The problem occurs when the TV downloads an incorrect update, causing it to malfunction. Error code 2014506-1 indicates a mismatch between the model number and serial number of the TV. If the mismatch is not critical, clearing the cache memory may help, as the cached TV information does not match the downloaded information.
To do this, hold down the power button for 20 seconds while the TV is on, or unplug it from the power source for 30 seconds. You can try performing a factory reset through the regular menu. If this does not fix the problem, you will need to perform a factory reset through the service menu under Options - Factory Reset (hidden menu). To learn how to enter and work with the menu, you can find it in the guide.
When solving this problem, the technician checks the model number on the sticker and compares it with the number in the TV menu. If the numbers do not match, they enter the engineering menu and perform a factory reset. This reset restores the TV to the first OS reference version loaded at the factory.
The reason the TV downloaded the wrong update can be difficult to determine. It may be due to a mismatch between the model and OS version on Samsung's servers or a malfunction when the TV transmits information about its model.
