The second is that the TV motherboard may be welded or in poor contact, and the maintenance personnel need to take a look at the motherboard.

Added: If you jump when using the remote control, it is very likely that the remote control change button cannot be ejected or there is an internal electric shock and leakage, which is easy to check; If it is an automatic jump when the remote control is not used, it is also caused by the local key.
