When touched, the TV may still shake slightly even if the TV and stand are assembled correctly. However, there is a possibility that the machine screws are not firmly attached. If shaking happens between the stand base and the stand neck, the stand neck and the stand head, or the stand head and the main body of the TV, confirm that the screws are securely tightened using the recommended torque in the supplied stand supplement.
NOTE: To know more about the proper assembly of the TV and the stand, check the specifications or supplied operations guide. Manuals are posted on your model support page.
