Chosen Solution

Hello: I have an LG47LN5750 and while swapping out my Playstaion 4 with the Nintendo Wii u, the HDMI port was pushed into the casing of the TV. I then attempted to use HDMI 2 and the same thing happend. Luckily, HDMI 3 worked without incident. I have swapped out other components before so I am not sure if I wore out what holds the port in place or whatever. Is there a way that I can just remove the back case to this TV and put them back? What is holding them in place? Thanks for any help, Paul

Hi Paul, So I would simply take the TV apart. Then you can look at the mainboard and see if it needs to be replaced. I am going to assume it does BUT it may not and the mounting bracket could have just come loose.

This is where the mainboard should be on your TV if you provided the correct information. Outlined in orange.

This is an image of where you will find the label for the MAINBOARD part number a simple google for this and you should find it pretty easy and cheap. It is not that uncommon for this to hapce. Outlined in Orange. Some sidenotes it do not rest your hands on anything inside the TV as you may cause damage to your set. Also, wear gloves if possible (latex) this will aid in keep oils/moisture from your skin getting on components. Hopefully you just need to reattach the plate. Best of luck, hope this helps.

your best bet is to open the TV and see what has come loose. if you lucky it is either a metal casing soldered to the PCB or a plastic casing thats broken. If this is the case and you are capable you can solder it back onto the board or glue plastic casing. Just take care that you dont induce any static into the board as you could blow some of the LSI chips on the board. then reverse the order you took it apart. Best if you strip, take a photo every step of the way so you dont end up with spares once you have closed up again. Good Luck

i had the same issue i ended up with a new main board

Where it’s possible to buy hdmi port for the tv ? Hdmi port female with 21 pin vertical 180° for to solder and repair the hdmi connector. I search it but only 19 pin i see in the web! :(
