TV Main Boards for Sharp

What You Need to Know When Choosing a Sharp TV Main Board

Sharp, founded in 1912 in Japan and has been making electronics since then. Sharp makes Smart 4K and FHD televisions in sizes ranging from 28-inch to 65-inch curved screens and has made a variety of LED, LCD, and plasma televisions. If your Sharp or Sharp Aquos TV doesn't turn on, or shows unusual coloration or altered images or shuts down unexpectedly, you may need a replacement mainboard.

The TV main board is also referred to as a circuit board or a "motherboard." If the component is malfunctioning, signs might include:

• Not turning on: The TV won't power on with the remote, and the LED indicator doesn't respond.
• Shutting off: The television shuts off by itself while switching channels.
• Getting stuck: The TV turns on but is stuck on the brand logo or a blue screen.
• Strange noises: The TV makes a loud noise then shuts down. HDMI inputs do not operate.
• Not opening apps: The Television will not open the internet apps it usually runs.

Owners are advised to match the exact appearance and part number when selecting a replacement part for the brand's LCD or LED televisions, not just the model number. Several different main or "motherboards" may be used in the same model of Sharp television. The manufacturer's part number for the main board will be printed on the component, which is located inside the television, and the part number will also be screwed to the chassis and connected to other operating components of the television.

The main board is located inside the television. Follow these steps:

• Step 1: Unplug the television and put it face-down on a soft, secure surface.
• Step 2: Remove the screws that secure the plastic television housing.
• Step 3: Open the television and locate the board with audio-visual inputs, including HDMI and USB ports.
• Step 4: Identify the board part number, which will be printed on a barcode label or directly on the board.

Television main boards will be identified by part number. Several different parts are used to serve different models of the brand's televisions, including LCD and plasma televisions. Note the exact manufacturer part number of the component attached to the television chassis. Match the exact part number, appearance, and specifications of the main board when selecting a main board.

Prepare to replace the board by having gloves, the appropriate replacement part, needle-nose pliers, and flat-head and Phillips head screwdrivers. Remove the TV case and locate the board inside the chassis. Carefully unplug all wire bundles and leads from the board. Unscrew and remove the original board. Replace the new part and restore the connections. Configure the board following manufacturer set-up instructions.
