Can you just describe how it would be done then I could tell you if I am able.Then I would just need you to email where to order and step by steps, can you do that?
Expert:  Anthony_Infotech replied 1 year ago.
You need to get the back off the set, locate the mainboard thats the one with all the AV connectors on, unplug and unscrew the board from the chassis, remove the board ,carefully examine the board for its part number usually found on a sticky label on the board or etched on the board, (you may need to go through a few codes before you find the right number)when you get the partnumber try www.shopjimmy.com first, if they dont have it google the partnumber to locate a supplier, its the reverse to fit plug in and switch on TV (plug and play)
The reason why its important to use the partnumber is ***** there may be variants of the board in the same model and they are not interchangeable
Let me know if you need more info

The TV is mounted right now so can't see the back just need to know if the removal is done without having to open the entire TV cabinet?
Expert:  Anthony_Infotech replied 1 year ago.
Oh no you need to get the set down, the back of the set WILL need to come off you cant do anything the set has to be down and in a good position to work on it, above all be careful with the set particularly the panel (screen) make sure you treat that nicely as its easily damaged lay down on a very soft mattress or similar

I see that, when I take the back off are there any wires or cables that have to get disconnected in order to separate the back from the screen?. I messed up iPad glass replacement when I wasn't aware of the wireless antenna
Expert:  Anthony_Infotech replied 1 year ago.
No don't worry its far easier to do this work once you get the back off their is no hidden dangers just be careful at all times with the set, once the back is off you will see how easy it is
