Question about Sharp LC-42D64U 42 in. LCD HDTV

Stereo/Mono Fluctuation Screen Display Problem

About once every 5-10 minutes my Sharp LC-42D64U will flash a blue box in the top right hand portion of the screen showing that it is switching between stereo and mono sound settings.

While the sound switch is barely noticable, the blue box constantly poping up in the top right is incredibly annoying.

help please!

    Same problem on the 32" model. Considering using an external cable tuner to avoid this.

    we have the same issue with the sharp 46". Called support and was told our cable power needs a booster. Called cable, they installed a booster, problem persists. Interesting this does not occur when watching a dvd. Still have 70 days to return set and exchange for something else.

    I have an older 32" Magnavox that has this exact problem.  We lost the remote and can't even get to a menu screen to figure it out.  We beg of you to find a solution.

I had the same problem.

All I did was unplug the standard cable wire from my tv and used RCA cables to connect my TV to my digital cable box the the Input 1 jack in the back. It also increased the video quality.

Sharp LC42D64U Wont power on. two lights blink twice then one lite blinks.


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

My new sharp LC-52D65U tv continuously gives the sound display on the top right hand corner when it switches from mono to stereo etc. It dosn't do this all the time but for a while it will start again.


Make sure it isn't the source causing the problem. I.E. Cable box, dvd player, xbox or ps3. Try switching the wires. If all else fails, replace the main board.

My Sharp Flat Panel Television LC19SB25U has Picture but No Audio


Sharp has had a few problems with their audio boards, not finding any bulletins on this model, but a few complaining about low audio on amazon reviews section. If using an antenna you will experience some channels with low audio. If using cable you should get good sound on all channels..
the 9.1 and 9.2 are digital channels and sharp does display them for at least a few seconds when you switch to that channel. Check all your setting in the audio to Stereo never SAP. To options for you are get a cable box, first check in the back and see if there is another coax in, if there are two try both rescanning after connecting.

Is it possible to replace a broken lcd screen on the Sharp LC-42D64U or is it just toast?


Sorry to say, it's pretty much toast. The screen is most of the cost of an LCD TV, so if it gets physically damaged you're better off replacing the set.
