I have a 50" that keeps popping up the 3 choices of headphone soundboard or TV control of the volume. It pops up for a split second and times it will stay on the screen for a few seconds.

Hi, go into your menu and turn off closed captioning, it may be marked "cc" or spelled out as "captioning" but either way just turn it "off" and end of problem, Happy Holidays, BMW Rider

Hi,

Press the Menu button ( marked OK) for one minute, or more, and a blue/red menu list should appear on screen.

Using the adjust button (immediately to the left of the OK button) by pressing the arrows at each end up or down as required you can enter the menu and select an action by scrolling.

At the end of the list of possible adjustments on the left of the screen (brightness, contrast, etc) is the Reset section.

On the righthand side of the screen is a flashing Yes No choice which automatically alternates.

The trick is to select the Reset choice on the left and while selected press the OK button when the Yes alternative on the right of the screen is flashing.

You VDU should then Reset and all will be well.

What you all need to do is get away from a coax cable connection. If you have a cable box, or satellite box, take the coax cable off and use red, white, n yellow rca composite cables to connect your recievers to the tv. if you dont have a cable box, either get one, or get a converter box and use a tuner outside of the tuner within the unit. The tuners in those tv's are built to show you when you experience signal fluctation(which is normal with a coax cable) and thats why the box keeps popping up on its own. good louck to you all with this problem

Try putting pressure on the monitor near the buttons. There might be a short or some type of stress pressing the buttons.

Estava também com o mesmo problema de voces, já estava irritado, então abri o monitor e desconectei a ligação com a placa de controle dos comandos dos botoes do menu. é fácil fazer. Só que não vai funcionar mais os botoes. pelo menos essas mesagens não vão mais incomodar.
