Question about Sony BRAVIA KDL-40V4000E 40 in. LCD TV

1 Answer

My sony bravia television will not turn on.... when I unplug it and plug it back in, it will come on for a minute and then shut itself off, and I am not able to get it back on. It doesn't make any noise or blink any lights when I try to turn it back on, almost as if it's not getting any power. What is the problem?

We have an 80cm Sony Bravia LCD TV that continues to shut down and restart. Any ideas.


The main digital board should be suspected. There are so many other reasons too for this fault. Contact any experienced service technician.

Sony Bravia TV


If you get a blue screen at turn on and a short time later it shuts off--power supply is ok--set is shutting down as no signal detected to protect the screen.

If using a box first unplug it and wait and plug back--let box try to reboot itself.

Also as a test hook a DVD etc to a rear set of audio/video inputs and go to that input quickly when the set comes on (have DVD connected and on---see if set works that way.

No signal either a problem with the set or the signal source (box?).

My Sony Bravia will play for less than a minute and then reverts to standy. Any suggestions?


Please unplug tv from wall socket for minute or so,, replug back in and turn it On.
If tv still goes to standby itself than its standby light would blink to show an error in somewhere inside tv circuits.
Let me know how many times standby red light blinking? There would be 3 seconds long pause in blinking so count pause to pause to determine problem section.
Thanks.

Sony Bravia KDL-46V3000 turns off with blinking front light.


Sounds like the power supply may be failing. Count the beeps next time, that will give you the error code.
