I haven't gotten to wade through all 60+ pages of comments but I have a question that I hope someone can help me with. 

I have a 2011 Bravia KDL-40EX720 and it is starting to not have any power.

I go to turn it on and I get no action.

There is no red light, no green light.

Then I will unplug it from the wall or surge protector for a few hours and then it starts working fine. I had a friend look at it but it wouldn't repeat the problem for him. And when I got it home afterwards it worked well for few days then today it started back up with the same problem again.

How do I fix this. It can't be overheating as it hadn't been used overnight. Do I have to unplug it from the wall/surge protector every time I stop using it ?

Is this a common problem?

I'd love for some help with this.


Also if it is a part that needs to be replaced, can someone give me model numbers for those replacement parts?  


Thank you .

raise tv stand

Does anyone know if its possible to raise the tv from the stand it sits on?
I bought a soundbar, but if I put it infront of the TV it blocks the remote sensor for the TV.

I need to raise the TV up about 3-4 inches, but I don't think this stand that comes with it does that.

My father has this model and just replaced it with a 4K Samsung. He was having issues with it changing to a green color and even replaced cables thinking that was the issue. Said it happened about 4-5 times a month and would go back to normal, but I'm wondering if this a common issue or could be the start of a larger problem. I've read some horror stories about these TVs starting to go after about 1.5 years.

So I'm wondering if I should bother to take it. I live 4.5 hours away so not sure I'd it's worth it, especially when I've heard they usually cost more to fix than they're worth.

A software update just appeared: PKG4.025AAA

Probably just a stability/internet update.

I measured the standby power consumption of my 40EX721 and is doing 25w shutdown and after 10min lowers to 12w, but remains there forever.... since specs indicate 0.3w standby consumption, what can be happening?
