We just bought a new 52 inch Sharp LCD and the right speaker is muffled. Is this common? How do I fix it? Should I just take it back?

It will be expensive and time consuming, but it can be done. There are many web sites that sell replacement screens. Just google TV replacement screens. You should download the service manual for your TV from Sharp's website before attempting to do the repair.

The cost depends entirely upon which country you're in, but there is one universal truth: it's always cheaper to replace the tv than to get a new screen fitted when they're that big.

The lcd panel is overwhelmingly the single most expensive component in your tv: when you bought your tv, you were effectively buying an lcd panel at a huge volume discount with all the other parts thrown in for free. Supplied alone, the panel costs almost as much as the tv but exceeds the cost once skilled labour charges are added.

Have you fixed this? Are you willing to sell this? I am looking to salvage some parts.

I had the same issue with my Sharp Aquos 52 inch LCD TV. I called Sharp. The tech had me unplug my TV, take the batteries out of the remote (TV remote not cable) and press all buttons on the remote (including the buttons under the flip top at the bottom of the remote). I did this, put the batteries back in and plugged in the tv and everything worked. I had gone 4 months having to use the surround sound for volume and turning the TV on and off by hand. This took 2 minutes to fix.

hookup tv with HD signal or off air antenna

Hi jmartinezua,

Here is how you fix this:

Go to menu--> setup --> reset

This will reset your TV to factory settings. The Demo Mode will cease.

If it it new, take it back. The product is not working properly.

Replacing the cable box may fix the problem. But, you're the 4th person to have this same problem with this SHARP TV MONO only audio.
Try system reset button on the back of the TV or the box.
