售后安装电视挂墙上一般都是需要收费的，无论是从电视厂商或者安装服务商的角度来看，都需要考虑一定的成本和利润空间。通常情况下，售后安装电视挂墙服务的收费标准取决于多种因素，如挂墙的高度、墙体的材质、电视的尺寸、距离等因素，费用也会因这些因素的不同而有所区别。

电视挂墙安装需要一定的专业技能和工具，一般由专业的售后服务人员进行安装，他们会根据你的要求，为你提供全面的服务。售后安装电视挂墙上的费用可能包括工程费、材料费和其它附加费用等。在一些情况下，如果需要重新修建墙体等特殊工作，收费也会有所不同。

大多数电视 manufacturers offer professional installation services， and the fees for these services vary depending on several factors， such as the size and weight of the TV， the type of mount to be used， and the location of the installation. For example， wall mounts for larger TVs may be more expensive than mounts for smaller TVs， and if your installation requires any extra work， such as drilling additional holes or reinforcing the wall with extra support， these additional services may incur an additional charge.

In general， the cost of professional installation services for wall-mounted TVs can range from a few hundred to several thousand dollars， depending on the size and complexity of the installation. Some manufacturers may offer discounts or promotions from time to time to make their installation services more affordable， so it may be worth checking with them to see if any current discounts are available.

In conclusion， while the cost of installation services for wall-mounted TVs can be significant， it is often worth the investment to ensure that your TV is installed safely and effectively， and to save you time and hassle in the long run. If you're unsure about the cost of installation services， consult with the manufacturer or a professional installer to get a better idea of what to expect.
