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. Link to remote

OLED FIXED
Apparently LG under engineered the main board of the 65inch OLED. It is prone to overheating and failure. Mine is only 2 years old. Thank you for repairing and adding heat resistance to the new board. Hopefully I can get many years out of the incredibly expensive tv. SHAME ON LG.

Great communications, quick service, quick return of the repaired product. I thought I’d have to replace my 4 year-old tv. Nope! Nick’s got me back up and running within a week from first contact to my repaired part arriving at my home. These folks know their stuff and do it very well!

Nick's Electronic Repair did an awesome job repairing our TV part all for a fair price and fast turn around time. I reinstalled the part in about 15 minutes and had the TV working again in about 15 minutes. Great job, Nick!

Hi,
My replaced ECM seems to work fine, with the car back to normal.
Thanks. I am glad that your business exists to do these repairs.
But, does the photo attached look like a $637 repair/replacement?
The one I sent looked nearly new.
I took 20 minutes and cleaned it off because I couldn't stand to look at it like
it was on arrival.

BETTER THAN NEW
My 77”Samsung OLED died at exactly 13 months old. Samsung refused to replace or help in any way. They were extremely rude. This TV was a gift as I’m retired and struggle financially so I was broken hearted and very worried. I can’t afford a new tv but after about a month I found NICKS online. I ordered a refurbished one connect at 3AM Wednesday and it was at my door on Friday morning. I brought tears to my eyes I was so relived. It’s my only source of entertainment as I live alone in a very rural area. Thank You NICK
for all you help. I was really dreading this long winter ahead without a TV. I know now there’s a problem with this model so I hope it lasts me. I’m using it carefully. I pray your company is a huge success for you and your family. You don’t realize how much help you provide for some of us .afain, Thank You
Very happy with the parts, the video showing how to repair it and the support I got when I had questions. Excellent. Thanks for all your help

Outstanding Work and Service — Couldn’t Be Happier
I had Nick’s Electronics build a fully restored and upgraded original Xbox for me, and I honestly couldn’t be happier with the entire experience. The quality of the work was outstanding. The console arrived incredibly well packed, exceptionally clean, and everything about the finished build felt professional and carefully done.
They completely serviced the console, recapped the motherboard and power supply, serviced the disc drive, installed the Stellar HD+ setup, upgraded the storage, and added RGB lighting. Even the small details were handled extremely well. The disc drive runs incredibly smooth, the HDMI output looks fantastic, and the purple RGB lighting they set up for me was a great touch.
Communication with Juan was excellent throughout the process. He was knowledgeable, straightforward, patient with my questions, and gave recommendations based on what he actually thought would work best rather than trying to upsell me. That goes a long way with me.
The finished Xbox exceeded my expectations enough that I’m already talking with them about having an Xbox 360 built next. I wouldn’t hesitate to send them another console or recommend them to anyone looking for quality repair, restoration, or modification work.

It worked!
my TV did not have any power I stumbled upon Nick‘s repair on YouTube. I was skeptical at first I called around TV shops nearby. None of them had either had the parts or we’re charging me too much or did not have a warranty system in place luckily I found this I was able to reach out to Nick. I wasn’t sure if it’s my power board or my main supply board. They responded back saying if you send both we will charge you another $30 to check both Out. Very simple. Sent them both out. Got it back plugged it in and it works. Thank you very much Nick’s repair.

Repair > Replace
A great product supported by an outstanding video guide. I have experience soldering and desoldering, but I leaned some new desoldering techniques from Nick’s Electronic Repair videos. The video guides are very thorough and I was able to replace the display in about an hour end-to-end. Thank you for helping me breathe new life into my 23 year old range.
