Resolves common "boot loop" issues and YouTube playback errors.

Press and hold down the physical directly on the television's side or bottom control panel. Do not use the remote control.

This update can turn a dead monitor into a functional unit, saving you $100+ on a replacement mainboard. However, because CVTE is an OEM, you will not find the update on an official website. You must rely on technician forums, panel databases, and careful version matching.

The USB drive must be formatted strictly to the FAT32 file system.
