I had problem with my My Bravia lcd tv (40S400A model). It turned on for few second with no pics then turned off, standby green led blink 3 times. I know that blinking is an indicator to tell what when wrong, perhaps some circuit protection. It happened after I played around with usb service slot, the 5+ voltage short to ground. Yes, it was stupid.
Is there any way to reset the system ?
