As to the claim you can't splice, I can only can guess you haven't found a good tech.
For 'leventy-7 years, every TV I've bought has a Sony headphones jack on the face that shuts off the internal speakers and sends the audio signal to my headphones. With my hearing aids, I need headphones for clarity.
Just bought a P42UT50 Plasma TV, got it home and discovered that it does not have a Sony jack for headphones. My not-so friendly neighborhood TV retailer asserts that the TV industry has stopped including this feature, and furthermore tells me that it is not possible to install such a female jack by simply opening up the case and splicing in the connector.
My TV is hooked up to an HDPVR for high def screen display, the whole reason why I bought this TV.
The reverse of the TV has a digital audio out jack, which when connected to a digital to analog converter does not work well at all, really poor sound.
The back of the HDPVR has both RCA audio out and digital audio out, but neither of them work because the HDMI connection directs all signal through it, mandatory. So both the RCA and digital audio outs are silent.
I have 4 good quality headphones, 2 with stereo Sony male connectors, one with R/L RCA male connectors, and the 4th one with USB. All work normally. None have in-line volume control, never needed.
I really do not want to have to go to the expense of a home theater audio system, just so I can plug in my headphones.
You would not believe the runaround I'm getting talking with various techies. Is it possible that I am the first person to ask this question? Hardly....
Basic question - How do I get back to what I've always had - headphones that redirect audio from internal speakers to the headphones?
Thoughts of others?
