I have lost the connectivity between my Sony TV and Sony AV System. How do I correct this?

Hi @anrosco82 You may get some responses if you let people know the full model numbers of your TV and AV System. How is everything connected and have you tried new cables and power rebooting both TV and AV System?

Thanks for your response. The TV is model number KD-49XE9005 & the AV System is Sony STR-DN1080..Hope someone can help.

So what have you tried to resolve the situation.

Always good to let people know what things you have tried to fix the problem.

In the previous post from Lightfoot you were asked if you had changed cables and tried power cycles on both the

TV and the AV processor, but you haven't said if you have or not.

Is the processor switching on, if not have you checked the fuse in the plug.

Tell us what you have done and you won't get people asking you to do things you may have already tried.

Thanks for your message. All my other devices, Freesat Box, Blueray Player, still play on the TV and through the AV System. I have tried all the recommendations from the website instructions, (more than once), but to no avail. Everything connects as normal except the TV. I do not know what do do next other than trying a factory reset. But of what though, the TV, the AV System, or both. Believe me when I say that I very appreciate your help.

Again you say you have 'tried all the recommendations from the website instructions' but not told us what these were.

Are you this coy when you go to the doctors?

With the BluRay and the Freesat box connected via the AV processor are you getting both sound and vision?

I take it the TV is connected via HDMI cable through the eARC/ ARC ports on both the TV and the AV processor.

I take it you have made sure the all cable connections to the AV processor are properly connected and also on each device connected to it.

Have you tried taking the TVs HDMI cable out and connecting it to another HDMI port on the AV processor,

for example if you know the BluRay players port is working try it in that, and then also try the BluRay in the port you use for the TV.

Do you have another TV in the house that you can connect to the processor using the same port as the current TV is connected to.

After you have exhausted cable/ device combinations you can think of and still there is no progress try a full power cycle on the processor and the TV. Switch both off and unplug. Wait a couple of minutes and then plug in and power up.

If that doesn't improve things try a factory reset on the processor.

With the BluRay and the Freesat box connected via the AV processor are you getting both sound and vision? Answer: Yes.

I take it the TV is connected via HDMI cable through the eARC/ ARC ports on both the TV and the AV processor. Answer: Yes, since I set the system up in 2019.

I take it you have made sure that all cable connections to the AV processor are properly connected and also on each device connected to it. Answer: The system has been working since I installed it 2019.

Have you tried taking the TVs HDMI cable out and connecting it to another HDMI port on the AV processor,

for example if you know the BluRay players port is working try it in that, and then also try the BluRay in the port you use for the TV. Answer: Yes. The FreeSat Box connected directly to the eARC/HDMI 4 ports works.

If you still have the problem with the TVs connection then swap the cables over so either use a new HDMI cable between the TV and the AV processor or use a cable you know is working like the BluRays cable. Answer: There is one HDMI cable connecting the eARC port on the TV to the AV Receiver which must be working because the signal from the other devices travels through it. This has been the case since 2019.

Do you have another TV in the house that you can connect to the processor using the same port as the current TV is connected to. Answer: No

If that doesn't improve things try a factory reset on the processor. Answer: My last resort. Do you mean the AV Receiver or the TV, or both?

Yes I did say factory reset the processor, but you could try both.

Sarcasm not really, you presented us with very little information just trying to get you to tell us what you have done, rather than just saying I have tried everything.

What I am understanding is that you are getting sound and vision through the processor with the Freesat box and the Bluray player, but when you are switching input to the TV only you're not getting any sound or vision, is that correct?

Have you checked the HDMI settings on the TV to make sure nothing has changed there.

If you go into the Settings on the TV, Channel & Inputs> External Inputs>

Bravia Sync Settings, is Bravia Sync control On?

Under Bravia Sync device list is the AV processor listed, if so click on Enable.

Also under External Inputs there should be External Device setup you might want to try that.

Again if you think you have exhausted all avenues then a factory reset is the last option,

it doesn't take long to set it up again, make a note of all your settings first.

Hi @anrosco82 If factory resets don’t improve things, I would try Sony Support. Make sure that you have your serial numbers and purchase invoices ready.

I have tried everything you suggested and more. There doesn't seem to be anything left to do now but a reset.
So here goes.
Thanks for your help.

Hi,

You wrote"I have tried everything you suggested and more", what is more???

How did you get on with the reset, did it help in resolving your issue?

Re: Sound System Connection Failure

I have completed the Factory Resets on both the TV and A/V Receiver.
Initially this did not make any difference. However, I started to watch a programme on iPlayer on the TV via my FreeSat box, (because the sound system worked with this).
When I reverted to watching the TV via the A/V Receiver I discovered that the sound was going to the A/V Receiver has it should.
So, what actually solved the problem I am at a loss to know.
Perhaps someone at Sony can explain?
All I have to do now is set up the TV and A/V Receiver again to try and reproduce the way I set them up initially.
I would still like an explanation as to why this happened so that I can, hopefully, avoid the same thing happening again.

Well that is very interesting, but you got the outcome you wanted, but a mystery all the same.

Do you know if your area had a power outage just before your problem materialised.

Sony aren't necessarily here, just us consumers.

Just monitor the situation over the coming days and weeks, see if anything similar happens.

Thanks for the prompt reply. Unfortunately, I spoke too soon. The system is still in a mess and not working as it should.
I think I need someone to come and look at the set up.
Can you suggest anyone/anything?

OK so you are back to square one and no sound or vision when using the TV as the input on your AV processor.

Does this still mean you are getting sound and vision from your Freesat box and your BluRay player.

If you are absolutely sure you have exhausted all avenues such as changing cables, ensuring cables are firm and secure, reviewing settings, factory resetting and anything else you can think of. Have you confirmed whether it is problem with the AV processor or the TV, have you taken the Freesat and BluRay out of the AV processor and connected them directly to the TV to try and rule out a fault with the TV and isolating the problem to the AV processor. Is the software up to date on the processor the last update was in 2022, here it is,

https://www.sony.co.uk/electronics/support/audio-components-receivers-amplifiers/str-dn1080/downloads

Are you able to take the processor to a friend or relative or neighbour to check if it works okay with their TV

and speaker system.

The very last resort would be to take it to a Sony authorised repair centre, you'll nee to search on line for the most convenient one, how much that will cost I don't know and if it does need a repair or replacement part

it could get expensive, and may not be worth it.

Unfortunately the system is not working properly and I am at a loss to know what to do next. I cannot get anyone near enough to come and have a look at it. I can't take it anywhere. I'll probably just have to work round the way it is. Thanks for trying.
