Have a new Sony Bravia KDL-40W500 keeps turning off into standby mode with 8 flashes.


Hello,

There is some confusion on the model (KDL-40W500 vs. KDL-40V2500), so I will direct this toward the 40V2500.

On the KDL-40V2500, an 8X blink means the scan processer has gone bad, and the BU board needs to be replaced. If the problem is intermittent, the the AU board might be the problem, but if it all the time, bank on the BU.

A competent repair shop should be able to help you, or you can try calling Sony directly for assitance.

Hope this helps you...
