Disclaimer:
WARNING! Please make sure that your TV is unplugged, and that you are protected from static electricity. There are various ways to eliminate static electricity, but the most common way is to use a grounding wrist strap. Take photos and notes often to help remember the location and orientation of the parts and wires. And feel free to pause and backtrack through this tutorial as much as needed.

Materials Needed:
To be best prepared to replace the Main Board inside of your TV, you will need the following materials:
• A pair of latex gloves.
• Your ShopJimmy.com replacement Main Board.
• A pair of needle-nose pliers.
• Both a flat-head and phillips screwdriver.

Instructions:
• Locate your TVs identification label and take note of the brand name model number, serial number and model code if present.
• Unscrew and remove the back cover.
• The main board typically manages your accessory inputs and outputs and houses the TV tuner.
• For this TV the Main Board is located on the right side of the chassis.
• Carefully unplug all wires and ribbon cables by hand.
• Unlock the wire connectors by squeezing the tab or tabs and gently remove the wires. Be sure to keep a firm grip with both hands.
• Using your finger flip up the tab on the ribbon connector and gently remove the ribbon. Please do not use a screwdriver to open ribbon connectors as it can cause damage to the pins.
• Unscrew and remove your original Main Board from the chassis.
• Search your TV model number on http://www.shopjimmy.com to find a compatible replacement.

• Click on the search results to view important product specifications.
