Hello,
Recently picked up a Sony bravos KDL-46EX621 from Craigslist. It was bought in an unknown state, but a little troubleshooting resulted in a bad main board - no power and 4 blink error code with stand-by voltage correct and the power on signal being successfully sent to the main-board, but no boot up from there.
I replaced the main board and tried updating the TVs software. Let the software update run and now the set doesn't stay on. It will boot, flash the "Sony" logo, then cuts itself off and the standby light blinks 10 times. The only way to get it to do anything else is to unplug the set and plug it back in.
Any advice on this is greatly appreciated. Is it possible I purchased a bad replacement main board? Also, I can't find any information or service manuals on the KDL.
Thanks!
