I am noat sure if the menu button has color . I will have to look tonight when I go home. I am at work now.

The unit is aprox. 5 years old. It is a 28" screen.

I can't get any thing. The screen stays black with no sound when I try.

During the time I was trying to get it to work, It tried to go on 3 times once with only sound, the other times it was flashed of light. they only lasted seconds.
Expert:  Tim Nolan replied 4 years ago.

Ok well lets test that menu and let me know when you get home. I will be here for about 3 or 4 more hours. Will you be home by then?

I finally found you. The menu button is below the sat. button on the channel changer if I press the sat. button first the menu lights up red. the menu on the TV set does not light up. nothing on the board below the screen that lights up. ...Dorothy

Dorothy,

 

I am so sorry, I have been away for a family emergency for a couple of days, I am back now and greatly appologize for the dealy in my answer.

 

 

There are a couple of things that could cause this, unfortunately there is no reset for this televisions and it will have an internal failure at this point. I will try to explain the possibilities the best I can.

 

First you could have a failure in the power supply, we have seen some capacitors fail in your model and cause funky problems like this. If this is the case you could be looking at somewhere around $175-$200 to fix the set. IF the power supply had to be replaced you could be looking at $350

 

Next could be the main board, this would not be good news because you could be looking at $400-$500 for the repair (I know this is up there in the price range and most likely getting over the cost of a new set)

 

Lastly you could have a problem with the panel itself, this would mean a new set for sure because the part cost is more than a new set. The panel in your tv is about $800 just for the part.

 

Any of these could cause your problem, but it will require troubleshooting to determine the exact cause of your problem. If you have experience, and test equipment and would like to attempt some troubleshooting I will be happy to assist you, however if you do not have equipment or experience then you would need a repairman at this time to get an exact diagnosis. I am sorry that I don't have a quick fix or easy answer for you on this one, it is definitely an internal failure.

 

 

If you would like any additional information or have more questions please don't hesitate to ask!
