Sony Xperia Z Tablet - Black screen on TV when using MHL adaptor

[mrpxl17]

Hi, I have now bought 3 different MHL cables 2 from ebay and 1 from Amazon. All stated they worked with the Sony Xperia Z tablet. But when ive tried it all i get is a black screen. Ive tried on 3 tvs using different HDMI cables but with all 3 adaptors i only get a black screen.

Has anyone else experianced this who could tell me where im going wrong

Many Thanks in advance

Pete

Some MHL-adapters needs power to work. See if your adapters have any power connection and try connecting them to a power source.

If you for example use our MHL-adapter (http://www.sonymobile.com/global-en/products/accessories/mhl-to-hdmi-adapter-im750/) there's a microUSB on it where you connect the phones charger.

Hi Rickard,

Thanks for your reply. Ive plugged the charger i got with my tablet into the usb port on the all MHL adapters ive tried but i still only get a black screen.

When the charger is not plugged in i get a No Signal message on my screen and when i plug it in all i get is a black screen

Are your adapters 5-pin or 11-pin? For Tablet Z you need a 5-pin adapter.

All the adapters that i have purchased have been 5 pin adaptors and have had Sony Xperia Z as a compatable device in the listing. Is there a difference with the Xperia Z phone and Xperia Z tablet?

[Rickard]

No, Xperia Z and Tablet Z use the same MHL-connector.

Could you try your adapters with another Xperia device (that supports MHL) or try your tablet with our adapter to see where the problem is? A service location should also be able to assist you with testing your tablet and see if MHL is working as it should.

I dont currently have access to another xperia product but i will see if can find someone with one that could test the adapters. The service centre option might be best for me. How do i find my local one. I currently live in Manchester in the UK

I don't have any list of service centers in the UK unfortunately but you can contact your local Sony Xperia support for this information: http://www.sonymobile.com/global-en/support/contact-us/country/en_GB/

What you also can try if you haven't done that is to update/repair the software in your tablet. You can do that using PC Companion: http://www.sonymobile.com/global-en/tools/pc-companion/

Just to update all. This issue was down to the Tablet not the MHL Adapter.

I spoke to the Xperia care team who advised that i do a repair / rebuild with the sony pc companion. After i had done this i tried the MHL adapter again and hey presto it appeared on my TV Screen.

Big thanks to the xpera care team and also to Rikard for all there help.
