Here’s a summary of all the boards and their part numbers;
Power Board Part # 09-60CAP000-00
Main Board Part # 01-60CAP001-00
Controller Board Part # RUNTK5261TPZC Look for the ZC stamped on the board.
The controller board is manufactured by Sharp and their name is stamped on that board. I’m told that the main board is also manufactured by Sharp though their name is not stamped on this board. The power board could be manufactured by anyone and I could not find any clues as to who manufactured it as there are no markings as to name on it.
The main board connectors are simple to remove if you are changing that board, simply push in and hold the black plastic tabs on the sides and pull the connector out. The other connectors are similar to automotive types with a locking tab on center top that you push down on and pull out, please note that you do not pull on any wires to get the connectors out, pull from the connector itself! Here’s a pic of the main board up close with all the connectors plugged in.
You can click on these pictures for a larger view. The connectors on the left side of the board go to the controller board. The connector at top left comes from the power board and supplies operating voltage to this board. The connector at top right with the blue marking on it goes to the PC board on the side of the TV for power on and off, channel up and down, and volume up and down. the connector on the lower left goes to the speakers on the TV. One very important connector is the WiFi antenna connector that looks like a ground tab that pulls up from the board, it has a button on the bottom which pushes in straight down and pulls up straight up to disconnect. This can be seen in the pic on the lower left. The label says that this is the antenna for WiFi and it may be even though it goes to the frame of the panel, I guess it uses the frame as an atenna even though it looks like a ground cable.
