Quality Service! Brought color back to my Vizio M3D470KD that I purchased in 2012 for a decent price. Can't get 3D TVs these days so it was nice to get it working properly again.
Thank you 🙏 done in timely manner. Great communication. I will definitely refer you guys !
Would have liked to have a more detailed explanation of what was wrong and what the repair process was.
Hello David,
I apologize for not providing more information in your ticket regarding the repairs performed to your unit. We don't always provide that information as it can get technical but also because we do already have the information provided on our Youtube channel showing exactly what parts are replaced and why. For your unit specifically, I have reviewed my technician's notes, and they stated they found an issue with the clock line signal being out of spec. This caused the processor to be unable to properly communicate with the rest of the motherboard thus explaining why the unit was unable to fully boot up. In order to resolve the issue and bring the signal back within spec a pull-down resistor was installed.
Additionally, the CMOS battery was changed as they typically due fail after 10 years.

Although their system to keep me updated of my units problem and fix didn’t work very well their repair was top notch! I could see no physical evidence of the repair on the motherboard chip. I’m told the chipset that failed was a surface mount chipset. It required specialized equipment to remove and replace this chipset that would apply heat to de-solder the tiny pins and allow removal then reverse the process to solder the new chip in. This was all handled without issue as the motherboard look brand new as far as I can tell. And their return shipping was very fast! The NAS works. I’m very happy with their service.
