LC-52D85UN making different software sharp boards WORK
i promised myself if i made this work i would share it with you all and it did so here it goes.
finding the right board number may be easy but matching your software numbers are not always available. it can be pretty frustrating so after checking out the service manual and finally locating the program IC i was able to pull the IC from the old board and place in into my new board. this is IC8453. its on the bottom side of the board under the metal casing. attached pictures as well. easiest way to remove is just some hot air take your time dont heat it too fast or too long. then clean the paths on your new board and solder/flux away. check connections with a 10x loupe and your all set.
models included with this board number are
LC-46E77UN
LC-46SB57UN
LC-52E77UN
LC-52SB57UN
LC-C4677UN
LC-C5277UN
LC-52D85UN
The board i had was damaged due to a surge and was a DUNTKE833FM11 but the only board i could find out there was a DUNTKE833FM07. set is working great now. hope this helps someone out there.
