Since you tapped the speakers directly the signal may be too high. Maybe add an L-pad inline from TV to receiver? https://www.google.com/search?q=L-pad+volume+control
As to the DAC, Amazon has many closer to and under 20 bucks. Example: https://www.amazon.com/Best-Sellers-Home-Improvement-Digital-Analog-Converters/zgbs/hi/306898011
Hello experts. I have a 2009 Panasonic Viera Plasma TV that sadly has no analog audio out ports. I want to hook up to my (newer) LG receiver that sadly has no digital in ports. In the past I had a tv with no audio out and I was able to splice into the tv’s speaker system with a female 3.5mm Aux socket and connect it to my receiver.
I did the same thing with this Panasonic, but unfortunately the protection comes on whenever any sound with any type of bass comes through. Is this a grounding issue? (Combining the grounds of both speakers into one on the Aux connector) Or am I doing something wrong?
First, the reason I have this combo to begin with is because I was using a smaller tv that had an aux out port before I bought my receiver. I was recently gifted this plasma tv. I didn’t even realize the LG didn’t have an optical in, as I’ve never used a digital connection before.
I originally researched a digital to analog converter, but seeing as how the only electronics store in my city is Best Buy, I don’t have $100 to fork out to buy a converter locally. I priced some affordable converters online, but the performance reviews were too inconsistent and I didn’t want to waste time and money guessing.
I mainly want the tv hooked up to the amp because I’m into music video games - Rock Band, Amplitude, etc., and the tv speakers alone aren’t enough. The additional problem with converters is the extra lag. A few milliseconds isn’t much with watching tv or even most games, but when audio/video timing is at play, it makes a big difference.
Also, i was able to install this connector using parts I already had around the house, so it didn’t cost me anything. I desoldered the wires from an old headphone splitter, and soldered some house speaker wire I had laying around. I used hot glue between all the connections to ensure they wouldn’t touch. Then I covered it in heat shrink tubing - two layers. I spliced into the actual wire of the tv speakers - at different lengths on each wire so that they can’t touch. I didn’t actually cut the wires, but rather stripped back the insulation and wrapped the wire from the aux connector around it. I then put a dab of hot glue over each splice. From there I drilled a hole in the metal plate that covers the input/output board on the tv, just larger than the aux connector, pushed the connector through, and used hot glue on the under side as a brace. For the top side, I added a piece of heat shrink to help stabilize the connector and ensure it wouldn’t push into the tv. It’s an extremely solid connection.
I’ve wired many headphone connectors, both male and female. I’m confident in my work. I’m just not sure what the problem is here. I don’t want to have to add more to my system than I already have, and I feel the fix is probably something rather simple, but unfortunately I don’t have enough experience or knowledge of electronics to understand what would cause this.
Thanks for reading my long post - I’m trying to cover the answers to any questions that may arise, and I appreciate any help that can be given. I can take pics or go into additional detail if needed. Just let me know.
