-What is the model number for the television? (this can be found on the back of the unit)
-How old is the unit?

When you loose picture, if you press the MENU button on the tv itself, does the menu show up?

There are a couple of things that could cause this, unfortunately there is no reset for this television other than unplugging it. 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.

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.

the answer you gave is acceptable and i would like to ask you if by any chance i will have somebody look at it and find out that it was'nt the capacitors or what ever it is will i still get charged for $175-$200 just for trouble shooting,what about if they found out that it was the back panel that has a problem? you also mention that the panel worth at least $800,does it mean just get rid of the tv and just buy a new one,i would really appreciate if you could give me an option or suggestion,shall i go for a teach to trouble shoot first or just buy a new tv
Expert:  Tim Nolan replied 3 years ago.
No you should definitely not get charged that much for troubleshooting, an average house call fee is around $75 which is all you should get charged if it ends up being the panel.

Yes if the lcd panel is causing your problem you could easily throw the tv out and get a new one.
