LCD TV power board replacement

[crowek]

Hello,

The cheapest DIY fix seems to be to clip a jumper wire on the power board, but my Dad won't OK that option. Looking at the components, it seems to me like swapping the power board out is no different in principle than swapping out a sound or video card in a PC; unplug cables, loosen screws, detach clips, replace board, reverse steps 1-3 in descending order.
Before my Dad will sign off on the idea, though, he wants to know about the risk of electrical shock. Besides the obvious need to unplug the power cord before opening the cabinet, are there other electrical shock risks that would make the DIY plan a Bad Idea?

Any help will be apprecited.

I didn't find the right solution from the Internet.
