Can't connect wireless stereo to sylvania 6620LF4

I am trying to connect a Sony wireless headphone system to my Sylvania 6620LF4 TV. The only way the headphone will work is if I plug it into the headphone jack on the TV, but then that cuts out the sound from the TV speakers..Any suggestions on how to hook this up?

Hi, Ok, I now understand what the problem is. Sorry I missed the fact that it is due to no audio outputs on the TV. The audio board is designed to power low impedance speakers and doesn't have a big power amp to drive them. I do not have a schematic of that particular TV so I do not know how the headphone jack is wired. The way it basically works is, when you insert the plug, the tip pushes a contact away from another contact thus making one circuit and breaking another. You can test this externally by inserting an unwired plug or look at it from the inside and bridge the tip connection. I would only advise this if you have some technical skills. Other than that the thing is working like it was designed, they don't want you to use both. Sorry, I hate to give this type of news, but I am one of the only ones who will. Good Luck to you!

You can hook this particular unit up to your stereo reciever if available. if i am not mistaken the original design purpose of these headphones were to be powered through a stereo reciever, at least it is a sure fire way of keeping your tv's sound in tact and using the headphones when needed. most receivers have a speaker a and speaker b configuration if you attach the lead from the headphone unit to the opposing speaker input then you can have the functions you desire and the performance you have indicated. hopes this fixya.
Best regards
Ryan

Need code for universal remote Sylvania LC320SL8


We bought a Sylvania LC420ss8 HDTV.

Our current universal remotes would not work, I followed the advice on this site and got a Sony
RM- VL600 Sony Untergrated Remote Commander, use page 16 in the manual to teach the new remote off of the remote that came with the TV. It really works. I am happy with the tv and remote.
