, with back off, tv works fine, til I try to stream and turn up or down volume, been a strange tv.

            Has anyone ever fixed one of these TV's? I've got a separate thread going about the same TV (KDL-46S4100), but this post has by far the best information (unfortunately, same result - no fix posted; I'm assuming a fix was never found).

            Wouldn't it be great to find that 1 capacitor (or whatever) that is causing all of these problems?

              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...
