NO PIC-NO AUDIO - Polaroid TDX-03211C LCD TV

The sound card in the computer could be damaged.

The audio drivers might not be properly installed.
First, check for windows updates and install any that indicate they are for your sound card/audio driver. They may be listed under optional updates.

Next, open Device Manager (search it in the start menu) and expand Sound, Video and Game Controllers (see pic). Right click the audio driver (Realtek High Definition Audio in the pic for example) select Uninstall. When the device is gone from the list, select ACTION at the top, then select SCAN FOR HARDWARE CHANGES. Give ti a restart if that didn't work.

Good luck!

I would need a pic of the audio and video inputs on ur TV and a corresponding pic of the audio and video (video card) outputs from your computer.
What operating system do you run?
FYI first step is to see what cords would be needed 2nd step is to configure the video output from your computer.

I need pic of 16 pins in back connected to harness
or I need pic of harness and wires mines beat here

please and thank yall

Have you checked to make sure everything's plugged in right? Are you sure it's on the right channel?

for your picture to be hdmi you need to buy a hdmi cable. For analog audio you need to be an attachment or adapter for your audio

power supply not working -- did you check internal fuses on board --? if everything checks alright - replace the power supply board

Have u ever plugged in the HD cable or fiddled with the output settings...?

My remote is not working

You have a picture when you're watching a DVD, but none when you're watching regular cable? Does the audio appear to be okay?? Are you sure you've switched the inputs on the TV back to main???
Let me know..
