model LC46D43U just about 3 years old.

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.

Since the TV just went out a warranty last month, do you have a ballpark figure what it would cost to have someone take a look at it? Unless I can narrow down an exact problem I won't know if its worth fixing. Merry Christmas, huh?!

What warranty did it go out of? (who was the warranty through)


Normal house call is around $50-$100 depending on the part of the country you live in.

It was an extended warranty that I purchased from Sears when I purchased the TV. And I actually to the have the board replaced a year after I had the TV due to poor sound. Which never really fixed the problem it actually sounds as if the speakers were blown even before I used the TV...crazy right?! Oh well, maybe it's just time to buy a new TV? How long should they typically last?

Unfortunately these LCD televisions only typically last about 2 or 3 years it seems. For whatever reason these sets do not last like they should. If you decide to get a new set I would recommend a Sony LCD with a 5 year warranty this time.


I am sorry for the bad news.
