Re: Polariod TLA04011C TV no sound
It is possible that the head phone jack disconnects the internal speakers. You should beable to tell by how the head phone jack is wired.
My knock off Visco LCD TV that is made from china mutt parts (like polariod) had a problem with the onboard amp chip. The "enable" pin needed to be grounded to force it on. If you google the p/n of the audio chip you should beable to pull up the data sheet on it.
I ended up just bypassing the entire on board audio by adding a old PC speaker amp to it. Wired it to the TV's interal speakers, pulled the signal off the RCA jack, and robbed power off the 12vdc side of the power supply.
