Folks, Today during a software update we had a power outage, since then, my TV just shows the initial Sony logo and it turns off itself. I was wondering if there is any way to go back to the last functional software. Anyone has any idea on how to fix it ? Request Sony service is not an option, since I live on Brazil and here this TV is not available yet, so no support. Ship to US is very expensive. Thanks in Advance for any help!
