Hey, 

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.
Nothing.

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.

hi

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?

I am facing a screen/display problem with my SONY KDL32EX720. It powers ON fine, No RED LIGHT BLINKS, sound works but no picture. Display shows white vertical lines.
While cleaning the LED screen, i sprinkled little water as screen was dirty. Slight water drops might have dripped through the front screen.
What could be the problem ?
I powered OFF the TV since.
TWO days have passed & have left TV to dry but still doesnt show proper DISPLAY.
I have attached a photo of the problem.
Please advise.

They changed mine for this reason when it was still under warranty but few months later, issue reappeared.

I noticed that it only reboots when the ethernet cable is plugged so I leave it unplugged most of the time (I don't use it with internet connected services).

I believe the issue is with the software/firmware and is triggered by a signal it is receiving (not sure if its from CAT5/6 or Coax or both), gets confused on and reboots to clear the error. If you go into the service menu on the tv, the count for the Watchdog timer increases by 1 each time.

I've had this problem on my original EX720 tv, had the main board replaced by SONY - still rebooted, had the tv replaced by SONY (same model)- still rebooted, and even had the tv replaced by SONY (different model) - and it still rebooted. I've also seen the TV of a family member who has SONY model, one model year newer, and is different than either one I have had also reboot randomly.

It definitely isn't isolated to this tv model. I personally don't think its anything to be overly worried about. It's more of a inconvenience than anything, which rarely happens. And when it does happen, it's usually within the first 10 minutes of turning it on.

Do I need to update?: Your firmware may already be up to date, especially if you have a new Bravia TV model. If you're not sure, it' it's easy to check which version of firmware you have follow these instructions to check it.
Benefits and improvements:
This update enables TLS1.0 to ensure the security of internet applications, and improves the already existing SSL3.0
Restrictions: only for use with TV sold in Europe. Not all models are sold in all countries.

Sony BRAVIA KDL-40EX720, Sony BDP-S480, Pioneer VSX-521-K, LaCie mini HD connect.

Mine is a USA TV, and an update was installed a few days ago.

If the version is the same then so the changelist. Only some customization and languages differ between regions.

Sony BRAVIA KDL-40EX720, Sony BDP-S480, Pioneer VSX-521-K, LaCie mini HD connect.
