Einleitung
Follow this guide to replace an old or faulty motherboard in your Samsung BD-JM57C Blu-ray player.
The motherboard in the Blu-ray player allows all the other important components such as the disc drive and Wifi card to communicate with one another. An old or faulty motherboard will prohibit these components from communicating with each other resulting in a Blu-ray player that will ultimately not turn on.
Before taking apart the Blu-ray player and replacing the motherboard, look at the troubleshooting page for the Samsung BD-JM57C and see if your problem can be resolved.
