Same problem. Turn on tv, "Bravia" flashes on screen, then goes blank and turns off. Red standby light blinks 6 times. Tried unplugging from wall to reset, but continues to shut down. Called Sony Customer service and wasted 1 hour with them only for them to tell me call out a technician. This television is less then 3 years old, purchased in November of 2009, and is already having technical problems. Sony Customer Service said warranty expired after 1 year, so cost of repair will be borne by me. Since I spent so much money, approximately $2200 for this unit, I refuse to spend anymore cash to fix it a little more than 2 years after purchase. Seems like Sony quality and service is not what it used to be...they are building and selling cheap crap like rest of manufacturers, just charging more for the junk.
Sorry for rant, but I'm extremely disappointed at this stage. If anyone knows how to fix this 6 blink issue, I would greatly appreciate any assistance provided at this point. I'm considering possibly going out any purchasing another tv, JUST NOT A SONY THIS TIME.
