HOT TIPS

Power On Problems: (see page 2) Video Problems: (see page 3) Other: If the set loses internet connectivity, the remote control no longer operates, and the 3D glasses will not link to the set, verify power supply voltages. If they are normal , replace the main board as that is the only commonality between all of the failures.
