My kp-57ws520 standby light blinks 9 times tv does not come on any more it did for a short period of time

I had a similar problem with a sony 60" lcd hdtv. The normal power on light was green. When I had an issue the led would flash about 8 or 9 times. Can't remember exactly. It turned out to be a troubleshooting code. When I researched it, turned out to be the high powered lamp that lights the lcd screen was shot. When this happens you get no picture or sound. It's not a terribly difficult job to replace it yourself. I found a replacement bulb on line by my model number along with instructions on how to replace. You probably get about 4 or 5 years out of a bulb depending on usage. Hope this helps.
