TV Main Boards

Buy TV Main Boards Online – Genuine Replacement Mainboards for All Brands

Finding the right TV main board shouldn’t mean guessing or overpaying. At TV Parts + US, we stock a huge inventory of replacement TV mainboards for the brands people search for most – Samsung, TCL, Vizio, LG, Sony, Hisense, Sharp, Toshiba, and more. Whether your television has a dead screen, won’t power on, has no picture but has sound, or keeps rebooting on its own, a faulty main board is usually the cause and replacing it yourself is often cheaper and faster than a technician visit.

A Samsung TV main board replacement is one of our most requested repairs. Samsung mainboards control everything from signal processing to smart features, so when the board fails you’ll typically see symptoms like a black screen, frozen apps, HDMI ports not detecting devices, or the TV stuck on the logo screen. We carry genuine and OEM-equivalent Samsung boards matched by exact model and part number, so you can be confident the replacement fits and functions correctly the first time.

If you own a Vizio TV main board replacement part number and need it fast, we’ve got you covered. Vizio boards are known for handling both power and video processing in many models, and a failing board often shows up as flickering, no backlight, or a TV that clicks but never turns on. Our Vizio inventory is organized by exact board number so you can match your old part quickly and avoid ordering the wrong component.

We also carry a wide selection for a TCL TV main board replacement, covering Roku TV and Google TV models. TCL mainboard failures commonly appear as apps crashing, a black screen with audio still playing, or the TV not responding to the remote. Because TCL updates their board numbers frequently across model years, we recommend checking your TV’s rating label for the exact part number before ordering to guarantee compatibility.

Every TV main board we sell is tested for functionality before it ships, backed by our warranty and price-match guarantee. Not sure which board matches your TV model? Our team is available at (+1 819-329-9813) to help you cross-reference the correct part before you buy,  so you order once, and order right.
