If your television emits sound but does not display visuals and all TV the settings are correct, this guide explains how to replace a faulty motherboard.

The capacitors in televisions can store a potentially fatal charge for several months after the TV is unplugged and must be properly discharged to safely handle the motherboard.

    • Before disassembling your television, ensure that all cables are unplugged from their power source to avoid serious injury or death from electrocution.

    • Lay the TV flat with the screen facing down.

    • Remove the four, 12mm Phillips #2 screws from the back of the TV stand. Support the TV from underneath as you remove the screws, so the bottom does not fall on the table.

    • Remove the stand by lifting it away from the TV's backing.

    Do you like playing game? What kind of games do you usually play? If you want to find a new game that is still very familiar, try play solitaire.

    • Caution: Before you remove the motherboard, be cautious of the many capacitors throughout that could cause serious injury or death. Use a discharge probe to safely rid the capacitors of dangerous charges. The following link provides an instructional video for how to properly complete this step: https://www.youtube.com/watch?v=M-AIbrbT....

    • Wearing rubber gloves and rubber soled shoes while working with and near the capacitors ensures greater safety and protection against electric shock. See iFixit's Project Safety page for additional safety information.

    • Remove the motherboard by gripping the rubber stopper as shown and lifting the motherboard up out of its plastic housing.

    • Carefully flip the motherboard over and locate the nineteen capacitors.

    • Notice the six cables attached to the motherboard. Pull on each cable connector with moderate to heavy force to remove them.
