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

1 Answer

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 the same problem with 32" model only the box is constantly flickering on local channels and frequently on some satellite channels. Does anyone have a solution??

    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.

I have a Sony WEGA KDE-42XS955 that takes 5 minutes for the picture to appear. Once it appears..works great! If I just leave it turned for it will work fine. Any idea what board needs to be replaced?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
