Panasonic TX-L55WT50B TV. Problem with Sony Home Cinema Unit. Sound but No Picture.

[JSoapy]

I have a Panasonic TX-L55WT50B TV and a Sony BDV-E880 Home Cinema Unit. They have been working fine for over 10 years.

They were working the last time I used it to watch a DVD about a month ago. But yesterday playing a DVD results in sound but no picture. It’s connected to the HDMI 2 (ARC) Port on the TV.

I have tried so far:-

• Disconnecting/Reconnecting the HDMI Lead.
• Different HDMI Lead.
• Disconnecting both Power Leads for an hour.
• Using different DVD’s (Blu-Ray and Standard)
• Ensuring both Units Firmware are up to date.
• Renaming the HDMI 2 Input to DVD.
• Connecting to the other 3 HDMI Sockets on the TV (HDMI 1 has a BT TV Unit connected and works fine)
• Turning On/Off Viera Link.
• I connected my laptop to the HDMI 2 Socket on the TV with the same HDMI lead I use for the Sony Unit and it displays fine.
• Factory Reset the TV.

As a final check I took the Sony Player and the HDMI lead and connected it to my TV in the bedroom and it works fine!

It seems something has happened and now they won’t talk to each other as regards the Video Signal.

I can't understand why the Sony Player works on my bedroom TV but doesn't with my Panasonic TV.

I've proved the all the HDMI Sockets work on the TV using my Laptop.

As a last resort I have ordered a new High Speed Ultra HD 2.0 Cable but I thought I would seek any other ideas people might have while I’m waiting.

Seems like the issue has to do with the Panasonic TV since the system itself works fine with another TV.

Have you tried reaching out to Panasonic support?

Hi Joe

I've also asked the same thing on a Panasonic Forum but not had any replies yet.

As you can see from my fault finding,

"I connected my laptop to the HDMI 2 Socket on the TV with the same HDMI lead I use for the Sony Unit and it displays fine".

So if I play a DVD on my Laptop and connect it into HDMI 2 on my TV it works.

If I connect my Home Cinema into another TV it works.

If I connect them together I get Sound but no picture.

So as far as I can work out it could be either unit that is creating a problem (looking for something specific in the handshake that isn't required with the bedroom TV maybe).

What make and model is the bedroom TV?

Is there any sort of reset on the BDV, apart from the one hour disconnection you have tried?

Here, on page 63:-

I see:-

x [Reset to Factory Default Settings]

You can reset the system settings to the factory

default by selecting the group of settings. All the

settings within the group will be reset.

@JSoapy I'd go with the factory reset as well

Hi everybody

Tv in the bedroom is a Tesco finest Technika

The new HDMI Lead arrived and made no difference.

Apologies I should have said on the original Post I have already reset the Sony Unit to Factory Settings on the initial fault finding.

On advice from a Sony site I set the Video Outputs one at a time on the bedroom Tv and then tried them.

The Video Output Options range from 480i to 1080p including an Auto selection.
One of the baffling things I've found is I currently have a BT Tv box hooked into HDMI 1 and when you initially select that Channel it displays 1080p/50Hz so I thought I would preselect that on the Sony Unit Menu using the Bedroom Tv and connect it to HDMI 1. Still didn't work.

See pictures for the Output Options I've tried them all!

The trouble with these bloody Technikas is that within their own limitations, they can take anything you can throw at them.

If they were horses, then the Technika would be a day-to-day hack, while the Sonys are fine but temperamental thoroughbreds 😛

Maybe try resetting to factory settings then connect it to the Panasonic TV, it sounds dumb, but that's essentially how my PS3 managed to see my new TV (back when the PS3 was itself new 😂)
