I was watching a dvd on my week-old Sony Bravia XBR-52HX909 for the past three hours when the screen suddenly went blank. The standby indicator light in red started blinking. I attempted to turn on the power using the remote but it wouldn't do so. I just disconnected the AC power cord.

37 Class BRAVIA XBR Series LCD Television

This problem u must play with the tv orignal remote.Look on the tv original remote for a buttons like Aspect Ratio,Picture Sizes,VIEW MODES,ZOOM.Just pushes one of these buttons until u have the desire screen format for u.The screen will jump every sizes,u can't get evrythings u want,have to give and take as the tv pictures exspan or contract.

The resolution is controlled by the video sources, you do not adjust it at the TV, if you feed it with video sources that is 1080i it will display 1080i.
I hope that will explain how it works.

AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

I have this amp and mine does not have the latest firmware (indicated by a green or blue dot near the serial number) and it does not pass through Audio or Video when a 3D Blu-Ray is played in my PS3 although my TV (Sony Bravia XBR-52HX909) does say "3D Video Signal Detected." No audio or video ever plays but the PS3 looks like it's playing.

I would take that puppy back to store and get exchanged out. According to lemon law. Let me know what happens. Thank you Jay.

Check the door for the lamp...over time mine distorted from the heat, and this was an error code for the door now being closed. Temporarilty I wegeded something in there to hold the switch closed, but ended up replacing the door.
