I guess the question would be... forgetting plugging in the usb.... what happens when you power up the set and attempt to turn it on with the "new board"? I would suspect that if you don't get some "form" of display, then you have more problems than firmware.

I guess with your experience in this post, you should be able to quickly check the voltage to see if anything has changed from the "old board" situation.

Sony EX series 5 Time red LED flash cause by shorted components on T-CON or the Panel Taps. use your DM on Diode peep ton mode black to chassis and with red line check all C which had short and follow it line.

Ok I checked the LVDS cable at the main board and it was misaligned. Re-installed it and plugged the TV in. Immediately the red standby light was on and the amber light was flashing. I inserted the thumb drive and it looked like the update was taking. Eventually the amber light turned off and the stand-by light was flashing 10 blinks.

So....what is the good news? Did I brick the turd?

Yes, 10 flash error confirmed.

Board came from a reliable supplier/refurbisher.

Plug TV in, stand-by light on solid.

Turn TV on, green light comes on, backlights flash but no picture (screen does not white flash anymore but no OSD).

Stand-by light starts blinking 10 times and repeats

Don't see a button on the remote labeled "channel" other than the channel up/down button. Am I missing something?

After pressing the buttons in the order specified the TV turns on, the Sony logo comes on screen, the TV appears to turn off and we're back to the 10-blink code.

at least this first time you see Sony logo on screen..or..?
Try again to plug it out from wall socket for 5 minutes or more then repeat this.. diagnostics mode

it may this error was registered on MB before it came to you... however we need now to clear all error code on it

The screen was facing down after re-setting the LVDS. Before entering diagnostics mode I put the TV back on the stand with the back off and this is when I saw the Sony logo.

I am letting it sit for 5min then I will re-try

This time it looks like the Sony logo tried to display but it did not, back to the 10 blink code

Re: Sony KDL-55EX620 stand-by present, no stand-by light, AC_OFF_DET @.47V

do it again.. by plug it out from wall socket. this time reset all cable socket on the Set. check the LVDS side which was not correct seating. if any of silver pin was broken or moved to side or get short

Re: Sony KDL-55EX620 stand-by present, no stand-by light, AC_OFF_DET @.47V

after this time when you do it, don't inter diagnostic mode... inter from STB state to service menu... with RC Display , 5, volume up , power
