Hi , I`m jack

Perhaps I can help you with this and I`ll start by saying that NO you will not have any picture going through if you don`t have the correct board hence it will look exactly like the same problem .

This is not like it work half or not properly , this is it works or not at all so it will look exactly like the same problem .

You need the correct board

Which one of those is yours , click this link ;

O.k then a few question on that

Expert:  Jack replied 1 year ago.

Could you see the TV's own menu with the original board ?

Expert:  Jack replied 1 year ago.

For that matter just re-install the original t-con although having some backlight and sound does sound like a defective t-con but one test is the TV's own menu .

If you can still see it then the main board is suspect

Sorry, i wilI have to get back with you on that.
Expert:  Jack replied 1 year ago.

no problem but as I said above if you cannot see anything including the menu then you were on the righttrack about the t-con otherwise its a problem with the man board video processing the signal from external inputs if the internal menu can still be seen .

Use the link I gave you to ID your board and then use that part number to find it or let me have it and I`ll find it for you.
