According to official specifications, the 60-inch Xiaomi TV 3 uses an LGD IPS panel, and the panel information and internal structure are our main concerns.

Our tools include a multi-function screwdriver, electric screwdriver, crowbar, and magnifier.

Remove the twenty-two screws securing the back cover.

After removing the screws, the plastic back cover can be easily opened.

After removing the back cover, the internal structure is extremely simple. Compared to other brands’ 4K TVs, the craftsmanship of the Xiaomi TV 3 is indeed outstanding.

Let us look at the circuit board. TheĀ arrangement of various components on the circuit board is very reasonable, and the craftsmanship is also excellent.

Hello. Great teardown! I have a Mi TV 3 60-inch and have a problem with the TV signal output and the image processing unit board. The screen doesn’t seem to recognize the Mi TV bar. The Mi TV bar is working fine, as I’ve tested it with another Mi TV with a 60-inch screen. The Mi port wire cable is working fine as well. The TV is turning on, but I cannot receive a signal from my bar. I’m thinking of replacing the board where the Mi port is attached. Please help me find a replacement board. I would appreciate it. I live in Kenya and want to repair it.
Thank you.
Is this a good TV, at $320?
