Hello , my name is Jack
Perhaps I can help you with this problem but first i would have a few questions;


When you say that the screen " blacks out" , do you mean that the screen goes blank with some background light or completely dark like when the tv is off ?


Did this problem start all off sudden/overnight or just slowly got worse lately ?

Customer: replied 3 years ago.

The screen goes blank with some background light. The problem started all of a sudden.

O.k then I do have some info about defective lcd controller (t-con) boards for this model.

I will lookup that board but I would have another question;


Did you wish to look into repairing this yourself or just have an idea of what is involved and the repair costs ?


Customer: replied 3 years ago.

repair myself if possible.

O.k then i will give you the info in both cases and then you can decide .


First thing will be to remove the back cover to locate this board under a shield in the upper center at the back of the screen then you can buy it at the link below;



To have this repaired at home by a shop , you may be looking at around 250 to $300.


If you go for the repair shop option then click on the link below and enter your zip code ;

This will give you a list of repair shops in your area.
You could give a call to different shops in your area to get an idea of their rates , this is a bit like buying insurances , it pays to shop around.


Hope this help and please take the time to rate my answer if that answers your question , otherwise do not rate at all , just let me know and we`ll see what can be done.
Note that you can reach me here at any time after rating if you have questions.
