Question about Sony BRAVIA KDL-40V3000 Television

Cannot get the TV to Power On

I just took my new Bravia out of the box, and when trying to turn it on for the first time it will not come on. The green power light comes on for about 1 second and then the red standby light flashes repeatedly. I tried plugging and replugging but that does not help. Any thoughts?

Hello,my Sony Bravia HD TV (LED & LCD) we suspect that it was struck by lightning,but my other appliances connected on the same power cord as my tv are working fine,so i'm confused..

The power surge from lightening can come in thru the antenna or cable box. Also just the proximity of lightening can damage one item and not another. An ic chip can be destroyed from the charge in the air.Likely took out power and main brd both.

Sony Bravia brand new ran a couple of time then won't turn on. Green light comes on when plugged in and flickers when remote buttons are pressed but goes back to green and no video or sound No flashing red...

If this is a new TV then don't even bother trying to fix it, get it back to the store and get them to fix or replace it. It should be under warranty and there is no way it should have any problems out of the box. The other side of that is if you try to fix it or have someone fix it they can cancel your warranty.
There should be no problem with the return and then you will have a new properly working TV instead of a repaired one that you won't really trust that much.
The symptoms would indicate a problem with the power section and perhaps other issues. Not cheap to fix and not acceptable in a new tv.

TV does not turn on

Ensure that the TV plug connected firmly to the mains power supply, if nothing happens,
It is require of you to open the cover of the TV to check for blown fuses, if found, do replace with a new one of the same current rating.
if otherwise your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power suppply board just have dead leakages gases capacitors.These capacitors alway bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get ur tv power stable,and work again.Or tries websites like, to buy a whole rerfurbish power supply board for the replacement.

Sony bravia kdl-52w3000, turn tv on, no picture or

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Closed Caption on Sony Bravia

Try a master reset on the TV. With the TV powered on, prss and hold down the up button on the remote (there are 4 buttons grouped together for up down left and right) and while holding down the up button, press the power button on the TV. The unit should power off and then turn back on and ask you to select a language. Let me know if this helps and be sure to rate this solution. Thanks!

Try resetting the TV by holding down the "up" button on the remote (with the TV powered on) and then, while you hold down the up button on the remote, hit the power button on the TV. This should do a "factory reset" which will wipe all settings in the TV. There is no reason why the TV should not "remember the last input it was on when it was ;last turned off. Also be sure that the TV is not plugged into a switched AC outlet, like the outlet on the back of the cable bix. The TV should be plugged into an output that receives power at all times.

Sony Bravia LCD TV is tripping the fuse in the house

These things draw a huge surge current when turned on. What size fuse are you blowing? These things can surge 10-12 amps on turn-on. What about a fuse with a reset button. They will take alittle more surge before they go. Don't matter about the insignia working before because the cheaper sets tend to stay powered up more when off....thus not surging on from a dead start. Could you try a different plug on a different circuit/fuse? and see if that makes a difference. If you have a 15 amp fuse, then your pretty close with other stuff plugged in. What size is your service? Do you still have an original 60 amp box with screw in fuses? Is it an old house?
