The green light of the TV is comes on and off but the screen stay black (standby mode). Is it a circuit board problem? If so, which board is it? Thanks
SOURCE: Have a new Sony Bravia
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...

Hello,
Unfortunately, this is a failure of the balancer board for the backlight. The unfortunate part is that the balancer is not available by itself anymore, and the whole panel must be replaced, as Sony only has the balancers attached to new panels. You can contact Sony directly to ask for assistance, and it usually helps.
Hope this helps you...

This can indicate a problem with the high voltage circuits. Since this is a new set, it should still be under warranty. DO NOT open up the unit as that will void the warranty. Return the set or request warranty service. Note the 8 blinks when you request service as that should allow them to bring the correct replacement parts.
Keep us posted.

Problem may be the power supply,check in it thoroughly and find the falty components.Remove the faulty one and replace new one.
