No sound

[Maybeyes1]

I used to have sound at a specific angle on my Ds lite and sometimes it did work, but know it just doesn't work. I think it's the ribbon cable connecting the screen and motherboard together but I think it's the actual speakers because when it used to work it only the right speaker was working

Probably desoldered. Open your console and check.

In general electronics then only working at a certain angle does usually mean some kind of ribbon cable is fractured or a solder joint needs the aid of gravity to work (either by making a connection or preventing a short).

You can test speakers. Get a dead battery (important that it is dead, or if not then a suitable resistor) and throw some wires around. You can see the cone then move in response to it, normally done if you have a speaker of unknown wiring (seen a few car ones be this) as reversing the polarity will change the direction it moves and you can then pick wiring accordingly.
