Already know it’s the main board and ready to swap it?

  • Why this upgraded board outlasts the original

    Buy once, fix it for good. Our upgraded mainboard for the LG OLED runs cooler and lasts longer than stock, and is backed by a full 1-year warranty.

    What makes it outlast standard boards:

    • Copper shim + MX-4: We add a precision copper plate between the CPU die and heatsink and upgrade the paste to MX-4 for better heat transfer.
    • Dual-sided cooling: We install a high-end thermal pad on the underside so the TV chassis acts like a giant heatsink, pulling heat from both sides.
    • Proven in the field: Over 200 mainboards shipped for this model, with only 2 boards returned over 2 years. Real-world reliability you can feel good about.

    What you get:

    • Plug-and-play replacement mainboard 
    • 1-year warranty (replace or refund if it fails under normal use)
    • Fast shipping from our U.S. facility

Got your TV open, and ready to swap for an upgraded replacement?
Important Notice
  • The upgraded board may look slightly different and may not have the AV port. It is still fully compatible with your TV.
  • Your Magic Wand remote will not work after this mainboard is installed and there is no way to change that.
  • Your TV will still work with a standard LG remote. If you need one, you can buy a compatible remote using the link below.

Simply works

We sent in the parts and they were assessed.
Seller was prompt and sent out the correct parts.
TV was not hard to fix and now works great with no issues.

You kept checking to ensure that the board was not repairable, which is a lot better than sending it back and I find it was not functioning correctly.

Fantastic Outfit!

Nick’s had prompt processing and SUPERB communication keeping me in the loop on the process and shipping as well as making sure everything was going smoothly. My LG OLED TV works with the refurbished motherboard from Nick’s. I couldn’t be more pleased with the service and success!!!

Ready to be the next LG owner with a working OLED TV again?
