4200, 4000, 4002, 3500, it makes no difference they are all the same!!!!!
There is nothing wrong with the stand! It is the one for the job. The 4 screws are provided to hold the TV to the stand.
Having said that, you probably have the same 4 screws still in the bottom of your TV.
Cant help you much more from here as I dont have one I can photograph at present. Easier to work out if you turn the TV on it's side.
The wire coathanger thingy will get in the way, you can remove it but the stand will go on without doing that. It is not rocket science!!!
