I bought a Sony Bravia 42" LCD Digital Colour TV in April 2008.

Customer Question

I bought a Sony Bravia 42" LCD Digital Colour TV in April 2008. It has functioned without any problems ever since and I currently receive my pictures through Virgin Media.
Today I took (on approval) receipt of a Bose Solo TV Sound system. This offers three connections to the TV - optical digital (1st choice); coaxial digital (2nd choice); analog stereo (3rd choice).
Having looked at the available connections on the back of my TV, am I right in concluding that only the third option is available to me ? Should I be using the connections marked E or H on page 16 of my Operating Instructions or am I missing something ?.
Please advise

Hello, I'm TV Tech1 and I'll be working with you to identify and help you resolve your problem.


I can look at the options that Sony provided on your TV set, if you can find your TV's model number. It should be on a sticker either on the back or you may find a smaller sticker located on the right edge of your TV frame. Most Sony models start with the Letter KDL 50W3000 or KDL-46L2610


That should help us connect your Bose soundbar up to the TV set correctly.


Also note that some of those optical outputs....they only work with the HDMI connections, and not with the Scart or the Component inputs on the TV sets.


There was a time when only the Digital cables connected to the Digital outputs and the older Analog connectors like Scart and Component worked with the RCA outputs.

That's why we need the model number.

Ok, I just wanted to make sure this was the only question you had asked --


You may have had 2 questions on the same model, but it isn't showing up in the list of questions you have asked.


Connection H -- That's the only audio output on your TV set. Connect your soundbar to that connection.


Then go into your Tools menu, select the Sound settings, switch your speaker setting to Audio System to turn on the Audio Output (H)


Now, IF you have any SCART or component connected devices....try those FIRST, then try the HDMI next, but only IF the HDMI doesn't deliver sound to your BOSE.


Now the reason I state that is because the older RCA Audio outputs....the HDMI audio was never delivered to that type of connector. Since I don't see BOTH connectors (optical and RCA audio OUTPUTS on this TV), I can only assume that Sony was licensed to deliver BOTH types of audio to the RCA outputs.


The KEY is the Licensing. Everything has slowly migrated from RCA to Optical, and then ALL inputs moved to ONE AUDIO OUTPUT.

That's part of the Key issue....knowing when you set your TV's speaker setting to "Audio System" -- Do both HDMI and Scart/Component deliver to that output, or does only Half of the connectors do it?


Get that connected to the RCA audio outs (H) set your TV's Speaker setting to "Audio System" then try the HDMI, and then the Scart/Component inputs.


2007 was one of those years where they were transistioning to One output for all. But like I said, it was a slow process over 3-4 years.


Let me know the results you get with HDMI and Analog - Scart/Component, ok?
