Moments after turning on my Sony Bravia the green "on" light changed to a flashing red "standby" light. The # of flashes is 4 between each 2 second pause. I saw one possible reference which stated a bulb needs to be replaced. Please advise if this is a correct diagnosis. Thanks!

@capjohn not sure which model your Bravia is but a 4 blink code means either the backlight inverter board is bad or one of the backlights in the LCD panel has failed. I can also be the LD board or main logic board, check inverter board wires for arcing to ground. There is no bulb that would need to be replaced. Post some images of your boards with your question and let us know what model your TV is. Use this guide for that.
