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
