Your TV probably needs this board if you see any of these symptoms:

  • TV is dead / No power
  • TV has power, but won't turn on
  • TV Shuts itself off as if it's overheating
  • HDMI failure
  • TV turns on but is stuck on Logo
  • Other symptoms? Fill out the form and a tech will confirm if this board is right.

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.

LG Repair of 65 inch OLED

Nick’s electronic repair saved my 65inch LG OLED! Board worked perfectly and they were very thorough in their response about what they could do. Cheaper than the OEM part that is apparently doomed to failure without some modifications. TV wouldn’t stay on for more than 2 minutes and now it is back to being used by the whole family for many hours a day without issue. Would definitely use them again if another system went down. Nice to not be oversold on anything and have courteous and professional interactions from start to finish.

Excellent Service

I ordered this mainboard after speaking with Nick's about the issue I was having with my television. The part arrived in a timely manner and was easy to install following the video instructions from Nick's on Youtube. TV is better than it was when new! Thanks to Nick's Electronics, great service!

The board was easy to install and works flawlessly. Looks like I should get a few more years out of this TV, my old board looks to be in good condition with no browning under the cpu, is this a candidate for a solder re-flow / re-ball?

Possibly, however, we no longer offer the repair service for this exact board, as the only way to really properly fix this board is to replace the CPU, which is no longer available for sale.

Great resource for PCB work

Quality detailed PCB repair with thoughtful upgrades to prevent future failures. A great resource if you don't have tens of thousands of dollars of specialized equipment for making your own repairs.

Crucial fix for expensive TV

My LG OLED is only 4 years old and we ran into an overheating issue on the mainboard which rendered the TV mostly useless. After a lot of research, I came across Nicks and figured it was worthwhile to spend $200 to fix a $3k tv. Tremendously happy that the repair worked and will likely keep the TV running for years to come. I will definitely come back to Nick's with any future issues!

Works as promised

The best I could hope for - delivery was on time; product was well packaged and ultimately fixed the issue with the display panel.

Excellent Service!

I sent the main processor board from my LG OLED tv to Nick's Electronic Repair for testing and repair. After the module proved to be damaged beyond repair, Nick's Repair offered a refurbished board for a small up-charge. The replacement board functions perfectly and is a newer model to boot. I highly recommend Nick's Electronic Repair.

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